The Marlins will recall Mazur from Triple-A Jacksonville to start Wednesday's game against the Phillies, Christina De Nicola of MLB.com reports.

Mazur made eight starts with the Padres last season, turning in a 7.49 ERA across 33.2 innings before being dealt to Miami in the trade that sent Tanner Scott to San Diego. Mazur has shown improvement at Triple-A Jacksonville this year to the tune of a 3.62 ERA and 1.23 WHIP through 59.2 frames, and he'll now get another opportunity to prove himself in the big leagues. Whether he sticks around in the Marlins' rotation will likely depend on his performance Wednesday and the health of Max Meyer (hip).

Glasnow (shoulder) threw two innings and about 40 pitches in a live batting practice session Tuesday, Jack Harris of the Los Angeles Times reports.

Glasnow has been battling right shoulder inflammation since late April, and he's slowly been making progress in the last couple weeks. The right-hander looked "really good" in the BP session according to manager Dave Roberts, and a minor-league rehab assignment could come in the near future.

The Mets placed Megill on the 15-day injured list Tuesday with a right elbow sprain.

A sprained elbow indicates Megill is dealing with damage to his UCL, but the pitcher said Tuesday that he just has inflammation and no structural damage, per Anthony DiComo of MLB.com. Megill will be shut down for at least 7-to-10 days before ramping back up. The Mets are due to get Frankie Montas (lat) and Sean Manaea (oblique) back soon, but they will need someone else to fill in for Megill later this week in Philadelphia.

The Cardinals activated Hence (ribs) from the 60-day injured list Tuesday and transferred him from Triple-A Memphis to Double-A Springfield.

Hence got a late start to the season due to a right rib cage strain, but he's made five rehab starts, allowing two runs with a 10:7 K:BB over 10.2 innings. The top prospect will now join the rotation at Springfield, where he held a 2.71 ERA and 109:26 K:BB over 79.2 frames in 2024.

Meyer (hip) was spotted playing catch Monday, Christina De Nicola of MLB.com reports.

While Meyer is throwing again, the Marlins haven't indicated when he might be ready to return from the 15-day injured list as he continues to recover from a left hip impingement. A clearer timeline for Meyer's return could come into focus once he reaches the point in his rehab where he's facing hitters in live batting practice.

Mazur has joined the Marlins in Miami and is expected to be recalled from Triple-A Jacksonville to make a start this week during the team's homestand, Craig Mish of the Miami Herald reports.

The Marlins do not have a starting pitcher listed for Wednesday's game against the Phillies, and Mazur would be on six days' rest that day, so he could end up slotting into the rotation for that contest. Mazur has collected a 3.62 ERA and 55:16 K:BB over 59.2 innings this season with Jacksonville. The 24-year-old has a chance to make multiple starts with the big club, although that could depend on when Max Meyer (hip) is ready to return from the injured list.

Double-A Columbus reinstated Hackenberg (undisclosed) from its 7-day injured list Thursday.

Hackenberg has yet to make an appearance since being activated, but he's ostensibly healthy again after missing just over a month of action with an unspecified injury. The 23-year-old righty owns a 7.03 ERA and 1.83 WHIP in 24.1 innings with Columbus on the season.

Fuentes (hand) debuted for Triple-A Gwinnett on Saturday, covering 4.2 innings and striking out six batters while allowing one earned run on three hits and no walks.

Double-A Columbus had placed Fuentes on its 7-day injured list May 27 due to a blister on his pitching hand, but rather than reporting to a lower-level affiliate for a rehab assignment or slotting back into the Double-A rotation, the right-hander was surprisingly moved up to Gwinnett for his first start coming off the injury once he was activated Friday. The 20-year-old turned in an impressive debut for Gwinnett and has continued to elevate his standing as a prospect in 2025 after a strong showing in the Carolina League a season ago.

Dodgers manager Dave Roberts said that Sheehan (elbow) will be activated from the 60-day injured list to start Wednesday's game against the Padres, David Vassegh of AM 570 LA Sports reports.

As expected, Sheehan has received clearance to make his 2025 debut for the Dodgers this week after completely his recovery from May 2024 Tommy John surgery. The right-hander was cleared to kick off his rehab assignment just over a year after the procedure and was sharp over his four outings in the minors, logging a 3.97 ERA, 0.97 WHIP and 21:1 K:BB in 11.1 innings. In his most recent start for Triple-A Oklahoma City last Thursday, Sheehan tossed 3.1 innings and 63 pitches, so he'll likely be operating with a workload restriction Wednesday. While Sheehan should be in line for multiple turns through the Dodgers' rotation, he'll be at risk of a move to the bullpen or a demotion to Triple-A once the likes of Tyler Glasnow (shoulder), Blake Snell (shoulder), Tony Gonsolin (elbow) and Roki Sasaki (shoulder) return from the IL.

Feltner (back) struck out two over 1.2 scoreless innings in a rehab start with the rookie-level Arizona Complex League Rockies on Monday.

It was Feltner's first outing in seven weeks, as he has been shelved since late April with back spasms. The right-hander will be eligible for activation from the 60-day injured list June 28, but he might need more time than that to rebuild his stamina.
