His average fastball velocity was down about 1 mph from a season ago. He dealt with back trouble early in the year, which affected his velocity a bit. He also is entering his early 30s, when most guys lose a tick or two (without steriods).
His fastball has fallen off about 3 MPH over the past 6 years, which is not unusual. And he has had tremendous success with decreased velo, because he's never been a guy who relied on blowing people away with velocity. Movement and control are his keys, and he still has plenty of both.
