To put that into perspective, hard throwing Ken Giles has a lower Bauer Unit fastball than Marco Estrada, who rarely exceeds 90 MPH. In reality pitchers can throw 92 and have spin rates ranging from 1800 RPM to 2400 RPMs. Last year, his spring rate was around 2400 rpms and this year it was over 2800 rpms without an increase in pitch velocity. But perhaps the most impressive thing about his fastball was its . Take a look at the difference that an extra 100rpm can mean. A horrific all consuming monster that has been brought by the devil through his tool Chaz Roe to make hitters suffer. Question Where does velocity come from in pitching? 70-80 mph. In terms of RPM, Garrett has an elite curve ball. We use cookies and other tracking technologies to improve your browsing experience on our site, show personalized content and targeted ads, analyze site traffic, and understand where our audiences come from. His 2,294 RPM fastball spin rate was only average, but his Active Spin was an insane 99.5%. "http:":"https:";if(/^\/{2}/.test(i)&&(i=r+i),window[n]&&window[n].initialized)window[n].process&&window[n].process();else if(!e.getElementById(s)){var a=e.createElement("script");a.async=1,a.id=s,a.src=i,d.parentNode.insertBefore(a,d)}}(document,0,"infogram-async","//e.infogr.am/js/dist/embed-loader-min.js"); The 6th pitcher threw pitches from 60 80 MPH but was told to attempt to change his mechanics from pitch to pitch and you can see that the R^2 relationship dropped down to .541. 68 mph. This assures both the coach and athlete that the time and effort spent making said adjustments do not go to waste. Baseball Pitching Velocity Chart from age 8-22+. Average cruising speed for a good high school pitching prospect at 14 to 15 years old would be about 75 mph. Weve seen that spin rate increases with fastball velocity, but its also easy to misapply basic lessonsespecially if you are comparing pitchers with different velocities. This was examined in 2015 in the Baseball Prospectus annual report. They are getting thrown harder and harder, and more often now than they've been in many years. Sure enough, Betts has proved to be one of the best hitters in baseball when it comes to swing decisions. GameThread: Tigers vs. Yankees, 6:35 p.m. To learn more or opt-out, read our Cookie Policy. We now know that instead of simply repeating cues verbatim to players, learning more background knowledge of certain topics is needed. In this case, the closer the spin efficiency (or active spin, as it's also called) is to 100%, the better (in most cases, because a lower efficiency is tied to more movement in the specific. The Reds don't have anyone remotely close to being elite in terms of spin-rate. 66 - 74 MPH. In order to qualify for a specific pitch type, a pitcher must use it at least 5% of the time. All this is discussed (and examples given) in the linked article. But if you tell me the spin parameter as I called it, was 0.2, I could tell you the lift coefficient was roughly 0.2. Curve balls today are not your grandpas big loopy silly bugs bunny slow hooks. Centered around 1700 rpm and 83 mph, this . Learn how your comment data is processed. A high spin rate keeps the ball from falling as much as it travels toward home plate, creating what's know in pitching parlance as "ride." Conversely, a low-spin fastball is most effective when thrown down in the zone as it gives the ball a sinking action that often results in a lot of groundballs. Curve balls are the same to a certain point. Click the link, its a gorgeous display. A sweeping, high spin rate curve will get more swings, but some of those will be harder hit than those of a more vertical curve ball. This is meant as a brief overview and discussion on this most meaningful of statistics, but is not a definitive guide. Curveball. Familia getting wrecked via statcast. Perhaps a lower spin rate. [] first test is more of an extension of our last blog post about spin rate, but shows off a major plus of the Trackman radar device an excellent back-end that [], [] strike. 70-80 mph. Most washing machines now come with a variety of speeds for you to select, helping to protect your more delicate clothes or wring out other clothes more efficiently. Your head might be spinning from the more complicated sections at the end, but there are a few key points for coaches and players. God Bless you man. However, this conclusion isnt so simple, and we need to look deeper to find better context. By having a pitchers predicted and actual spin rate alongside his predicted and actual spin efficiency percentage, were able to compare what wed expect his transverse spin rate should be compared to what actually occurs. What's a good fastball spin? So we can say that at the same velocity the higher the spin rate the more swing and misses the fastball is going to get. Each pitcher is going to have a small range around their average spin rate. It is important to remember that coaches are looking for pitchers to consistently throw at this velocity, not just touch it every once and