Gonzales underwent flexor tendon repair surgery on his left forearm Friday, Andrew Destin of the Pittsburgh Post-Gazette reports.

Gonzales is expected to need 12 months before returning to play, meaning he could be sidelined for the entire 2025 campaign. The Pirates are expected to decline his $15 million team option for next season.

Manager Dave Roberts said Glasnow felt discomfort in his right elbow Friday while warming up for a simulated game, Fabian Ardaya of The Athletic reports.

Glasnow was slated to face live hitters for two or three simulated innings, but he instead returned to the clubhouse after warming up. The 31-year-old right-hander will get additional testing on his elbow to provide some clarity on his chances of returning before the end of the regular season, per Juan Toribio of MLB.com. Glasnow has been on the 15-day injured list since Aug. 16 due to tendinitis in his right elbow.

The Mariners recalled Hancock from Triple-A Tacoma on Friday.

Since being optioned to Triple-A in early July, Hancock has posted a 4.50 ERA and 1.40 WHIP alongside a 30:21 K:BB across 50 innings. He'll now rejoin the Mariners' rotation to replace Luis Castillo (hamstring), who landed on the injured list Tuesday. Hancock's first MLB start in over two months will come against a Rangers offense that has produced a .723 OPS since the start of September.

The Rockies optioned Gordon to Triple-A Albuquerque on Friday.

Gordon was called up to make a spot start Wednesday and yielded seven runs in 3.1 innings against the Tigers. He'll return to Albuquerque on Friday, giving way to Austin Gomber (paternity list) on the 26-man roster. Gordon has an 8.65 ERA in 34.1 innings for the Rockies this season.

Olson (shoulder) is trending towards a return early next week in Kansas City, Chris McCosky of The Detroit News reports.

McCosky hints than an announcement will come Saturday, and given that Tarik Skubal has been confirmed to start Wednesday, that leaves Monday or Tuesday as potential dates for Olson to make his return to the rotation. He struck out five across three scoreless frames in his rehab start Tuesday for Triple-A Toledo.

Gomber was reinstated from the paternity list Friday. He'll start Friday's game against the Cubs.

As expected, Gomber will rejoin the team to make the start Friday. The left-hander has been impressive across his last five starts, logging a 3.00 ERA and a 1.06 WHIP with a 23:7 K:BB across 33 innings. Tanner Gordon was optioned to Triple-A Albuquerque in a corresponding move.

Skubal (hand) will start Wednesday's game in Kansas City, Chris McCosky of The Detroit News reports.

All the tests checked out on Skubal's bruised non-throwing hand, but he will end up getting an extra day of rest in between his starts. Evan Woodbery of MLive.com notes that the Tigers could squeeze three more starts total out of Skubal, with him staying on normal rest to start Sept. 24 at home against Tampa Bay and then working the final day of the regular season against the White Sox. Detroit is 2.5 games out of the final wild-card spot in the AL however, and if the team has nothing to play for by that point, Skubal could be shut down or have a restricted pitch count for his final outing.

Stroman is moving to the bullpen and will be available in relief Sunday against the Red Sox, Bryan Hoch of MLB.com reports.

The Yankees will go with a five-man rotation for the next week or two, and Luis Gil and Clarke Schmidt have moved ahead of Stroman in the hierarchy. Stroman figures to serve as a long reliever, but he could get a spot start in the final week if the Yankees need to set up their rotation for the postseason.

Glasnow didn't complete his scheduled simulated game Friday, Jack Harris of the Los Angeles Times reports.

Glasnow went straight to the clubhouse after warming up in the bullpen instead of facing hitters. It's unclear why he couldn't complete the session, but it doesn't bode well for his ability to return before the end of the regular season. Glasnow hasn't thrown for the Dodgers since Aug. 11 due to elbow tendinitis.

Eder was recalled from Triple-A Charlotte prior to Friday's game against the Athletics.

Once a promising prospect in the Marlins' system, Eder had Tommy John surgery in 2021 and hasn't recaptured his pre-surgery combination of wipeout stuff and starter-level command. He has a 9.87 ERA and 1.99 WHIP in 34.2 innings across nine starts for Charlotte. Eder will work in one-inning relief appearances, per Scott Merkin of MLB.com.
