For those who did not see this article in the Wall Street Journal this week. Excellent piece. PGStaff I am sure you find this interesting and I am sure you have seen the same thing in youth pitching.
"In the 2003 season, there was only one pitcher who threw at least 25 pitches 100 mph or faster (Billy Wagner). In 2012, there were seven, according to Baseball Info Solutions.
In 2003, there were only three pitchers who threw at least 700 pitches 95 mph or better. In 2012, there were 17. There were 20 pitchers a decade ago who threw at least 25% of their fastballs 96 mph or faster. Last year there were 62, including Carter Capps, the Seattle Mariners' 22-year-old right-hander, whose average fastball travels 98.3 mph, tying him with the Royals' Kelvin Herrera for the top spot in the game."