awhile. In 2016, there were over 255,000 four-seam fastballs thrown, and the Major League average four-seam spin rate was 2,264 rpm. 1989. But if you divide your Bauer unit by 120, you essentially have the unitless tangential velocity (radius * spin rate) divided by forward velocity. Here is an illustration of a 92mph fastball thrown with 2400 rpm, 2200 rpm, and 1800 rpm. His four-seam fastball sits 91-92 mph on average, touching 94-95 mph at peak, with spin rates that average between 2,600-2,700 rpm, hitting as high as 2,850 rpm on the Cape. What Is A Good Spin Rate For A Curveball? In reality pitchers can throw 92 and have spin rates ranging from 1800 RPM to 2400 RPMs. Why? Sharp changes from that normal range can be seen as an early sign of unhealthy fatigue. As you mentioned, Bauer Units were created to a) simplify the relationship between spin and velocity during ball flight b) simplify a pitchers ability to generate spin at a given intent level. Max lateral deviation was 24 inches (more likely 18 inches.). So a good part of the movement of a fastball depends on how fast or how slow, called the rate, it is spinning." An increase of 300 RPMs for a spin rate is highly significant. The chart below is based on MLB data showing the average pitching velocities based on age. Breaking ball spin rate is easy to figure out. Hacking The Kinetic Chain: Hitting Is Available For, In a previous article, we discussed the difference between. Splitter. The heavy, usually refers to a late sink the ball has, resulting in hitters not hitting it squarely usually on the top half of the ball. Lower spin fastballs the reverse, less swing and misses and more ground balls. This metric is designed to identify fastballs in the big leagues with the greatest potential to increase total movement based on a pitchers inherent spin characteristics. The simple answer is that spin rate affects where the ball ends up when it reaches the batter. While it seems trivial, that extra 200rpm is the difference between a swinging strike and an absolutely smoked baseball. This was best typified by Lance McCullers (who will show up again shortly) throwing 24 straight curve balls to Yankees hitters, completely dominating them. Weve seen that spin rate increases with fastball velocity, but its also easy to misapply basic lessonsespecially if you are comparing pitchers with different velocities. With only a few miles per hour standing in between a Division I and a Division II player, it is evident that with hard work and proper training, you can work your way up to the next level. But his spin rate could max out at 1900 at 92 MPH. or is some of it proprietary data not publically available? This article was co-written by Dan Aucoin, Michael OConnell, and Eric Jagers. Because we want pitches that are further away from the average spin. The spin cycle on your washing machine refers to the spins per minute (or revolutions per minute: RPM). 1944. If you throw a drop with "average" spin, then you don't have a very good drop..because everyone throws a drop with that amount . But they all tend to be more successful the higher the spin rate. One of those topics is spin rate. Garrett Richards has a devastating Curve. However, I cannot stress enough that these are only averages, and there is very limited data to go on here. ERA = 9 X (Earned Runs Allowed / Innings Pitched) If you have a look at the formula above, the first step is. As baseball prospectus writer Alan M. Nathan explains, The reason has to do with the vector nature of the spin: It has a magnitude and a directionand can be represented with Spin Vector (W), Gyro-spin (W2), and transverse spin (Wt). A Bauer Unit is derived from Spin Rate (RPM) / Velocity (MPH). This idea was also explained further in these Fangraphs pieces: A New Way to Study Pitching Injury andPitcher Spin Rates and Injuries. If a pitcher is spinning a fastball at 2400 RPM, that is less impressive at 99 MPH and much more impressive at 89 MPH. I'll get to how that applies in a minute. Rather, as you may have noticed, most of these pitchers are sinkerballers by trade, and any increase in transverse spin would impart more carry onto their fastballs. 62 mph. His splitter/sinker had too much spin, so it didn't sink. Lastly, a low slot or sidearm pitcher, will likely have a fastball spin axis thats almost purely vertical. Most change-ups have less spin rate due to grip orientation and a more tilted spin direction. For kicks, here is a separation of Verlanders Fastball, Curve, Slider, and Change-up. Now, based on reading the above chart, it would be easy to conclude that high-spin fastballs should be thrown high in the zone and low-spin fastballs should be thrown low in the zone. For example, in looking at the 2018 leaderboard above, we see that Tyson Ross threw his two-seamer (FT) with an additional 347 RPMs of raw spin compared to what we would predict given the velo and axis on the pitch. And that at a certain point higher spin rates for curve balls and breaking pitches become dramatically less impactful