Guerrero (elbow) threw a 25-pitch live batting practice session Aug. 12 and could soon head out on a rehab assignment, MLB.com reports.

Guerrero is eligible to be activated from the 60-day injured list later this week, but he'll need additional time to complete a rehab assignment before making his return to the Boston bullpen. Before landing on the shelf June 28 due to a right elbow strain, Guerrero compiled a 4.15 ERA, 1.33 WHIP and 10:14 K:BB in 17.1 innings over 13 appearances.

The Athletics announced Aug. 12 that Holman (finger/shoulder) has advanced to gripping drills and is building toward a throwing progression, MLB.com reports.

Holman has been stuck on the injured list since June 19, and though he's no longer shut down from activity, he remains without a clear timeline for a return. The reliever was initially placed on the shelf due to rotator cuff tendinitis in his right shoulder, but the Athletics are now classifying his injury as a strained right middle finger.

Gomez did not factor into the decision Sunday against Minnesota, allowing two hits and three walks over 4.2 scoreless innings. He struck out six.

While Gomez was able to hold the Twins scoreless, he was unable to qualify for a win after throwing 89 pitches before departing with two outs in the fifth inning. Still, the 25-year-old Gomez has been solid overall in three starts since shifting into the rotation, allowing four earned runs across 14.2 innings while striking out 16. He's currently lined up to face the Yankees at home his next time out.

Estevez earned the save in Sunday's 10-8 win over the Tigers, striking out one in a perfect ninth inning.

Estevez has been perfect in five straight appearances while posting a 1.29 ERA in his last seven innings. He's up to 34 saves on the year, tied with Robert Suarez for the MLB lead, with a 2.67 ERA, 1.08 WHIP and 48 strikeouts across 57.1 innings.

The Angels placed Mederos on the 15-day injured list Sunday due to right shoulder inflammation.

Mederos made his third start of the season in Saturday's 12-1 loss to the Cubs and was the pitcher of record after yielding six earned runs on four hits and two walks across four innings. Following the game, Mederos told Jeff Fletcher of The Orange County Register that his shoulder felt off toward the end of his start, and the Angels decided to deactivate him while they look to glean more information about the injury. Mederos is expected to undergo an MRI in the coming days before the Angels provide a potential timeline for his return. Caden Dana delivered a 13-strikeout gem in his most recent start with Triple-A Salt Lake on Friday and could be a top candidate to step in for Mederos the next time his turn in the rotation comes up.

The Angels placed Fulmer on the 15-day injured list Sunday due to right elbow inflammation.

According to MLB.com, Fulmer sustained the injury while throwing a changeup during his relief appearance in Saturday's 12-1 loss to the Cubs. Before departing, Fulmer was charged with six earned runs on seven hits and one walk over 1.1 innings, bringing his ERA up to 5.83 for the season. Though the Angels are labeling his injury as inflammation, Fulmer will undergo further testing as the team looks to rule out a more significant issue to his elbow, per Jeff Fletcher of The Orange County Register.

The Angels recalled Silseth from Triple-A Salt Lake on Sunday.

Though he's made most of his appearances in the big leagues the past three seasons as a starter, Silseth transitioned to a full-time relief role at Triple-A in late July after returning from a stint on the 7-day injured list. He's thrived out of the bullpen for Salt Lake, tossing 8.2 scoreless frames while striking out 13 over his last nine appearances. The right-hander will likely be deployed by the Angels in lower-leverage spots initially but could work his way up the bullpen depth chart quickly if he excels early on with the big club.

The Blue Jays recalled Schultz from Triple-A Buffalo on Sunday.

The 27-year-old righty has produced a 4.56 ERA and 1.44 WHIP over 23.2 innings in 12 appearances (two starts) with Toronto this season. He'll provide the Blue Jays with a multi-inning bullpen option heading into Sunday's game against the Marlins.

The Blue Jays optioned Fluharty to Triple-A Buffalo on Sunday.

Fluharty pitched the previous two days, so the Blue Jays will send him to Buffalo in favor of a fresh bullpen arm in Paxton Schultz. Over 51 appearances with the big club this season, Fluharty has netted a 4.94 ERA, 1.27 WHIP and 48:24 K:BB in 47.1 innings while collecting four wins, four holds and one save.

The Astros recalled Rooney from Triple-A Sugar Land on Sunday.

Houston optioned AJ Blubaugh to Triple-A to make room for a fresh bullpen arm. Acquired from the Marlins on Aug. 3, Rooney will be joining the big club for the second time this month after failing to make his MLB debut during his initial stint with Houston.
