The ten-second 100-meter sprint. The four-minute mile. The 2-hour marathon. In baseball, is the 110 mph fastball the subsequent large quantity to fall? What really is the higher restrict in relation to skilled pitchers throwing their quickest pitches?
There’s some debate about what the quickest fastball to this point has been. Within the documentary Fastball, filmmakers checked out a couple of key moments from the previous. Bob Feller threw a ball sooner than an 86 mph bike. Nolan Ryan was clocked at 100.8 mph by a radar gun in 1974. When you convert Ryan’s quantity to the out-of-the-hand methodology used to measure pitch velocity as we speak, you get 108 mph. For some, that counts because the quickest pitch on document.
We’ve been monitoring major-league pitchers with the identical high quality of know-how since 2007, although, and no one has thrown tougher than Aroldis Chapman and his 105.8 mph fastball in 2010. So Ryan’s 108 could be a big departure from 15 years of monitoring pitches — and, for what it’s price, it’s a big departure from radar gun readings over the remainder of his recreation that day, in addition to the remainder of his profession, which often topped out round 96 and 97 mph.

Since these different pitchers have been clocked utilizing outdated know-how, it’s in all probability fairest to name 105.8 mph the trendy document in fastball velocity. In order that’s how briskly a human has thrown the ball. However what’s the quickest a human being may throw the ball?
“While you construct up a easy physics mannequin that’s basically a sequence of collisions between physique elements, you get a max fastball velocity of about 125 mph,” stated Jimmy Buffi, who has a PhD in biomedical engineering. Buffi is a former Los Angeles Dodgers analyst and is a co-founder of Reboot Movement, a participant growth consultancy agency.
“We’ll want to make use of new strategies,” stated Kyle Boddy, present Boston Purple Sox advisor and the founding father of Driveline Baseball, a participant growth lab and consultancy firm. “If there’s a approach to proceed on, it received’t be with present strategies. Utilizing the most effective mechanics from elite pitchers, piecemeal, is unlikely to be the best way we are able to create the 110 mph pitcher.”
Others thought concerning the potential for damage on this pursuit – pitching accidents have been up with velocity, in spite of everything. Perhaps we’re already on the restrict?
“I don’t suppose persons are going to have the ability to throw that arduous,” stated the Dodgers’ Bobby Miller, the league’s third-hardest throwing starter, about numbers like 110 and 125 mph. “You attain a sure level the place your arm will in all probability break.”
That’s three totally different solutions. Let’s take a better take a look at every.
The case for 125 mph
There’s an idea in pitching known as the “kinetic chain,” which describes the switch of drive from the bottom, and the bigger muscle groups within the legs, up by means of the core and out to the tip of the arm. When you work in a purely theoretical area, that chain is mainly a bunch of interactions that try to preserve the momentum created down low because it travels out to the arm. Buffi’s job at ReBoot is to assist make these transfers as environment friendly as potential. He created a physics mannequin to explain them for the needs of answering this query.
“To provide you with this toy instance,” he stated, “I considered the pitching movement as basically a sequence of vitality transfers between two lots, much like a big ball colliding with a smaller ball. The legs are the bigger mass, and so they switch vitality to the torso, which transfers vitality to the higher arm, then to the forearm, then to the hand, then to the ball.”

