Felix Doubront struck out six in five scoreless innings in the Red Sox's 4-2 win over the Twins on Saturday. After experiencing some shoulder soreness early in camp, Doubront rebounded to go 2-2 with a 3.00 ERA in five starts. Last year's terrific strikeout rate makes him an intriguing breakout candidate in 2013. Still, we don't see him as worthy of a spot in mixed-league rotations initially.
