With some teams moving from their spring training sites to major league ballparks on Friday night, the PITCHf/x systems in a few stadiums were turned on. We have PITCHf/x data for the games between the Red Sox-Dodgers, Rockies-Diamondbacks, Tigers-Astros, Royals-Brewers, A's-Giants, and Yankees-Marlins (partial). A new feature this year is real-time pitch classification, and you can see this in the raw data from these games. I haven't had a chance to digest much of this data yet, but you can see that Bartolo Colon's fastball is checking in at 93 mph, for example.
