Peterson will start Wednesday's game against the Nationals, Andrew Tredinnick of The Bergen Record reports.

The left-hander worked out of the bullpen in his past two appearances -- including one in bulk relief -- but will return to the rotation Wednesday after allowing just one run across seven innings as a reliever. It's been an up-and-down campaign for Peterson, who fired 5.1 scoreless frames in his season debut but followed up with an 8.79 ERA in his next three starts.

Priester (wrist) is scheduled to throw about four innings and 60 pitches in the next start of his rehab assignment Friday, Jack Stern of BrewerFanatic.com reports.

The right-hander made the second start of his rehab assignment Sunday with Triple-A Nashville, throwing 45 pitches across 2.1 frames. Priester has struggled with his command in both rehab outings, issuing three walks in each start while hitting the strike zone with just 30 of 74 total pitches. His sinker also topped out at 92 mph Sunday after averaging 93.2 mph during the 2025 regular season. Priester was expected to require at least three starts in the minors before being activated from the 15-day injured list, but the control and velocity concerns will likely result in a longer rehab stint.

Steele (elbow) suffered a setback in his rehab program and was shut down from throwing Tuesday, Jesse Rogers of ESPN.com reports.

The specifics of the setback aren't yet clear, but any shutdown of more than a few days would likely remove any hope for a return from the 60-day injured list in late May when Steele is first eligible. The left-hander is working his way back from the UCL revision surgery he underwent last April, and his return timeline is now murky.

Atlanta manager Walt Weiss said Tuesday that Waldrep (elbow) will throw a bullpen session in about a week and could be ready to rejoin the team in June, Grant McAuley of the Marietta Daily Journal reports.

Any timetable is approximate, as Waldrep has multiple boxes he needs to check. The young right-hander is working his way back from an arthroscopic procedure Feb. 23 to remove loose bodies from his pitching elbow. Waldrep is currently on the 15-day injured list but could shift to the 60-day IL if Atlanta needs the 40-man roster spot, as he will not be ready to return within the 60-day window.

Atlanta manager Walt Weiss said Tuesday that Strider (oblique) will be activated from the 15-day injured list to make his season debut this weekend in Colorado, Grant McAuley of the Marietta Daily Journal reports.

A report earlier Tuesday said that Strider would make one more rehab start, but that turned out to be inaccurate. Weiss did not reveal the specific day Strider would make his season debut, but if he pitches on four days' rest as he has been on his rehab assignment, he'd start Friday. Strider threw 82 pitches over five innings Sunday with Triple-A Gwinnett, so he should be ready for a relatively normal workload against the Rockies. He's missed the first month of the season with a left oblique strain.

Koenig (elbow) is slated to resume a throwing program Tuesday, Adam McCalvy of MLB.com reports.

Koenig has been shelved for three-plus weeks with a sprained left elbow. Given the nature of the injury, the southpaw reliever will be brought along slowly. The Brewers do not expect Koenig to be ready to return until late May or early June.

The Mets recalled Scott from Triple-A Syracuse on Tuesday.

The right-hander was called up for his season debut last week and was returned to Syracuse after giving up one run on no hits and five walks over 1.1 innings, but he'll make a quick return to the majors with Kodai Senga (back) heading to the injured list. Scott should now get a longer look in the rotation, which was the initial plan before his abbreviated outing forced the Mets to shuffle their bullpen pieces.

The Mets placed Senga on the 15-day injured list Tuesday due to lumbar spine inflammation.

The right-hander has begun the season 0-4 with a 9.00 ERA through his first five starts, and he lasted just 2.2 frames during his most recent outing Sunday versus Colorado. According to Laura Albanese of Newsday, Senga received an epidural and will be shut down from throwing for at least 7-to-10 days. Once healthy and built back up, the Mets are likely to send Senga on what could be a lengthy rehab assignment to try and get him back on track. Christian Scott is poised to claim the open rotation spot after being recalled from Triple-A Syracuse.

The Rockies activated Freeland (shoulder) from the 15-day injured list Tuesday.

Freeland will start Tuesday's game in Cincinnati after missing the last three weeks of action with left shoulder inflammation. The southpaw didn't make any rehab starts prior to being activated, so Freeland could be relatively limited from a workload perspective in Tuesday's outing.

Greene (elbow) is playing catch from 110 feet and is about three weeks away from progressing to bullpen sessions, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

The right-hander underwent surgery on his right elbow in mid-March to remove bone chips, and he moved to the 60-day injured list shortly thereafter. Greene will be eligible to be reinstated in late May but is expected to be out for most of the season's first half. A clearer return timeline should come into focus once he advances to mound work.
