Brad Penny and the Sinker
Let’s forget Jason Motte for a minute. Here’s what’s important about today’s game: Brad Penny is the latest Dave Duncan convert, or at least it seems to be that way. Last season, Penny threw his splitter/change-up about 7.5% of the time. The average speed of the pitch was about 86 MPH. The pitch had about -8 inches of horizontal spin deflection, and 7 inches of vertical spin deflection. This isn’t a pitch to be confused with a sinker. The pitch he was throwing today (mostly those little yellow dots) were 89 MPH on average, with -7 inches of horizontal spin deflection (tail) 5 inches of vertical spin deflection. So the pitch has more speed, lots of tail and more sink.
These pitches are clearly distinguished from his 4-seam fastball, and he threw it 37% of the time. He induced 13 ground ball outs. Welcome to the Cult of the Two-Seam Fastball, Brad Penny.
