Red Sox trade for Diamondbacks SP Wade Miley

The Boston Red Sox have acquired starting pitcher Wade Miley in a trade with the Arizona Diamondbacks. In return, the Red Sox are sending pitchers Allen Webster and Rubby De La Rosa and infielder Raymel Flores to the Diamondbacks.

The deal was rumored throughout the week, with the two teams reportedly discussing the trade on Tuesday night before reportedly reaching an agreement in principle on Wednesday.

Miley, 28, went 8-12 with a 4.34 ERA last season, the worst of his three full years in the majors. In 2012, Miley was an All-Star and finished second in the National League Rookie of the Year voting after going 16-11 with a 3.33 ERA.

Miley is eligible for arbitration and will be under team control through 2017.

De La Rosa and Webster were originally acquired by the Red Sox in the 2012 Josh Beckett-Adrian Gonzalez-Carl Crawford trade with the Los Angeles Dodgers. De La Rosa, 25, made 18 starts and one relief appearance for Boston last season, going 4-8 with a 4.43 ERA over 101.2 innings. Webster made 11 starts, going 5-3 with a 5.03 ERA.

The trade continues a busy offseason for the Red Sox, who signed Pablo Sandoval and Hanley Ramirez as free agents last month and were in the running for free-agent pitcher Jon Lester, who ultimately signed with the Chicago Cubs.
