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.

Wentz is starting Sunday's game against the Mariners, Mark Bowman of MLB.com reports.

Spencer Strider was initially penciled in to start Sunday's series finale, but he'll get extra rest while Wentz is pushed up in the rotation. The southpaw has gone fewer than five frames in two of his past three starts, but overall Wentz has been a decent rotation piece for Atlanta with a 3.88 ERA, 1.19 WHIP and 47:17 K:BB over 48.2 innings (nine starts).

Walker (5-5) took the loss and was charged with a blown save against the Cardinals on Saturday, failing to record an out while allowing three runs on four hits and a hit batter.

Called on to protect a two-run lead in the ninth, the right-hander quickly found himself in trouble, surrendering back-to-back singles before plunking Jimmy Crooks to load the bases. Thomas Saggese tied the game with an RBI single, and Jordan Walker followed with a two-run double to left, sealing Walker's fifth blown save of the season in 19 chances. The meltdown also snapped a 10-appearance scoreless streak for the Giants' reliever, who sports a 3.93 ERA, 1.16 WHIP and 55:14 K:BB across 55 innings of work.
