The Marlins activated Simpson (elbow) from the 60-day injured list and optioned him to Triple-A Jacksonville on Tuesday.

The left-hander had the elbow issue surface in February and underwent surgery to repair the ulnar nerve in late April, but he's been fully cleared after an eight-appearance rehab assignment. Simpson surrendered six runs with an 11:8 K:BB across 8.2 innings during the rehab stint, so he'll be sent to Triple-A rather than joining Miami's bullpen.

The Marlins claimed Veneziano off waivers from the Royals on Tuesday.

The left-hander was designated for assignment by Kansas City over the weekend, and Miami scooped him up to bolster its bullpen depth. Veneziano has made just two big-league appearances this season and has a 4.80 ERA, 1.47 WHIP and 76:42 K:BB across 31 outings (14 starts) at Triple-A.

The Brewers recalled Peguero from Triple-A Nashville on Tuesday, Adam McCalvy of MLB.com reports.

Peguero has collected a 3.00 ERA and 43:24 K:BB across 48 frames out of the Milwaukee bullpen this season. He'll likely operate as a middle reliever for the Brewers.

The Brewers placed Wilson on the 15-day injured list Tuesday with a right oblique strain, Adam McCalvy of MLB.com reports.

Wilson evidently must have tweaked his oblique at some point during a 3.1-inning relief appearance in Sunday's extra-innings loss to the Reds. He will be eligible to return Sept. 17, but it's not yet clear whether he will have a chance to be ready by that date.

The Marlins recalled Maldonado from Triple-A Jacksonville on Tuesday.

Maldonado is back with the Marlins after spending the past two months with Jacksonville. The 26-year-old has made 11 appearances in the majors this season and has a 6.23 ERA, 1.54 WHIP and 8:5 K:BB across 13 innings.

The Brewers optioned Hudson to Triple-A Nashville on Tuesday, Adam McCalvy of MLB.com reports.

The move looks odd on the surface, as Hudson boasts a 1.73 ERA and 62:17 K:BB over 62.1 innings this season and had turned in four straight scoreless appearances. However, his velocity has been trending in the wrong direction and the Brewers want to see him get that ticked back up in a less pressurized environment.

The Brewers activated Milner (shoulder) from the 15-day injured list Tuesday, Adam McCalvy of MLB.com reports.

Milner recently made two scoreless rehab appearances to clear the way for his return to the Brewers' bullpen. He has been sidelined since mid-August due to a left shoulder impingement.

The Pirates claimed Wentz off waivers from the Tigers on Tuesday.

Wentz was used as a full-time reliever this season for the first time, holding a 5.37 ERA and 60:27 K:BB over 55.1 innings. The left-hander is under team control through 2029 and is still just 26, so the Pirates thought he was worth a shot. Wentz is out of minor-league options, so he will report directly to the major-league club.

The Marlins claimed Bachar off waivers from the Padres on Tuesday, Jeff Sanders of The San Diego Union-Tribune reports.

Bachar was designated for assignment by the Padres over the weekend without having made an appearance with the big club. The 29-year-old right-hander has collected a 3.89 ERA and 85:32 K:BB over 71.2 innings this season at Triple-A El Paso.

The Marlins outrighted Bermudez to Triple-A Jacksonville on Monday.

Bermudez is no longer on the team's 40-man roster but will remain in the organization as a depth arm. The lefty has been used primarily as a starter at Jacksonville, so he could get stretched back out after most recently working out of the bullpen with the big club.
