Miley was traded to the Red Sox on Wednesday in exchange for Allen Webster, Rubby De La Rosa, and a minor league prospect, FOX Sports' Ken Rosenthal reports. Miley will head to Boston after being a regular in the Diamondbacks' rotation the last three seasons. His ratios declined each of the last two seasons, but he struck out a career-high 183 batters last year, and will face AL hitters regularly for the first time in his career. He will likely slot in at or near the top of the Red Sox's rotation.
