The Red Sox have designated righty Roman Mendez for assignment, the club announced. His roster spot was needed to clear space for outfielder Chris Young, whose signing was made official.
Mendez, 25, was claimed late last season from the Rangers. He has tallied 46 2/3 MLB innings over the last two years, working to a 3.09 ERA but posting a mediocre strikeout-to-walk rate of 6.2 K/9 against 4.8 BB/9. Mendez spent most of 2015 at Triple-A Round Rock, working to a 3.45 ERA with 9.1 K/9 against 3.8 BB/9 over 57 1/3 frames.
