Tate (forearm) was activated from the 10-day injured list Monday.
Tate was struck in the arm by a line drive early in camp and spent the early part of the season in the injured list. He's expected to fill a relief role upon his return to the club and will be looking to improve upon his numbers from his 21-inning debut last season in which he struggled to a 6.43 ERA. Evan Phillips was optioned in a corresponding move.
