The Red Sox are expected to recall Eaton from Triple-A Worcester prior to Monday's game against the Orioles, Andrew Parker of Beyond the Monster reports.

Boston won't announce the roster move until Monday, but the Wilyer Abreu (calf) could be a candidate to go on the injured list in a corresponding transaction. Eaton has previously seen action in 14 games with Boston this season, slashing .250/.296/.333 with three stolen bases over 27 plate appearances.

The Mariners recalled Mastrobuoni from Triple-A Tacoma prior to Sunday's game against the Mets in Williamsport, Pa.

Seattle is designating Mastrobuoni as its 27th man for the 2025 MLB Little League Classic, so he'll most likely head back to Tacoma once the contest in Williamsport is completed. Mastrobuoni isn't in the lineup for Sunday's contest but is capable of serving as an in-game replacement at multiple infield or outfield positions.

Harris will start at third base and bat eighth in Sunday's game against the Angels.

After going 2-for-6 with two walks, two runs and an RBI in the first two contests of the series, Harris will remain in the lineup for a third straight game since being called up from Triple-A Las Vegas. So long as he continues to deliver productive at-bats, Harris will likely hold down the fort at third base until Max Muncy (hand) is cleared to return from the injured list.

Rengifo is out of the lineup for Sunday's game against the Athletics.

Rengifo will retreat to the bench for the series finale after he had started in eight of the Angels' previous nine contests. Christian Moore will spell him at second base and will bat seventh.

Moncada is out of the lineup for Sunday's game against the Athletics.

After starting in each of the last five games, Moncada will get a breather as the Angels close out their series in Sacramento. Oswald Peraza will step in for Moncada at third base.

Jung is out of the lineup for Sunday's game against the Blue Jays.

Jung will hit the bench after starting the Rangers' last nine games and going 5-for-34 (.147) with a 2:11 BB:K. The freshly recalled Cody Freeman will replace Jung at third base and bat eighth.

Bregman is out of the lineup for Sunday's game against the Marlins.

Bregman will check out of the starting nine for the first time since July 30 in what appears to be a routine day off. Abraham Toro will cover third base in Bregman's stead Sunday.

Caballero went 2-for-4 with a walk, three runs and two stolen bases against the Cardinals in a 12-8 victory Saturday.

Caballero started in right field for the second straight game, as Giancarlo Stanton got another day off. The speedy utility player has taken advantage of the sudden opportunity, reaching base six times over nine plate appearances while swiping four bases. Given that production, he may begin to see his playing time tick up -- in fact, Caballero is back in the lineup Sunday, this time starting at shortstop in place of Anthony Volpe.

McMahon went 1-for-5 with a solo home run in a 12-8 win against St. Louis on Saturday

McMahon extended New York's lead to three runs with his seventh-inning blast. The long ball was the veteran third baseman's first since he was traded from Colorado to the Yankees in late July. In 20 games with his new club, McMahon has slashed .250/.370/.367 with four doubles, seven RBI, eight runs and an 11:20 BB:K.

Mayer will require season-ending surgery on his sprained right wrist, Ian Browne of MLB.com reports.

Shortly after being placed on the 10-day injured list July 25, Mayer received an anti-inflammatory shot, but the rookie's wrist didn't respond as well as the Red Sox had hoped. The 22-year-old has opted for a permanent fix for the injury and is expected to face a three-month recovery, per Mac Cerullo of the Boston Herald. Mayer should be back to full health ahead of spring training, when he'll likely have to compete for a starting role after slashing just .228/.272/.402 with four home runs over his first 44 big-league games.
