This is good stuff, but Berrios is more impressive than this: You have to factor in average pitch velocity as well. Physics says that the higher the pitch velocity, the higher exit velocity when the ball is hit the same way (think about hitting a ball to a wall, the harder you hit it, the harder it will come back) Brent Suter's average fastball is at 85.9 mph and he throws it 60% of the time, his curveball is 73.6 mph and he throws that about 18% of the time, his change 80.1 mph and he throws it 16.4 % of the time, and finally his slider is at 77.7 mph about 6% of the time Berrios's ave FB is 93.5 mph (61%), curve 82.5 mph (27.6%) and change 84 mph (10.3%) If there were a metric that factors this, Berrios's numbers would be way on top there...