for their total movement. The lowest spin rate is 1767. When a fastball is thrown with backspin, we can explain its vertical movement with Magnus force. This article is intended to build a basis of knowledge of what we, at Driveline Baseball, understand about spin rate at this current time. When combined with higher velocity, fastballs are often even more effective with more spin. This was examined in 2015 in the Baseball Prospectus annual report. Forkball. Next youll need to look at the pitches spin axis. Spin Rate Part II: Spin Axis and Useful Spin, This article was co-written by Assistant Researcher Michael OConnell, Engineering Intern Joe Marshand edited by Kyle Boddy. Spin Rate is important to a fastball, with fastballs below 1800 rpm and above 2600 rpm being vastly more effective than those that ride the line in the middle. Rapsodo calculates spin axis directly, but infers trajectory based on the axis itself. Lastly, how spin axis is measured depends on the technology used to track ball flight. Those above 1750 rpm tend to exceed a 50% ground ball rate. Generally, 14 year old average cruising speed would be about 65 mph. In other words, a high-velocity, over-the-top pitcher who is actually less able to use a combination of finger forces and friction to add spin on the ball at release could produce a higher spin rate than a low velocity, sidearm pitcher who can generate spin well. This gif was created from a fantastic video on the Magnus effect from Veritasium titled: What Is The Magnus Force? As a result, nearly all the movement will be lateral to the arm side. But what Alan notes and explains here is that spin rate is still a science in progress, and the data is still not perfect. So, for a sinker to sink, or a fastball to be heavy, it needs to be thrown with less spin than a normal fastball. As you can see, there is a lot of depth to the discussion around spin rate. After I was cleared (after flexor tendon) surgery, doing forearm work has been . This ball is traveling to the left with backspin, meaning the ball is pushing the air downward behind it creating an equal and opposite force upward. (As for whether high or low spin on a fastball is betterthat's a topic for a different day.) apologies. Sometimes its a lot slower and more dramatic, but this year he's higher spin slider seems to be the norm. The lower the spin rate, the lower the ball will drop. Though this is merely a starting point for more research we can reasonably say that spin rate is an innate characteristic but unknown mechanical changes may also affect spin rate. You Asked What kind of dirt do you use on a baseball field? I highly recommend reading THIS article from the baseball nerds over at []. Answer: Statcast combines doppler radar and high speed video technology to generate s datastream for every play during a game. He wasn't the only one to increase their spin rate as many other pitchers saw increases but most of their increases were in the 200 rpm range. Bauer Unit?? Active Spin Leaderboard Spin rate also operates within the confines of the Magnus effect, which I have touched on briefly before, is simply the effect of spin on how much a pitch resists the effect of gravity. A higher spin rate fastball will appear to rise, and is more difficult to square up. Fastball increased by 1.2mph to 97.1mph in that same time frame but the big jump came in his spin rate, which is now averaging at 2530rpm. You have ended my 4 day long hunt! Let's look at two different curveballs from Richards that differ in spin rate by about 500 RPM. That is almost double in 2 years! What is a good spin rate on Rapsodo? However it also depends on the break of the pitch and they type of curve that is thrown. With these two things alone, a heater can do wonders. While they focused on pitchers at the start of Clean Fuego, he says the device can not only help with pitch design and fundamentals but it can also help every position player improve throwing efficiency. A high percentage of backspin with a horizontal axis causes most of the spin deflection to be in the positive vertical direction. A high-velocity fastball with a low spin rate may not be as effective as a low-velo heater with a high spin rate. It would slot into the small "dead zone" between the purple blob of the slider and the red/orange blob of the fastball and sinker. This gif was created from a fantastic video on the Magnus effect from Veritasium titled: The Effect of Fastball Backspin Rate on Baseball Hitting Accuracy. Remarkably, in terms of pure spin, its unremarkable. This isnt surprising for four seam fastballs, as a greater spin rate leads to arisingeffect in which the ball crosses the plate at a higher point than where the batter expects. Learn how your comment data is processed. SVR+ = (Player SVR/League Average SVR)*100. Similarly, Bumgarner has less extension on his fastballs than in 2016. It describes the percentage of the raw spin rate that directly impacts the pitchs movement. Its a beauty. Other pitchers may have slight fluctuations in their