Mountcastle (hamstring) is not expected to be activated from the 60-day injured list until next week's series in Philadelphia, Jake Rill of MLB.com reports.

Mountcastle has played three rehab games with Triple-A Norfolk and is eligible for activation Wednesday, but the Orioles will give him a little more time following a nearly two-month long absence due to a right hamstring strain. With Ryan O'Hearn a candidate to be traded ahead of Thursday's deadline, Mountcastle and Coby Mayo could be in line to share the first-base and designated-hitter spots for the Orioles down the stretch.

Guerrero went 2-for-4 with a walk and a two-run home run in Monday's loss to the Orioles.

He took Zach Eflin deep in the third inning to tie things up at 3-3, but Baltimore pulled away after that. Guerrero has hit safely in 10 straight games, slashing .463/.532/.780 over that span with three of his 15 homers on the season, as well as four doubles, 10 RBI and 12 runs.

Naylor went 2-for-4 with a solo home run, an additional run scored and a stolen base in a 3-1 victory versus the Athletics on Monday.

Naylor got the scoring started in the contest, belting a 405-foot solo blast in the second inning. The long ball was his first since making his Mariners debut July 27 as well as his first overall since July 7 (a span of 15 games). Naylor also continued to run wild Monday -- he swiped his fourth bag in his past three contests and has already blown past his previous career-high mark with 15 thefts on 17 attempts this season.

Mayo went 3-for-4 with a home run and two RBI in Monday's 11-4 win over the Blue Jays.

Mayo recorded the first three-hit effort of his career, highlighted by a 413-foot solo blast in the second inning. He's impressed since the All-Star break, going 7-for-17 with two homers, five RBI and five runs scored over seven games. The 23-year-old is slashing .240/.318/.406 with three long balls, 14 RBI, 13 runs scored and one steal across 107 plate appearances, and his role moving forward may hinge on what the Orioles decide to do at this week's trade deadline.

Torkelson went 2-for-4 with an RBI in Monday's 5-1 win over the Diamondbacks.

Torkelson has collected a hit in eight of his 11 games following the All-Star break, and he's tallied three multi-hit performances during the stretch. The slugger is now batting a solid .274 this month with six home runs and 13 RBI across 23 contests. Torkelson is showing some consistency during a bounceback campaign after he struggled to find his footing last year. His OPS is up from .669 during the 2024 regular season to .825 so far in 2025.

Kurtz (lower body) is starting at first base and batting second against the Mariners on Monday.

Kurtz was held out of Sunday's series finale against the Astros while managing some lower-body fatigue. The 22-year-old first baseman has put it together at the plate and is in the midst of a 13-game hitting streak, highlighted by his 6-for-6 performance with four home runs, eight RBI and six runs against Houston on Friday.

Naylor went 1-for-4 with two stolen bases in Sunday's 4-1 loss to the Angels.

Naylor has literally hit the ground running to begin his time with the Mariners, swiping three bags over his first three games since he was traded from the Diamondbacks. He has gone 3-for-11 with a walk and four strikeouts in those contests. Overall, the first baseman is at a .292/.359/.442 slash line with 14 steals, 11 home runs, 59 RBI, 50 runs scored, 19 doubles and one triple through 96 games. He has quickly settled into an everyday role, as expected, with his new team.

Tellez is out of the lineup for Sunday's game against Atlanta.

The left-handed-hitting Tellez had started at first base in each of the Rangers' previous four matchups against right-handed pitchers, but he'll hit the bench Sunday against Atlanta righty Bryce Elder. With the Rangers getting another left-handed bat in Joc Pederson (hand) back from the injured list Sunday, Tellez may have lost hold of his strong-side platoon role.

Athletics manager Mark Kotsay said that Kurtz is out of the lineup for Sunday's game against the Astros due to lower-body soreness/fatigue, Martin Gallegos of MLB.com reports.

Kurtz went 2-for-4 with a walk and a run in Saturday's 5-1 win after his historic 6-for-6 performance Friday that included four home runs, eight RBI and six runs. The rookie will get a well-deserved break Sunday, with Kotsay characterizing Kurtz's absence from the lineup as more of a rest day, even though the skipper conceded that Kurtz was dealing with some fatigue. Kurtz will still be available off the bench Sunday and should return to the lineup for Monday's series opener versus the Mariners.

Goldschmidt is out of the lineup for Sunday's game against the Phillies.

Goldschmidt will be on the bench for the third time in the Yankees' last four matchups, this time against Zack Wheeler. For the season, Goldschmidt is slashing just .246/.292/.332 in 276 plate appearances against right-handed pitching, and he could continue to cede more starts in those matchups to Ben Rice, who has produced a 131 wRC+ versus righties.
