Garton was recalled from Triple-A Durham on Wednesday, Bill Chastain of MLB.com reports.
The bullpen was taxed Tuesday, going 6.1 innings in relief of Matt Andriese (groin), so the Rays added reinforcements in the form of Garton and Austin Pruitt. Garton gave up six runs in 3.2 innings during a prior stint with the major-league team earlier this year, but he's allowed just one run while striking out 24 in 15.1 frames with Durham.