release point, or fingers at release, that can change their spin axis, which can be adjusted given proper video and spin-rate feedback. Jeff Long recently examined the correlations between spin rate and swinging strike%, GB%, and FB% and only found very small relationships with regards to spin when looking at all pitches. A lot of pitching folks talk about the real value in pitching data to be in the spin rate numbers. This can be attributed to the axis shifting to a more diagonal positionmeaning more sidespin. that scored highest in our pitch potential metric. Knowing your spin helps you better understand what type of pitcher you are at present. With this information, we can then calculate a Spin Efficiency percentage, which expects that Ross would generate ~2,190 rpm of transverse spin on his two-seamer during the 2018 season. However, in looking at his output for the 2018 season, we see that Ross came up about 291 rpm short of that figure and only 14 rpm higher than what we would expect an average pitcher with an average spin rate would produce at his axis and velo. Spin rate is important to understand, because it can affect. A baseball scout will sometimes refer to a fastball as a . obody truly knows how to reliably and consistently change the spin rate of pitchers. Two-seam Fastball. As always, Go Tigers! The efficiency, axis, and slot are what is most important and make the biggest impact on the pitch movement. First, there are many different variations of the curve, straight, power, knuckle, 12-6, 11-5, etc etc etc. There really is no a + b = c magic formula where player x needs to throw a fastball with a specific axis and efficiency percentage to have more success. For example in 2019 Mike Minor had an average spin rate of 2650 RPMs on his fastball, ranking 4th in the majors. To put this into perspective, the best spin rate in baseball is 2658 (among the qualified 400+ pitches thrown group). Pitch Type report shows Average Speed by Pitch Type in the Majors Sources All except below are based on radar readings by the editor. This is a meaty and hard to understand concept, but in its simplest form (Alan is a mathematical savant and the defacto expert at this area of analysis, I attempted to get ahold of him but failed) is that not all spin is equal, that transverse spin is valuable to fastballs, higher spin rates mean more lateral movement and lower spin means more vertical movement. The ball spins, pushing the air downward behind it and creating and equal, opposite force upward. If we picture a four seam fastball, which is thrown with backspin, the more backspin the less the ball is going to drop over its course from the pitchers hand to the catchers glove. We now know that instead of simply repeating cues verbatim to players, learning more background knowledge of certain topics is needed. 15. can tell us that the spin axis of each pitch significantly correlates with the orientation of the hands and fingers just before and at ball release. So pitchers may be able to increase their velocity and spin rate but we dont know where they will end up on the scale of 1800 2400 RPM for fastballs. The [], [] weve seen that fastball spin rate scales linearly with velocity, we asked our athletes to throw between 75-80 mph, meaning we used Bauer Units to compare the [], [] Higher spin rates mean that the ball drops less on the way to the plate. But the axis can change depending on arm slot and the orientation of the hand and fingers at ball release. Higher spin fastballs tend. ?, lets toss years of aerodynamic research in the trash. This metric is designed to identify fastballs in the big leagues with the greatest potential to increase total movement based on a pitchers inherent spin characteristics. Lower spin fastballs the reverse, less swing and misses and more ground balls. kind of a dumb question, but Is there a way i can access this data myself and make my own spreadsheet, similar to the ones showed in here? An increase in spin rate can add more movement to breaking pitches. as well as how technology is changing baseball. This would also work hand in hand with monitoring a pitchers velocity. In this instance the effects of high and low spin rate most likely equaled themselves out. Three years ago, he said he participated in laboratory experiments that determined that pine tar on the surface of a baseball could improve spin rates by 300 to 400 revolutions per minute. Most change-ups have 7-10 MPH separation between the fastball and the change-up, going off the idea that a change-up is supposed to get a hitter to think its a fastball, and swing over and early. The fastball also has an above-average spin rate, ranking around the 70th . as much as 500 rpm on pitches like the fastball! Fastest, straightest pitch. When looking closer to see if a pitcher cuts his fastball we need to understand that some pitchers have essentially grown up cutting the ball when they throw a fastball, which is incredibly difficult to change when theyve thrown thousands if not millions of pitches with