Jameson underwent an MRI on his right elbow Tuesday after experiencing renewed tightness coming out of his rehab appearance in the rookie-level Arizona Complex League last Friday, Nick Piecoro of The Arizona Republic reports.

Jameson landed on Triple-A Reno's 7-day injured list May 20 due to inflammation in his right elbow, which he previously had surgically repaired in September 2023. After a month of rest and rehab, Jameson was cleared to resumed pitching in games in the ACL last week, but he made just two appearances before suffering a setback. The Diamondbacks haven't revealed the findings of Jameson's recent MRI, but he'll presumably be out of action through at least the All-Star break.

The Diamondbacks are expected to option Morillo to Triple-A Reno on Wednesday, Nick Piecoro of the Arizona Republic reports.

Morillo has made 28 relief appearances for the Diamondbacks this season, posting a 4.01 ERA and 25:13 K:BB across 24.2 frames. He'll be replaced on the roster by Jake Woodford, who will offer the Arizona bullpen more length.

The Reds recalled Zulueta from Triple-A Louisville on Wednesday, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

The Reds and Red Sox will resume a suspended game Wednesday at 2:30 p.m. ET before playing their regularly scheduled contest later in the evening. Zulueta will be available as the 27th man for the latter tilt. He's allowed one run over 2.1 innings covering two relief appearances with the big club this season.

Chafin (hamstring) threw a simulated game before Tuesday's game was postponed due to rain, Mark Zuckerman of MASN Sports reports.

The veteran southpaw has been sidelined since June 8 due to a strained hamstring. Chafin isn't expected to need a rehab assignment, and if he doesn't have any issues following Tuesday's session, he could be activated from the IL later this week.

The Padres recalled Marinaccio from Triple-A El Paso on Wednesday.

Marinaccio will serve as the 27th man for Wednesday's doubleheader in Philadelphia. The right-hander was acquired by the Padres via trade over the offseason and has spent all of this season at El Paso, collecting a 4.70 ERA and 31:13 K:BB over 30.2 frames.

Lee (1-3) took the loss Tuesday, coughing up three runs on two hits and a walk over one-third of an inning as Atlanta fell 4-0 to the Angels.

Entering a scoreless tie in the top of the eighth inning, Lee sandwiched a walk to Taylor Ward between doubles by Mike Trout and Jo Adell to allow the game's first run to score, and after the southpaw got the hook he had to watch Enyel De Los Santos let both inherited runners cross the plate. The earned runs were the first on Lee's ledger since May 25, and while he's worked his way into the saves mix thanks to his 2.37 ERA, 0.92 WHIP and 40:10 K:BB through 38 innings on the season, Tuesday's usage indicates he's still viewed as more of a high-leverage option than a pure ninth-inning closer.

Lucchesi threw a scoreless eighth inning in Tuesday's 8-2 loss to the Diamondbacks, allowing one hit and one walk while striking out three.

Lucchesi retired the first two batters he faced before issuing a walk and surrendering a single. However, he escaped the inning after recording his season-high third strikeout, and he threw 13 of his 21 pitches for strikes. The left-hander has appeared in six games in the 2025 campaign, posting a 4.50 ERA, 1.67 WHIP and 6:2 K:BB across six innings.

The Mets appointed Warren from Triple-A Syracuse to serve as their 27th man for Wednesday's doubleheader with the Brewers. He'll be available for the second game of the twin bill.

Warren has been recalled from the minors for the fourth time this season but is expected to be in line for another abbreviated stay with the big club. He's made just two appearances out of the New York bullpen, tossing 3.1 scoreless innings while striking out three batters.

The Phillies recalled Johnson from Triple-A Lehigh Valley on Wednesday.

Johnson will serve as the 27th man during Wednesday's doubleheader against the Padres. He has made one relief appearance with the big club this season, allowing one run over two innings. Johnson is likely to be sent back to Lehigh Valley following the twin bill.

Bednar gave up a hit and a walk in a scoreless ninth inning Tuesday to record his 12th save of the season in a 1-0 win over the Cardinals.

The veteran closer wrapped up a combined shutout begun by Paul Skenes, but Bednar needed 20 pitches (12 strikes) to get the job done. His control is beginning to waver again, as he sports a 9:4 K:BB over his last six innings, but Bednar hasn't allowed an earned run since May 23 as he continues a remarkable turnaround from a rough 2024 and a demotion to Triple-A Indianapolis early in 2025. He needs four more saves to become the sixth pitcher in history to collect 100 in a Pirates uniform, but with the trade deadline looming, it's possible he gets dealt away before he reaches that milestone.
