Gage (elbow) threw a bullpen session Monday, Susan Slusser of the San Francisco Chronicle reports.
Gage landed on the 15-day injured list with a left elbow strain July 4 and was transferred to the 60-day IL on Aug. 2. The southpaw will continue building up in hopes of rejoining the Giants' bullpen before the end of the season. In 27.1 innings on the campaign, Gage owns a 5.60 ERA, 1.65 WHIP and 22:17 K:BB.
