The Rays designated Bard for assignment Monday.
He'll cede his spot on the 40-man roster to lefty reliever Garrett Cleavinger, whom the Rays acquired from the Dodgers on Monday. Before he was optioned to Triple-A Durham over the weekend, Bard made eight appearances out of the Tampa Bay bullpen this season and submitted a 1.93 ERA, 1.00 WHIP and 8:7 K:BB across 14 innings.
