The Athletics designated Urshela for assignment Friday.

After slashing .238/.287/.326 with 20 RBI and 10 runs scored through 197 plate appearances on the year, Urshela will lose his place on the Athletics' 26-man and 40-man rosters. He'll be replaced on the big club by Brett Harris, who was recalled from Triple-A on Friday. The A's also claimed Jared Shuster off waivers from the White Sox to round out the 40-man.

The Athletics recalled Harris from Triple-A Las Vegas on Friday.

Harris will make his 2025 MLB debut if he gets into a game, as he's spent the entire season at Triple-A. The 27-year-old has slashed .282/.369/.500 with 12 home runs and seven stolen bases across 252 plate appearances for Las Vegas. He'll take Gio Urshela's spot on the active roster and should have an opportunity for regular playing time while Max Muncy (hand) is sidelined.

Manager Alex Cora said Friday that Mayer (wrist) has begun taking dry swings, but it's unclear if he will return this season, Mac Cerullo of the Boston Herald reports.

Mayer's recovery from right wrist soreness has been slow, even after undergoing an anti-inflammatory injection at the start of August. The 22-year-old began playing catch this week and has now begun swinging a bat. While it didn't initially seem like the injury would threaten to sideline Mayer for the rest of 2025, Cora was non-committal when asked about the rookie's return this season.

Seattle optioned Mastrobuoni to Triple-A Tacoma on Friday.

Mastrobuoni will yield his spot n the 26-man roster to Luke Raley, who was activated off the injured list in a corresponding move. Mastrobuoni went hitless in two at-bats during his 16-day MLB stint.

Ramirez went 3-for-4 with an RBI, three runs scored and two steals in Thursday's 9-4 win over the Marlins.

Ramirez has been on a run-scoring binge, crossing home plate 15 times over the last 14 contests. He's tied for 10th in MLB and leads the Guardians with 79 runs scored this season, giving him a shot to score 100 runs for a second straight season.

Caminero went 2-for-5 with a home run, a double, two total runs and three total RBI in Wednesday's 8-2 win against the Athletics.

Caminero began his day with a first-inning, run-scoring double and added a two-run blast to left field in the ninth frame. The All-Star third baseman has been swinging a hot and powerful stick of late, notching multiple hits in five of his past seven games and clubbing six homers during that span while batting .414 (12-for-29). Caminero is third in the American League with 34 homers on the season after entering the campaign with just seven big-league homers across 50 career contests.

McKinstry is not in the lineup for Wednesday's contest versus the White Sox.

McKinstry has gone 0-for-6 with five strikeouts in the first two games of the series and is slashing only .172/.243/.328 in the second half, so he'll get a day off to regroup. Colt Keith is at third base and batting leadoff for the Tigers.

Ramirez 3-for-4 with a double and two solo home runs in Tuesday's 4-3 win over the Marlins.

His second long ball of the night was a game-winner, as he took Calvin Faucher deep in the eighth inning to snap a 3-3 tie. It was Ramirez's second multi-homer performance of the season and the 27th of his career, moving him into first place on Cleveland's all-time list ahead of Jim Thome and Albert Belle. Ramirez broke out of a 2-for-25 slump with the effort, but he's been mostly locked in since the All-Star break, slashing .289/.385/.611 over his last 23 contests with seven homers, four steals, 13 RBI and 22 runs.

Vargas went 0-for-3 with two walks and a run scored Tuesday against the Tigers.

Vargas returned from the injured list Tuesday after a minimum stint. He hit sixth in the lineup and played first base while scoring in the eighth inning on an RBI single from Edgar Quero. Vargas figures to be a regular in the lineup moving forward.

Bregman went 2-for-5 with a two-run home run and an additional run scored during Tuesday's 14-1 win over Houston.

Bregman has homered in back-to-back games against his former team, with Tuesday's long ball coming at the expense of Shawn Dubin. Bregman's now up to 16 home runs on the year. In his last eight games, Bregman is 11-for-28 (.393) with eight runs scored, six RBI and a 7:3 BB:K.
