Stock was recalled from the Red Sox's alternate training site Tuesday.

EDGE Analysis

Stock was claimed off waivers by Boston at the end of July but will join the active roster after Jeffrey Springs was optioned to alternate camp. Stock made 10 appearances in the majors with the Phillies last season, posting a 10.13 ERA and 2.06 WHIP over 10.2 innings. He should pitch mainly out of low-leverage situations with the Red Sox.