that pattern. thanks. Normalized, the average pitcher has a Bauer Unit of 24, with more velocity or spin increasing the Bauer unit. Both Trackman and Rapsodo measure spin axis but in different ways. A higher spin rate fastball will appear to rise, and is more difficult to square up. Moving on. Nearly 75% of curve ball spin is "useful". If someone if sitting right in the average range then we move on to looking at the other pitches he throws. Slurve. Considering the acceleration phase of the throw lasts anywhere from 30-50 ms the suggestion that spin may be generated in only 6 ms(or just longer than that) of the motion is incredible. A SVR+ of greater than 100 would indicate a higher than average spin rate fastball, where as a SVR+ of less than 100 would be a lower than average spin rate fastball. Although Edwards Jr. boasted the second highest fastball spin rate of any pitcher in the big leagues in 2018 with at least 75 fastballs thrown, Spin+ believes Triggs ability to spin the baseball is actually ~90 rpm higher than Edwards Jr.s, once you control for the advantage that Edwards Jr. has with regards to velocity and axis. Spin: 100 rpm change * 1.0% SwStr% Velocity: 1 mph change * 0.9% SwStr% When a fastball is thrown with backspin, we can explain its vertical movement with Magnus force. in my limited experience, those would not have much predictive power to Spin. Four-seam Fastball. . In this article, we first look at high-spin fastballs and ball axis, and then we move deeper into the complex nature of spin, axis, and movement. This means the result will likely be between 10:00 to 1:00 spin direction. . Disappointing to see the deleted comment b/c generally you guys consider yourself very data driven. Keeping your hand behind the ball all the way through the release will improve both Spin Efficiency and Speed. Horizontal curves strike out more batters, but result in more hard contact, while vertical curves have a much higher ground ball rate but lower strike out totals, as explained more in depth here. I think its a reasonable question to ask what kind of relationship you found from Spin Rate to Spin Axis and Velo. This idea was also explained further in these Fangraphs pieces: Training for Youth Pitching Velocity: High-Intent Throwing, Rolling Over: How Bottom Hand Supination Affects Bat Path, How the Axe Short Trainer Can Make You A Better Hitter, Youth Baseball Player Development Velocity Aging Curves, Rapsodo, Trackman, and Pitch Tracking Technologies - Where We Stand - Driveline Baseball, Spin Rate and Swinging Strike Probabilities | Exploring Baseball Data with R, Pitch Grips and Changing Fastball Spin Rate - Driveline Baseball, Long Toss and Lazy Thursday The Minor League Offseason Camping Project, Whats Hurting Bumgarner? It would be 10 times the unit less spin parameter but at list the guys who did the ground breaking work wouldnt cringe as much. What is a good spin rate for a high school pitcher? However, it's not always the case that the guys who throw the hardest also have the highest spin rate. Here is an example: Let's say a a fourseam fastball has a spin rate of 1000 rpm and a spin efficiency of 90%. Higher spin isn't always a good thing. recently examined the correlations between spin rate and swinging strike%, GB%, and FB% and only found very small relationships with regards to spin when looking at all pitches. Bartolo Colon 's fastball has 60 percent useful spin while Gerrit Cole 's four-seam fastball has 78 percent useful spin. This site uses Akismet to reduce spam. Two Seam Fastball. 76 mph. The ball spins, pushing the air downward behind it and creating and equal, opposite force upward. Bauer has publicly decried the use of illegal substances to increase the spin rate. His whiff rate in 2019 was 37.5% on fastballs. Gray's sinker is not good by any stretch, but a decent cutter paired with it is an improvement. "He seems to have exceptional feel to make pitches, to manipulate the baseball, to do different things and to be in the zone at a high rate," Baldelli said. The league average in 2017 was hovering around 1700 RPM for change-ups. Still makes more sense. Cutter. A good groundball ratio would be anything over 1.5. Here is a link where Brandon does a stellar job on the subject. So a good part of the movement of a fastball depends on how fast or how slow, called the rate, it is spinning. Here is a great gif illustrating this effect. Using Chapman's average speed and backspin, you can find the lift coefficient and then the Magnus force. Gyrospin causes no change in motion of the ball. This is obviously taking into considering a large assumption that they could throw harder with the same mechanics. Higher spin not necessarily. By having a pitchers predicted and actual spin rate alongside his predicted and actual spin efficiency percentage, were able to compare what wed expect his transverse spin rate should be compared to what actually occurs. Note: Remember that spin and velocity are related, don't combine the first two formulas. We will hopefully answer some common questions that we receive and well as link out to resources that weve found helpful in understanding spin rate. Its inhuman. 