Littell was optioned to Triple-A Sacramento on Tuesday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Littell has been a decent bullpen option this season with a 3.44 ERA, 1.32 WHIP and 25:16 K:BB over 34 innings, but he'll head to the minors Tuesday. The right-hander could rejoin the Giants later in the year when additional bullpen depth is needed.
