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

Kayfus will hit the bench for a fourth consecutive game, with the Guardians having faced three lefties and one righty during that stretch. The 24-year-old looks like he'll have to settle for a limited role as a fourth outfielder and backup first baseman with the hot-hitting Angel Martinez having taken control of a regular spot in the lineup.

Walker (leg) will start at first base and batting cleanup Sunday against the Mariners, Chandler Rome of The Athletic reports.

Walker was held out of the starting nine for Saturday's 8-7 loss after he was spotted taking part in pregame exercises to test out his leg, though the Astros never officially announced that he was dealing with an injury. The veteran first baseman's return to the lineup for Sunday's series finale indicates that the issue was a minor concern. After a disappointing first season in Houston in 2025, Walker has started 2026 strong with three home runs and a .986 OPS through 15 games.

Harris is out of the lineup for Sunday's game against the Royals.

The left-handed hitter will take a seat for the second time in the series against another southpaw in Noah Cameron. Harris has started three straight games against right-handed pitching and could have a hold on a strong-side platoon role until Chicago gets Kyle Teel (hamstring) or Austin Hays (hamstring) back from the injured list. A promotion for top prospect Sam Antonacci could also block Harris' path to regular playing time in left field.

Mountcastle (foot) is out of the lineup for Sunday's game against the Giants, Jake Rill of MLB.com reports.

Mountcastle exited Saturday's 6-2 win due to left foot pain and had been scheduled to undergo an MRI on Sunday. The Orioles should have a better idea of whether Mountcastle will require a stint on the injured list after the testing.

Torkelson went 1-for-2 with two walks and an RBI in Saturday's 6-1 win over the Marlins.

Torkelson is still searching for his first home run of 2026, but he has at least been performing a bit better at the plate recently. Over his last five games, the first baseman is batting .333 with an .863 OPS, and he's walked four times versus only three strikeouts. The power should come for Torkelson as long as he's seeing the ball well, and the Tigers figure to remain patient with their slugger, who delivered 31 long balls during the 2025 regular season.

Mountcastle (foot) is slated to have an MRI on Sunday, Andy Kostka of TheBaltimoreBanner.com reports.

Mountcastle exited Saturday's 6-2 win over San Francisco after stumbling and diving as he approached second base on a double. He was immediately replaced by a pinch runner and exited the field with a trainer. Clarity about Mountcastle's injury and a timeline for his return to action could come once the results of his imaging are in.

Walker performed leg exercises on the field prior to Saturday's game against Seattle to determine his availability, and he isn't included in Houston's starting lineup, Brian McTaggart of MLB.com reports.

Walker was looked at by a trainer during Friday's game after running out a double play, per Chandler Rome of The Athletic, and he's beginning Saturday's contest on the bench. Houston hasn't announced whether Walker is dealing with an injury or if his exclusion from the lineup is precautionary, nor is it clear if he'll be available off the bench. Isaac Paredes is starting at first base Saturday in Walker's absence.

Mountcastle, who was pulled from Saturday's game against the Giants after hitting a double in the second inning, is said to be dealing with left foot pain, Jake Rill of MLB.com reports.

Mountcastle was replaced on second base by Dylan Beavers after the former hurt himself on a stumble and dive toward second base after hitting a double. It's not clear how serious Mountcastle's injury is, but he exited the field with a trainer by his side.

Mountcastle was removed from Saturday's matchup versus San Francisco after appearing to hurt himself while diving into second base on a hit, Roch Kubatko of MASNSports.com reports.

Mountcastle got the start at DH on Saturday -- just his second start over Baltimore's past four games -- and doubled in his first at bat in the bottom of the second inning, However, he stumbled while running to second base and appeared to hurt himself while sliding into the bag. Mountcastle was subsequently removed, and Dylan Beavers entered as the pinch runner. Details about Mountcastle's injury should emerge during or after the contest.

Casas (knee) will be "out a while" with what is now being described as a likely oblique issue, Chris Cotillo of MassLive.com reports.

Casas opened the season on the 10-day injured list while continuing to rehab from left knee surgery. He had been swinging a bat but was shut down in early April with what was initially deemed a left intercostal strain. Casas tried to resume swinging less than a week later, but that didn't go well, and he was consequently sent in for an MRI. While Boston is still waiting for the results of that imaging, manager Alex Cora said Saturday that the organization is now treating the issue "like an oblique, rib injury." Cora added, "He's going to be out for a while but we're still waiting for the news from the doctor."