The relative sizes of every of these muscle teams govern the quantity of vitality that may be transferred in every interplay, simply as it’s within the traditional physics drawback during which a large ball hits a smaller ball. Within the mannequin that Buffi created, a 200-pound particular person placing 500 kilos of drive into the bottom whereas being 85 % environment friendly in his transfers (an effectivity that’s elite, however inside the vary of chance, in his estimation) would throw 125 mph.
“Though it’s a toy instance, if you put in cheap vitality switch numbers and floor response drive values, you really get cheap pitching velocity estimates,” stated Buffi.
One in all as we speak’s hardest throwers, Oakland nearer Mason Miller, agrees that the scale of the participant and drive into the bottom was a typical denominator if you take a look at the toughest throwers.
“Bodily, I’m 230 kilos, perhaps 240 at my greatest. Chapman is like 250 kilos,” stated Miller. He has thrown the fourth-fastest pitch this season at 103.7 mph, which trails solely a pair Chapman fastballs (one at 104) and one from Angels reliever Ben Joyce. “Power manufacturing into the bottom is vital, we’ve seen that from drive plate testing, that’s an excellent measure of energy manufacturing.”
However there are some flaws on this case. Floor drive reactions north of those Buffi used have been recorded already by athletes at Driveline Baseball, and so they didn’t throw 125 mph. It’s method out in entrance of what’s been noticed, as effectively.
Mentioned Miller: “125 looks as if it’s method out of our present existence.”
“Oh my goodness, 125, that’s loopy,” stated Twins’ nearer Jhoan Duran, who has topped out at 104.8 mph.
The case for 110 mph
The research of biomechanics, or the mechanical legal guidelines regarding the motion and construction of residing organisms, has unlocked velocity for lots of as we speak’s laborious throwers. The typical four-seam main league fastball, measured by the identical know-how and methodology, has elevated in velocity each season since Main League Baseball began monitoring it, all the best way from 91.1 mph in 2007 to 94.1 now.
Sam Hellinger of Driveline Baseball shared an instance of how this understanding of the physique has helped gamers practice to get extra velocity. Justin Thorsteinson, a former Division I pitcher hoping to signal on with a company, got here to them throwing 87.7 mph in June and by August was throwing 91.5 mph, and his altering how his shoulder moved was key. Scapular retraction — in rudimentary phrases, how far again the throwing shoulder reaches earlier than coming ahead — has been linked to velocity by biomechanics research as a result of it creates an enormous separation between the hip and the shoulder. As that separation snaps again like a rubber band, torso velocity is accelerated, which is then transferred to the arm. That was an enormous focus for Thorsteinson.
“Primarily based on Justin’s bio report, we decided that his most obvious want mechanically was his arm motion, particularly his max shoulder exterior rotation and scapular retraction,” stated Hellinger.
After some work with weighted balls and particular drills, Thorsteinson improved his scores within the particular biomechanics that they have been focusing on, as you may see additionally from this image, which reveals how a lot he improved his shoulder retraction.

So may a 250-pound monster of an athlete refine every of his actions to the most effective of present data and bust previous the 106 mph ceiling in the direction of the 110 mph that Boddy thought potential?
“When you’re getting greater than Chapman, who throws 105, for those who get any greater, you lose coordination,” stated Dodgers starter Walker Buehler. “He’s as large and as robust as you might be, and his supply is all about velo.”
Boddy can also be undecided {that a} large dude, plus the most effective piecemeal mechanics of our time, was the best method ahead.
“We’ll want to make use of new strategies, like simulation of human motion with hundreds of thousands of artificial knowledge factors utilizing machine studying and synthetic intelligence to discover the complete latent area of potential mechanical outputs and muscular contributions to the throwing movement,” stated Boddy. “That is one thing Driveline Baseball has been engaged on for years and is quickly turning into a precedence challenge — primarily for sturdiness enhancements over efficiency good points, although we anticipate breakthroughs in each realms over the approaching years from our Sports activities Science and Analysis groups.”
In different phrases, as a substitute of taking our legendary 250-pound flamethrower after which giving him what trendy analysis thinks is the most effective mechanics within the legs, the torso, the shoulder, and the arms, Boddy is hoping that AI may assist us consider new methods these physique elements may transfer in live performance with one another, in an effort to establish even higher potential mechanics.
May AI do that? Given the speedy rise of that know-how, it appears believable that we may see good points from re-evaluating present processes, even ones that contain the motion of our our bodies.
The case for 106 mph
Let’s flip over to a unique sport for a second. Over within the 100-meter sprint, we now have information going again to the Nineteen Seventies. If we observe the most effective instances by yr, it seems to be like we’re hitting a little bit of an asymptote — as a substitute of huge good points like we noticed within the Eighties and ’90s, we’re preventing over smaller increments of change.
When you altitude-adjust these numbers — working increased up can shave some milliseconds, as we noticed with a few record-breaking runs earlier this century — we’re zeroing in round 9.7 to 9.8 seconds as maybe the quickest a runner can handle in a impartial setting. That is seen by some to indicate that trendy coaching, vitamin, and gear have pushed the physique so far as it might go. There are related graphs in different working sports activities that recommend the identical.
A number of examples from different sports activities:

