[H]ere are the actual results for fastball velocity, particularly swing and miss percentage and foul balls. The sample includes every fastball that was swung at during the 2008 season, broken down into velocities of 85 mph and up. This yielded a sample of 38108 events. There were a number of interesting trends, particularly the correlation coefficients of fastball velocity relating to swing&miss percentage, and foul ball percentage. To me, the foul ball percentage was the most interesting, but I’ll let you decide. …
Interesting stuff…
