The Giants recalled Beck from Triple-A Sacramento on Sunday.
He'll join the bullpen as a replacement for Ryan Borucki, whom the Giants designated for assignment. Beck made two scoreless relief appearances in the majors earlier this month but has spent most of the season at Sacramento, where he's turned in a 3.91 ERA, 1.35 WHIP and 23:9 K:BB across 23 innings. He'll handle a low-leverage role while he's up with San Francisco.
