But probably something like 95% of the most fatigued and stressful motions. Pretending that the 120th pitch is at all equal to the 1st is silly. thats probably not true when you look workout sessions. just go dig back through the 1960s stuff. You get stories of guys throwing 150 pitches consistently. Let's not be stupid, these guys could throw in the low 90s with good power curves and other things. Whatever difference there is now is minimal. Like i said there's little, if any, evidence to backup the claim that high pitch counts cause injuries. The actual motion itself is what's most important. If you have a problem with your throwing motion, like Prior does, every single throw you make hurts you. Regardless if its on the field or in the bullpen. When you look at that, the impact of 10-20 additional pitches becomes very small again. BR has pitch counts from 1988 on for Clemens (his age 25 season) 1988: He threw 150+ pitches four times. He threw 140+ another three times. He threw 130+ six more times. 1989: He thew 130+ 12 times, including 2 150+ games. Over the course of those two seasons he had 25 games with 130 or more pitches. He's been fine since. After 1990 pitch counts became more visible and the media started to scream about them so his PC slowly declined with time but he still went 130+ quite often. Let's look at Orel Hershiser! 1988: He topped 130 pitches once. 1989: He topped 130 pitches five times. Guess who missed most of the 1990 season with shoulder surgery? Not the guy who had the higher pitch counts. Let's look at Nolan Ryans 1989 season. I would assume that more pitches on a 42 year old arm would be more damaging than on a 23 year old arm, but thats me. 160-169: 1 150-159: 1 140-149: 5 130-139: 9 120-129: 5 110-119: 5 100-109: 4 090-099: 1 (99) Unknown: 1 He was fine. 1990 and 1991 were much of the same. He threw even more pitches when he was younger. Theres NO doubt in my mind that the arms in the 60s, 70s and 80s had more pitches than todays and as much torque. Arguing otherwise is stupid. that's just a couple guys though. i can just as easily say here are two guys (wood and prior) who were effected by high pitch counts.
