My understanding is that he's hit at least 94 on a number of occassions. My understanding is that his fastball is pretty fast, and that he had a number of games in which he was throwing 90-94 quite regularly. I think there may be many others where he throws more in the 88-91 range. But, as always it depends on what you're trying to do. An 88-91 2-seam sinker that's located well is a really good fastball. A lot more useful than a 93-96 four-seamer that's straight and wild. Which relates to one of my beliefs about Gallagher. I think he's a smart pitcher who pitches for wins and for outs. I imagine he does a lot of pitching in the 88-92 range to get outs. I imagine he could let it fly and throw for the radar records, but that it wouldn't necessarily help him get outs. I think a lot of pitchers are routinely choosing between throwing as fast as they can, versus throwing for outs. Give up a mph or two for command. Every 2-seam fastballer in baseball knows he could throw faster with 4-seam. Quoting and thanking yourself, huh? :D
