Gage was recalled from Triple-A Sugar Land on Monday, Chandler Rome of The Athletic reports.
The 30-year-old lefty has a 1.83 ERA, 1.07 WHIP and 20 strikeouts in 19.2 frames in the big leagues, but he has been up and down between the majors and minors this season. Look for Gage to work in low-leverage situations.
