The Red Sox have designated lefty Drake Britton for assignment, the club announced (via Tim Britton of the Providence Journal, on Twitter). His roster spot will go to the just-signed Alexi Ogando, whose signing was made official.
Britton, 25, has seen 27 2/3 innings of action at the MLB level over the last two years, working to a 2.93 ERA with 6.8 K/9 and 2.9 BB/9. But he spent most of 2014 at Triple-A, where he struggled to a 5.86 earned run mark in 58 1/3 frames.
With Robbie Ross added to the bullpen mix and Craig Breslow already on hand, Boston apparently felt it could stand to sacrifice some southpaw depth. It surely did not help that Britton is out of options. That fact will limit interest around the league, though he seems a likely candidate to be claimed or traded out of limbo.
