Boston, MA (SportsNetwork.com) - After being spurned by Jon Lester the Boston Red Sox continued to bolster their rotation, making an official announcement on Friday of the acquisition of Wade Miley from the Arizona Diamondbacks.

The Sox gave up right-handers Rubby De La Rosa and Allen Webster along with minor-league infielder Raymel Flores.

Miley struggled last season, going 8-12 with a 4.34 earned run average in 33 starts. The former No. 1 pick, though, was a 16-game winner in 2012 and accumulated a 38-35 record with a 3.79 ERA over 106 games (102 starts) for the D-backs.

The 28-year-old hurler finished second in NL Rookie of the Year voting in 2012 and was also an All-Star that season for Arizona.

De La Rosa was 4-8 a year ago for Boston with a 4.43 ERA in 19 games, including a career-high 18 starts.

Webster started 11 games for the Red Sox last season and was 5-3 with a 5.03 ERA.

De La Rosa and Webster, of course, were the center pieces for the Red Sox in the blockbuster deal with the Los Angeles Dodgers in August 2012 that saw them surrender Josh Beckett, Carl Crawford and Adrian Gonzalez.

In a separate transaction between the two franchises, the BoSox snagged right- hander Zeke Spruill from the Diamondbacks for minor league pitcher Myles Smith.
