Gelof was placed on the 10-day injured list Saturday with a dislocated left shoulder.

It was already reported that Gelof was done for the season after suffering the injury in Friday's game against the Pirates. Max Muncy (hand) was activated from the injured list in a corresponding move and should play regularly in place of Gelof down the stretch.

The Athletics recalled McGough from Triple-A Las Vegas on Saturday.

With Sean Newcomb (elbow) headed for the injured list, the A's will turn to McGough to provide the big club with depth in their bullpen. The 35-year-old has surrendered 10 earned runs in just 12 MLB innings this season but owns a 3.18 ERA through 39.2 frames in the minors. He'll likely be limited to low-leverage work.

Muncy (hand) was activated from the 10-day injured list prior to Saturday's game against the Pirates.

Muncy has been on the shelf since July 21 due to a hairline fracture at the base of the fourth metacarpal in his right hand and did not go on a rehab assignment, instead going through a hitting progression on the side. Zack Gelof (dislocated shoulder) was placed on the injured list in a corresponding move. Muncy should get some starts at third base and the keystone over the final eight games of the season, although he is on the bench Saturday.

Cole is not in Saturday's lineup against the Mariners, Matt Kawahara of the Houston Chronicle reports.

The lefty-hitting Cole heads to the bench even with a righty (George Kirby) on the hill for Seattle. Cole is hitless with four strikeouts and one walk in his last three games after bashing two home runs with seven RBI in his first four big-league games. Cam Smith is starting in right field and batting ninth.

Walker is not in Saturday's lineup against the Mariners, Matt Kawahara of the Houston Chronicle reports.

Walker is hitless with nine strikeouts in his last four games, so he's getting a day to clear his head. Victor Caratini gets the start at first base, batting fifth.

Langford (side) is not in Saturday's lineup against the Marlins.

It was announced Friday that he was being held out with left side tightness, and Langford will miss a second game in a row. Langford is hitting .241 with 21 home runs and 21 steals in 485 at-bats. Michael Helman picks up the start in center field, batting ninth.

The Orioles claimed Hamel off waivers from the Mets on Saturday and optioned him to Triple-A Norfolk, Roch Kubatko of MASNSports.com reports.

A third-round selection in 2021 out of Dallas Baptist, Hamel was moved from a starting role to a relief role this year at Triple-A and made his big-league debut, logging one scoreless inning Wednesday against the Padres before being designated for assignment. Hamel had a 4.61 ERA, 1.37 WHIP and 39:13 K:BB in 41 innings out of the Triple-A Syracuse bullpen.

Wilcox was optioned to Triple-A Durham on Saturday, Marc Topkin of the Tampa Bay Times reports.

The 26-year-old righty made his big-league debut Friday, giving up seven runs (three earned) on four hits and three walks in one inning against the Red Sox. Wilcox has a 3.71 ERA, 1.37 WHIP and 57:27 K:BB in 51 innings as a multi-inning reliever at Triple-A.

Scholtens was recalled from Triple-A Durham on Saturday, Marc Topkin of the Tampa Bay Times reports.

Scholtens, who was claimed off waivers by Tampa Bay on Aug. 4 after he was designated for assignment by the White Sox, has a 4.13 ERA, 1.16 WHIP and 43:9 K:BB in 32.2 innings across seven starts for the Bulls. The 31-year-old righty hasn't pitched in the majors since 2023, when he logged a 5.29 ERA and 1.53 WHIP in 85 innings for the White Sox. He'll likely work as a low-leverage reliever capable of getting more than three outs.

Moore went 1-for-4 with a two-run home run in Friday's loss to Colorado.

Moore put the Angels on the board with a two-run homer that tied the score 2-2 in the second inning. The rookie second baseman has been flashing his power of late, belting three homers in six games since being called back up to the big leagues Sept. 13. His other two hits during that span have been doubles, though he's also struck out nine times in 20 plate appearances.
