The Boston Red Sox have sent starting pitcher Wade Miley and Jonathan Aro to the Seattle Mariners in exchange for pitchers Carson Smith and Roenis Elias. It was first reported by Ken Davidoff of the New York Post with other details by Jon Heyman of CBS.

Miley heads to the west after only a single season in Boston. The starting pitcher went 11-11 over 32 starts with a 4.46 ERA, 1.368 WHIP and 147 strikeouts in 193.2 innings. Over his career, mostly with the Arizona Diamondbacks, Miley is 49-46 with a 3.95 ERA.

The former 1st round pick (43rd overall) was acquired by the Red Sox during last year’s Winter Meetings in exchange for pitchers Rubby De La Rosa and Allen Webster and infielder Raymel Flores. In February, Boston signed Miley to a three-year $19.25 million contract extension.

The Red Sox will also send relief pitcher Aro to the Mariners. Aro has spent most of his career in the minors, but made three appearances for Boston this season.

In return, the Red Sox get relief pitcher Smith and starter Elias. Over his career, Smith is 3-5 with 13 saves, a 2.07 ERA, 0.970 WHIP and 92 strikeouts in 70 innings. Elias comes to Boston with a 15-20 record in two seasons with the Mariners. Over his career he has posted a 3.97 ERA, 1.308 WHIP, and 240 strikeouts in 279 innings.

This move is the second move this December for the Red Sox focused on pitching. Boston acquired starting pitcher David Price last week and move Miley out of the starting rotation while adding Smith to the bullpen.

Smith averaged 11.8 strikeouts per nine innings last year and is not eligible for arbitration until after 2017 season.
