Wheeler (shoulder) is slated to have thoracic outlet decompression surgery Sept. 23, Charlotte Varnes of The Athletic reports.

Wheeler underwent a procedure in mid-August to remove a blood clot near his shoulder, and he's set for a second (and more significant) procedure after being diagnosed with venous thoracic outlet syndrome. The veteran hurler is expected to need six to eight months to recover from the upcoming surgery, which means that he may not be ready for Opening Day next season. However, if all goes well moving forward, Wheeler should be able to return to the mound sometime during the first half of the 2026 campaign.

Lowder (oblique) will begin a rehab assignment at Triple-A Louisville on Saturday.

Lowder has sat out the entire season while working his way back from injuries to his forearm and, more recently, his oblique. The Reds haven't ruled out a late-season return for the 23-year-old righty, though he would need a relatively quick rehab assignment to have time to make an appearance for the Reds before the end of the season.

Senga struck out eight batters and allowed one earned run on three hits and no walks over six innings in a start for Triple-A Syracuse on Friday.

The 32-year-old right-hander signed off on being optioned to the minors last week to try and get right after stumbling to a 6.56 ERA, 1.71 WHIP and 35:22 over his last eight starts and 35.2 innings for the Mets. Senga's first turn in the Syracuse rotation provided a great deal of hope that he might still be able to boost New York's fading playoff hopes, as he fired 52 of 74 pitches for strikes in an efficient performance. Per Jared Greenspan of MLB.com, the Mets' original plan was to have Senga make two starts at Triple-A to get used to some mechanical tweaks before a return to the majors was considered, but with Jonah Tong having been pummeled by the Rangers on Friday and the Mets' lead over the Giants for the final wild-card spot in the National League having slipped to half a game, the organization may not be able to afford that kind of patience. Absent the Mets moving a player to the injured list to create a spot on the 28-man active roster for him, however, Senga isn't eligible to return to the Mets until Sept. 20.

Waldrep (4-1) took the loss Friday as Atlanta got routed 11-3 by the Astros, coughing up eight runs on eight hits and two walks over 4.2 innings. He struck out four.

The 23-year-old right-hander finally got saddled with his first loss of the season in his eighth appearances (seventh start), and Waldrep gave up more runs Friday than he had in the prior seven trips to the mound combined as his ERA soared from 1.33 to 2.78 as a result of the disastrous performance. After throwing 103.1 innings across all levels in 2024 and 137 frames between Triple-A and majors this season, Waldrep may be running out of gas -- he hasn't been able to complete six innings in any of his last four starts. He's scheduled to make his next outing on the road next week against the Nationals.

Tong (1-2) took the loss Friday, surrendering six runs on four hits and three walks over two-thirds of an inning as the Mets fell 8-3 to the Rangers. He struck out one.

The 22-year-old rookie couldn't escape the first inning, walking two of the first three batters he faced, and Tong may have been feeling jitters in a high-profile matchup against former Mets ace Jacob deGrom. Tong was the victim of bad luck as much as his control problems, however, as he gave up three opposite-field singles on bloops and flares -- none hit harder than 89.1 mph -- before a well-placed double by Michael Helman into the left-field corner with an exit velocity of just 81.5 mph chased the right-hander from the game. Tong sports an unsightly 8.49 ERA, 1.71 WHIP and 13:7 K:BB through his first three starts and 11.2 big-league innings, and with Kodai Senga looking sharp in his first Triple-A start Friday, the Mets may make a change in their rotation as they try to desperately cling to a wild-card spot. If he gets another turn, Tong is currently set to make his next start at home next weekend against the Nationals.

Triple-A Albuquerque placed Feltner on its 7-day injured list July 30 due to right shoulder inflammation, Thomas Harding of MLB.com reports.

Feltner produced a serviceable 4.49 ERA and 1.34 WHIP across 30 starts with the Rockies in 2024, but he's been limited to just six starts with the big club in 2025 after a back issue kept him on the shelf for all of May and June before he was optioned to Triple-A on July 4 at the conclusion of his rehab assignment. He had continued to pitch out of the Albuquerque rotation following his activation, but after walking nine batters in just 3.2 innings in a July 24 appearance, Feltner was shut down again with a new injury. The Rockies haven't indicated where Feltner currently stands in his recovery from the shoulder issue, but with just eight games left on Albuquerque's schedule, the 29-year-old righty is most likely done for the season.

Alcantara (9-12) came away with the win in Friday's 8-2 victory over Detroit, surrendering two runs on four hits while striking out eight batters over seven innings. He did not issue a walk.

Alcantara gave up a solo shot to Riley Greene in the fourth inning and threw a wild pitch in the seventh to allow another run to score. However, a three-homer effort from Miami's offense gave the right-hander more than enough run support to claim his first win of September. Alcantara's 5.53 ERA for the season still doesn't look pretty, but he's begun to look more like his old self recently while posting a 2.48 ERA and 0.78 WHIP alongside a 41:6 K:BB across 40 frames over his last six starts. He'll have plenty of momentum on his side during what figures to be a favorable matchup against Colorado next week.

Burrows is slated to start Sunday's game against the Nationals in Washington.

After making a pair of relief appearances Aug. 30 and Sept. 3, Burrows slotted back into a starting role Tuesday against the Orioles, though the Pirates continued to manage his workload in his first full season back from April 2023 Tommy John surgery. In his start versus Baltimore, Burrows struck out six and generated 14 whiffs while permitting one run on two runs and one walk, but he was lifted after just four innings and 56 pitches. Braxton Ashcraft ended up piggybacking Burrows and covered three innings out of the bullpen, but with Ashcraft slated to start Monday's series opener versus the Cubs, Burrows could have a slightly longer leash Sunday while he makes his second straight start.

Buehler (8-7) earned the win Friday, allowing one run on five hits and one walk over five innings against Kansas City. He struck out three.

The veteran right-hander was assigned to Triple-A Lehigh Valley after signing with the Phillies in late August, and he delivered one of his better starts of the season in his team debut after a tumultuous run in Boston. Buehler will be part of the Phillies' six-man rotation for the final weeks of the regular season, and Friday's showing was a good step toward potentially earning a spot on the playoff roster. His 5.29 ERA and 1.54 WHIP across 117.1 innings between Boston and Philadelphia remain unsightly, however.

Keller did not factor into the decision Friday, allowing two runs on four hits and one walk over 5.1 innings in a 6-5 loss against Washington. He struck out four.

The right-hander appeared on his way to his seventh victory of the season with a 3-0 lead through five frames, but he was charged with a couple runs on three hits in the sixth before the Pittsburgh bullpen faltered an inning later. Keller entered the All-Star break with a 3.48 ERA across 119 innings, but he has a 5.73 ERA in 10 starts since the midseason break.
