Only four pitchers in Greenhouse?s sample lost as much as 2 mph over the course of 100 pitches: Tommy Hunter (-2.0), Zach Duke (-2.2), Rick Porcello (-2.5), and Jonathan Sanchez (-2.7). It?s perhaps unsurprising to find that two of that group have moved to the bullpen, while a third (Sanchez) has had considerable difficulties since Greenhouse published his piece.
