Garcia was recalled from the Giants' alternate training site Sunday, Amy Gutierrez of NBC Sports Bay Area reports.
Garcia will be up to bolster the bullpen after manager Gabe Kapler used seven different relievers behind Trevor Cahill on Saturday. The right-hander made nine appearances spanning six innings during his first stint with the big club this season, posting a 7.50 ERA, 2.33 WHIP and 3:2 K:BB.
