"The Angels' bullpen, owner of the worst second-half ERA in the Majors, will get lefty Scott Downs back from a strained left shoulder on Saturday, with Steve Geltz optioned after Friday night's 12-3 loss to the Rays to create roster space. Walden, meanwhile, could follow on Sunday."
Downs has a 2.57 ERA and 1.23 WHIP over 35 innings. The veteran lefty picked up nine saves in a brief stint as the Halos' closer. Last season, his first with the Angles, Downs had a 1.34 ERA and 1.01 WHIP in 60 games.
Walden, the Angels' closer last season, has a 3.86 ERA and 1.57 WHIP in 28 innings in 2012. The 24-year-old had 32 saves and a 2.98 ERA last season.
Gonzalez speculated that the team could send down either Hisanori Takahashi or Jason Isringhausen to make room for Walden, who is trying to come back from a strained biceps. Downs had a strained shoulder.
