For all intents and purposes, Ben Brown has relied on just two pitches so far this season. His 97 mph fastball makes up 63.7% of his repertoire while his 87 mph spike curve accounts for another 34.5%, and that combo has led to very strong results if we remove his MLB debut in Arlington. If Brown is going to stick as a starter or even a long reliever, however, he probably needs to develop another option.
Statcast says he’s thrown two sweepers this season, but he ditched that pitch this past offseason so it’s likely just a misclassification of curves that got too slurvy.