The utmost pitch velocity appears to be following an analogous trajectory in baseball. Chapman threw 105.8 mph in 2010 and since then, the typical greatest fastball has been 104, with a peak of 105.7 (Chapman once more in 2016) and a nadir of 102.2 (in 2020, after all). The most effective non-Chapman fastball is round 104 mph in any given season.
There are some variations between pitching and working, although. Right here’s the place Glenn Fleisig, the director of biomechanics analysis on the American Sports activities Drugs Institute, is available in.
“Fifteen years in the past I used to be quoted as saying that I didn’t suppose high velocity or the ceiling going up, however I foresee it getting fairly crowded on the ceiling,” stated Fleisig. “It wasn’t a fortunate guess that I pulled out of my butt.”
“When others discuss concerning the ceiling, they discuss physics and statistics. Perhaps by the legal guidelines of physics, perhaps folks may throw sooner. Perhaps the very best quantity may preserve going up prefer it (did) for runners, as a result of the coaching can enhance, the mechanics and biomechanics can enhance, the vitamin and dietary supplements can enhance,” he continued.
“The distinction right here is that we’re pushing this little ulnar collateral ligament to its restrict. We’re strengthening our muscle groups and enhancing our mechanics and vitamin, however primarily based on how the physique is constructed, the ligaments and tendons don’t enhance proportionally to the opposite elements of the physique and the method.”
When that ligament tears, the pitcher wants Tommy John surgical procedure to get again on the mound, and people surgical procedures are extra widespread than ever. How a lot stress that ligament can deal with may be up for debate.
“Nobody actually is aware of how a lot stress a UCL can actually take, due to an issue I name cadavers and robots,” stated Randy Sullivan of the Florida Baseball ARMory on a current podcast. “We decided how a lot stress a UCL can take by means of a cadaver setting the place we discovered that it tears at 35 newton-meters of torque, after which we used movement seize to find out that it might tolerate on a single pitch, it has to simply accept 70-75 nM of stress. We acquired the underside quantity from an individual who wasn’t alive; residing tissue wouldn’t react the identical method. And we acquired the highest quantity from a mannequin, a legendary robotic.”
Fleisig, who authored the research that checked out how a lot stress the UCL may deal with in cadavers, noticed that second quantity in a barely totally different gentle.

“That 70-75 nM dynamic stress from biomechanics evaluation is on the total elbow, and the UCL does a couple of third of that resistance, your bones and tendons assist with that resistance,” he factors out. Taking a 3rd of 75 nM leaves the present stress on the elbow inside the 35 nM most we see in cadavers.
The game may be telling us one thing with the spike in arm accidents. All these torn ligaments, that are more and more tied to top-end velocity by the most effective obtainable analysis, appear to recommend that we’re working up on the bodily limits of that little tendon. Perhaps 106 is all that we are able to do.
“I’ve thought of it earlier than,” stated Joyce, the Los Angeles Angels pitcher who has thrown the toughest this yr and likewise had a fastball tracked at 105.5 mph in faculty. “I might suppose somebody will hit 106.0, however I don’t know if there’s way more than that.”
The place can we go from right here?
The work to enhance the ceiling will go on, it doesn’t matter what accidents say, due to the reward system in place for pitchers who can throw laborious. The very best draft picks, the largest free-agent contracts — these go to the quickest fastballs, and that’s not more likely to change within the brief time period.
Joyce has an similar twin who tops out at 98 mph, with related mechanics and similar genes. So what separated Ben from his brother Zach?
“I didn’t do something particular,” stated the harder-throwing Joyce. “I simply at all times wished to throw laborious, so I attempted to throw tougher on daily basis, stored throwing tougher and tougher, and it will definitely labored out.”
Joyce identified that he hadn’t actually optimized his mechanics or executed something particular in that regard. He’s simply throwing 103 and 104 on pure willpower. He’s additionally somewhat smaller than Miller and Chapman. Perhaps the subsequent child is 50 kilos heavier, has that very same iron will, finally ends up as a reliever the place he can max out on fewer pitches, and likewise optimizes his biomechanics. That situation appears more likely to push the top-end velocity some … however how a lot increased if that little ligament is taking all it might deal with already?
If that mixture of inputs solely pushes most velocity ahead a tick or two, it’d behoove younger pitchers to think about different objectives as they arrive up the ranks. In different phrases, if we get to some extent the place everybody throws tougher than 94 mph within the large leagues, however no one actually throws tougher than 106, perhaps one of the best ways to stay out sooner or later shall be to reveal a pitch combine with various velocities and actions, with good command. Perhaps the success of softer-throwing pitchers such because the Royals’ Seth Lugo, who throws eight totally different pitches from two totally different arm slots, and the Phillies’ Ranger Suárez, who retains the ball on the bottom with nice command, can present new position fashions for younger pitchers.
Because the accidents mount within the seek for velocity, chasing a most quantity that may not even be potential is probably not the most effective plan for a younger arm concerned with making probably the most out of his expertise.