7,006. To highlight an example using Statcast data in the illustration below, we see the top ten. A high school pitcher can be anywhere from 14 to 18 years of age. But more specifically, it shows that a fastball at 90 mph (which is lower than the average MLB fastball) at spin rates 2400-2600 produces a greater swing and miss percentage than a 95-mph fastball with a spin rate below 2100 rpm. Here the authors present picture evidence that suggests how quickly the ball goes from not rotating to rotating when a pitcher throws. He gets incredible movement on it, and he can bury the thing anywhere he wants. Low spin rate guys get more sink. Higher spin fastballs tend to be more effective at getting swinging strikes, as illustrated through this mind numbing excel sheet, with the data points representing swinging strikes. This typically is denoted, S, on lift coefficient versus S plots. For fastballs and changeups, the higher the spin rate, the less the ball will sink as it approaches the hitter. The basic premise is, the higher the Bauer Unit, the more effective the pitch. Ouch. This means that Ross is essentially throwing his two-seamer (and four-seamer [FF]) with just league-average movement, despite being amongst the league leaders in generating spin. You often hear so and so has a curveball with a 3,000-rpm spin rate, or a fastball with 2,800 rpm spin rate. 58 - 65 MPH. Mostly because no one knows why the ball spins differently from pitcher to pitcher. This is a compilation of knowledge gleaned by some seriously ingenious folks, please patronize their sites, click the links, and subscribe to their various sites and pages. Even more specific, you can have two pitches with the same velocity and spin rate but have different movement profiles based on the axis of the ball. In a previous article, we discussed the difference between cues and measurements as well as how technology is changing baseball. Craig throws his Knuckle Curve anywhere from 85 MPH to 90 MPH. In order to better compare spin rates at different velocities between pitchers we created Spin to Velocity Ratio (SVR). Frequent Question What is a good spin rate baseball? To quote my last fanpost. A pitcher who can also make his fastball dance, however, is going to be even better off. We can also look at the relationship of fastball spin rate (while holding velocity constant) and its relationship to swinging strike percentage and average launch angle. 4-Seamer Movement 5 0 5 Horizontal Movement vs Avg (Inches) More Break Less Break 8 6 4 2 0 2 Vertical Movement vs Avg (Inches) More "Drop" More "Rise". Curveball Curveballs and sliders typically will register the highest raw spin totals of all pitches (MLB average spin rate 2430-2530 rpms), though these ranges can become more inflated based on the gyroscopic spin measurements of each pitch. This takes some getting use to, but recognizing what pitches have the potential to be good or bad is the first step in using technology. Rather, we need to consider the constraints of the individual alongside a proper game plan to formulate something that will work best for an athletes specific skill set. For pitchers that come to our facility we can use either Trackman or Rapsodo to get measurements of their spin rates and then make recommendations on how to best use their pitchers or make tweaks to improve their pitches. Just like not every pitcher throwing 90 has a low spin rate. Used Resourses: Editor's note: If you enjoyed this article, check out a couple more JajaBojangles' posts on the fastball and the changeup. I'll wait. At one point, he had thrown 2000 curveballs while only allowing 5 home runs off the pitch. This means that as a rule, the higher the spin rate the better movement the pitch gets. That may not seem like a big deal, but at 2400 rpm and at 1800 rpm, there is more than enough movement to avoid the barrel of a bat, getting either a pop up, strike, or ground ball. As we can clearly see, spin rates are essential depending on the pitch. As discussed, fastballs with higher spin than the MLB average of 2,263.15 seem to "rise", as in they stay up higher than the aforementioned average spin fastballs. The R^2 values between velocity and spin rate of the first 5 pitchers ranged from 0.83-0.96 which is quite a high relationship! This pitch was a blazing 88 mph. Two-Seam Fastball: Adrian Houser, Milwaukee Brewers Gyrospin and Sliders While spin rate is important for sliders, there is another type of spin that comes into play, gyrospin. And according to Passan, even that could get you busted. Picture from: Baseball Spin and Pitchers Performance: Kanosue, et al. Enough pining for days gone by, for the opposite end of that spectrum, we turn to soft tosser. Karcher used to be more obsessive about spin rates and other analytical . What we do know if that there is good evidence that spin rate is created in an incredibly short amount of time.
