Boston Red Sox
Although he has not thrown an MLB pitch in 2015, Craig Breslow threw 7,112 pitches that were tracked by the PITCHf/x system between 2008 and 2014, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2014, he relied primarily on his Sinker (89mph) and Fourseam Fastball (89mph), also mixing in a Cutter (86mph) and Change (78mph). He also rarely threw a Curve (76mph) and Slow Curve (70mph).
Basic description of 2014 pitches compared to other LHP:
His sinker is a prototypical pitch with few remarkable qualities. His fourseam fastball has slightly below average velo. His cutter has little cutting action. His change has below average velo, results in more flyballs compared to other pitchers' changeups and has a lot of backspin. His curve is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves and has little depth. His slow curve (take this with a grain of salt because he's only thrown 19 of them in 2014) is a real yakker that's separated from his other curveball due to its big drop and slow speed.
