Atlanta claimed Diaz off waivers from the Dodgers on Sunday, David O'Brien of The Athletic reports.

The right-hander was designated for assignment by the Dodgers on Thursday, and it's not a surprise he was claimed off waivers, given his previous success in the majors. Diaz has struggled to a 7.80 ERA in 15 outings in the big leagues with the Dodgers and Reds this season, and he hasn't been much better at the Triple-A level with a 6.08 ERA. He will report to the major-league club.

Wentz (5-6) took the loss Sunday against the Mariners, allowing eight runs on eight hits and a walk across 2.1 innings. He struck out two.

It was a rough day for Wentz, who's now given up 19 runs in just 16.1 innings over his last four starts. Overall, the left-hander sports a 5.12 ERA with a 1.31 WHIP and 49 strikeouts across 51 innings with Atlanta this year. Wentz will look to get on track in his next outing, tentatively scheduled to come next week at home against the Astros.

The Diamondbacks activated DeSclafani (thumb) from the 15-day injured list Sunday.

DeSclafani has been on the shelf since mid-August with right thumb inflammation, and he threw 30 pitches in his most recent bullpen session. The veteran right-hander had made a few trips through the rotation before suffering the injury. Considering the number of pitches he threw in the bullpen session and Nabil Crismatt's recent success, DeSclafani could be moved to the bullpen. However, a six-man rotation remains a possibility. Reliever Bryce Jarvis was optioned to Triple-A Reno in a corresponding move.

The Diamondbacks optioned Jarvis to Triple-A Reno after Saturday's game against the Red Sox.

Jarvis will lose his spot on the active roster as Anthony DeSclafani (thumb) is reinstated from the injured list. Jarvis allowed four runs without recording an out Saturday. He appeared in three games during his latest MLB stint, yielding seven runs across 6.1 innings.

Phillips will serve as an the Marlins' opening pitcher for Sunday's game against the Phillies, Daniel Alvarez-Montes of ElExtraBase.com reports.

Phillips made seven starts for Philadelphia in 2024, but he's been deployed exclusively as a reliever during his first season in Miami. Though he's in line for his first start of 2025 while taking on his former team, Phillips isn't expected to cover much more than an inning or two before turning the game over to the bullpen. Sunday had been Adam Mazur's turn in the rotation, so Mazur could be deployed in bulk relief behind Phillips.

The Mets optioned Herget to Triple-A Syracuse on Sunday.

Herget will head back to Syracuse after a four-day stint in the big leagues. He appeared in two games during that stretch, allowing three runs across 2.1 innings Tuesday before pitching 1.2 scoreless frames Saturday. Herget has a 2.00 ERA in 27 innings with Syracuse this season.

The Mets optioned Suero to Triple-A Syracuse on Sunday.

Suero joined the big-league club Friday after being claimed off waivers from Atlanta on Thursday. He'll now head to Syracuse without making his Mets debut. The 33-year-old reliever logged a 1.35 ERA in 46.2 innings with Atlanta's Triple-A affiliate earlier this season.

The Mets reinstated Garrett (elbow) from the 15-day injured list Sunday.

Garrett had been on the shelf since Aug. 25 due to inflammation in his right elbow. The 32-year-old reliever has been cleared to rejoin the active roster after a brief minor-league rehab assignment, during which he threw a scoreless inning with one strikeout for Double-A Binghamton. Garrett has a 3.61 ERA in 52.1 innings with the Mets this season.

O'Brien (3-0) struck out one in a scoreless frame and was credited with a win in Saturday's victory over the Giants.

O'Brien missed more than a week of action with right shoulder discomfort, but he showed no ill effects Saturday, displaying his normal velocity and needing only eight pitches to retire the Giants in order in the top of the ninth. The reliever picked up his third win of the season after the Cardinals rallied for three runs to walk it off in the bottom of the frame. As long as he stays healthy, O'Brien will remain in the late-inning mix for St. Louis.

Ashcraft (forearm) played catch Saturday, MLB.com reports.

Ashcraft was placed on the 15-day injured list Aug. 27 due to a right forearm strain, which an MRI confirmed to be inflammation in a muscle near his wrist. The next step for Ashcraft is to throw a side session Sunday and then face live hitters.
