Left-hander Drake Britton came into his first big league camp in excellent shape after a full offseason of workouts. While he endured a brutal struggle in 2011, going 1-13 with a 6.91 ERA for High-A Salem, there were some interesting developments that could bode well for his future. First, after being limited to 75 innings in 2010 in his first full season after Tommy John surgery, he was healthy for every start of the year, taking the mound 26 times. Secondly, when he struggled to command his curveball, the Sox had him experiment with a slider late last season. He took to the pitch quickly, and the mechanics and grip of that pitch allowed him to reclaim his 12-to-6 curveball.

Britton, who sat at 90-95 mph with his fastball and topped out at 96, is currently working with all four of his pitches (fastball, slider, curve, change), and believes that a low- to mid-80s slider with tilt represents a distinct offering from his high-70s curve.
