David Ortiz and HITf/x

by Mike Fast
June 09, 2009

There is a discussion at The Book Blog which began with a link Tango made to a post by John Dewan regarding the declining length of David Ortiz's air balls and has evolved into a discussion of batted ball speeds as measured by HITf/x. It's worth your time if you're interested in the new HITf/x data. I posted a couple graphs in post #18 regarding how batting average is affected by the speed of the batted ball and the vertical launch angle.

Mike Fast is a Kansas City Royals fan who enjoys investigating baseball questions using PITCHf/x data. He welcomes questions and comments via e-mail.
