Red Sox, Rangers Bolster Their Rotations

The Boston Red Sox have rebuilt their starting rotation this week.

The Red Sox acquired their third starter in two days on Friday, getting lefty Wade Miley from Arizona for righties Rubby De La Rosa and Allen Webster and infielder Raymel Flores. Miley led the Diamondbacks with 183 strikeouts and 201 1/3 innings pitched last season while going 8-12 with a 4.34 ERA.

The trade came a day after the Bosox acquired Rick Porcello from Detroit and signed free-agent right-hander Justin Masterson.
