The Athletics reinstated Jimenez (oblique) from the 15-day injured list Sunday.
Jimenez landed on the shelf in late June due to an oblique strain, but he's ready to rejoin the A's after a four-game rehab assignment. The right-hander has a save and five holds with a 3.04 ERA, 1.44 WHIP and 21:18 K:BB across 23.2 innings this season.
