BETA Feature:
Basic description of 2015 pitches compared to other RHP:
His splitter comes in below hitting speed, generates more whiffs/swing compared to other pitchers' splitters, results in somewhat more flyballs compared to other pitchers' splitters and has slight armside fade. His fourseam fastball comes in below hitting speed, generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has good "rising" action, results in more flyballs compared to other pitchers' fourseamers and has slight armside run. His cutter (take this with a grain of salt because he's only thrown 5 of them in 2015) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' cutters and is an extreme flyball pitch compared to other pitchers' cutters. His sinker (take this with a grain of salt because he's only thrown 1 of them in 2015) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' sinkers, has an obvious tail, is an extreme flyball pitch compared to other pitchers' sinkers and has little sinking action compared to a true sinker.
