Sport Science: Aroldis Chapman



Aroldis Chapman's 105 mile an hour repeater is the fastest pitch ever thrown and that pitch wasn't a fluke in one of the third innings Chapman threw 25 pitches and every one of them was clocked at over a hundred miles now but how does he do it pitching coach Tom house has worked with some of the game's hardest throwers including Nolan Ryan and Randy Johnson what you have here is a CC Sabathia upper body and then Randy Johnson lower body that's why I chose 105 miles an hour first this drop the typical stride length for a pitcher is about 87 percent of his height but chapman strike averages out 120 percent of his six foot for height approaching seven and a half feet this stride isn't just long its vast taking a leap eight tenths of a second 15% faster than average pitchers next shoulder turn the twisting angles between his front hip and his back shoulder create massive torque 80% of velocity comes from hip and shoulder separation elite power pitchers like Randy Johnson create angles of 40 to 60 degrees but Chapman's is close to 65 degrees next delivery the thing that separates him is a lot of pitchers could get to that but how soon is it getting to here the average pitcher uncocks his forearm in seven to nine hundredths of a second Chapman's arm fires in less than four hundredths of a second average pitchers release the ball directly over the front foot Chapman's release point up to 12 inches in front of his foot amplifies the difficulty of hitting him not only does he throw hard he throws close one foot of distance is three miles an hour to the hitters eyes so not only on the real gun 105 but you could almost add three more miles an hour to that you may be looking at the hardest throwing individual that's ever been on this planet and when you're trying to hit the planet's fastest pitcher there's virtually no time to think facing a 90 mile an hour pitch a batter has nine hundredths of a second to decide whether or not to swing but if Chapman unleashes a hundred five mile an hour missile that window shrinks by 66% the batter must make his decision in only three hundredths of a second first sports science on ESPN I'm John Brenkus

  1. I would hate to be the batter that gets hit with this guy's fast ball lollol especially if it was a head shot. Not saying that cause Chapman got hit the way he did , but if he was to hit u in the head , well u wouldn't have any time to get outta the way , and u would be lucky to survive it.

  2. I can't believe that Cincinnati got rid of him. That's a bad man right there on the mound. Wish he was still here with the Reds man.

  3. Ahh sports science. Tom House worked with Nolan Ryan? Lol
    Nolan was clocked at 102 at the front of the plate. Guys today are clocked when the ball leaves the hand

  4. Correction Nolan Ryan if he threw now a day's the fastest he would throw would be 108.7mph fastball don't believe me go to Amazon prime look up the fastball and watch the whole thing.
