The Giants activated Hicks (shoulder) from the 15-day injured list Saturday, Alex Pavlovic of NBC Sports Bay Area reports.
Hicks landed on the 15-day injured list Aug. 27 due to right shoulder inflammation. He had one rehab outing with Single-A San Jose on Tuesday, when he allowed two unearned runs over two innings while striking out two batters and throwing 27 pitches. Hicks was moved out of the starting rotation to the Giants' bullpen in late July, and in his eight outings since, he's posted a 2.79 ERA and 1.76 WHIP across 9.2 innings.
