The Athletics recalled Johnson from Triple-A Las Vegas on Saturday.

Johnson carries a hefty 7.29 ERA and 2.00 WHIP through 21 innings in the majors this season, but he'll rejoin the Athletics' bullpen after giving up just one run in 5.1 Triple-A innings since being sent down to Vegas on Aug. 19. Kade Morris was optioned to Triple-A in a corresponding move.

With Jeffrey Springs back from the 15-day injured list, Johnson is losing his spot on the 26-man roster. Acquired from the Phillies in exchange for Colby Thomas two weeks ago at the trade deadline, Johnson surrendered seven runs on 10 hits and three walks with six strikeouts across 4.2 innings out of the bullpen for the Athletics.

Johnson has yet to find much success in the majors, putting up a 7.18 ERA and 37:21 K:BB over 31.1 frames covering parts of three seasons. However, he's a hard thrower who holds a 2.17 ERA and 40:11 K:BB across 29 frames this season at Triple-A Lehigh Valley. Johnson might get a chance to pitch high-leverage innings as part of a patchwork Athletics bullpen.

With Brad Keller surely out for the season after being diagnosed with a UCL tear, Johnson will come up from the minors to replenish the Phillies' bullpen depth. The 27-year-old owns an 8.20 ERA and 1.71 WHIP over 26.1 innings in his MLB career and hasn't been much better in the big leagues this year, conceding nine earned runs in just 11.1 frames. He'll likely be limited to a low-leverage relief role.

The 27-year-old righty will be pushed back to Triple-A to make room for Brad Keller's (forearm) return from the injured list. Johnson made eight appearances with the Phillies after being called up June 18, and he surrendered six earned runs and posted a 10:7 K:BB in 7.2 innings while up in the majors. Although he carries a 7.15 ERA in the big leagues, he remains an option to return to Philadelphia later in the year if its bullpen depth is tested.
