To help fill the void created when Jon Lester was traded away, the Red Sox brought back Justin Masterson and inserted him into the starting rotation. They're looking for an improvement over his numbers last year, which included career worsts in ERA (5.88) and WHIP (1.63). Masterson will get his first start today as the Red Sox wrap up an interleague series with the Phillies. To get our pick for this game and the full MLB schedule, click on the Baseball icon above.
