Whats the fastest pitch recorded at a MLB game?
The following is a direct quote: Although not official, the fastest observed fastball speed was a pitch from Mark Wohlers during spring training in 1995, which allegedly clocked in at 103 mph. The official record according to the Guinness Book of World Records is 100.9 mph by Nolan Ryan in 1974. Ryan’s pitch was clocked using coherent infrared radar. Edit: (To the guy below) You need a source; without a source anybody could say anything. I could top your Nolan Ryan 103.05 with a Nolan Ryan @ 104, 104.5 or whatever if we’re just posting guesses.
