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."

Lowe went 1-for-4 with a three-run double during the Reds' 7-3 win over the Angels on Saturday.

Lowe gave the Reds a 4-0 lead in the first inning after a bases-clearing, three-run double off George Klassen (finger). Lowe has been limited to a bench role early on in the season, and he doesn't have a clear path to regular playing time unless Sal Stewart were to miss time.

Murakami went 0-for-3 with a walk and two strikeouts during the White Sox's 2-0 loss to the Royals on Saturday.

Murakami opened his first MLB season strongly with three home runs in three consecutive games and was up to four homers and seven RBI through eight contests. However, he has cooled off at the plate of late, going 1-for-20 with six walks, three runs scored and nine strikeouts in his past seven games. These types of growing pains are to be expected for Murakami, but he'll have plenty of runway to work on his game after signing a two-year, $34 million contract with the White Sox in December.

Walker isn't in the lineup for Saturday's game versus the Mariners, Chandler Rome of The Athletic reports.

Walker went 0-for-3 with a walk and a run scored in Friday's series opener, breaking what had been a six-game hitting streak. He'll get a day off Saturday while Isaac Paredes gets the nod at first base and bats third.

Polanco (Achilles) will start at designated hitter and bat third against the Athletics on Saturday.

Polanco has been in and out of the Mets' lineup recently with Achilles problems and sat out the Mets' last two games following his Achilles bursitis diagnosis, but he's seemingly feeling well enough to return to the starting nine Saturday. The 32-year-old has slashed .200/.289/275 across his first 45 plate appearances with New York.

Smith went 3-for-4 with two runs scored and two RBI in Friday's win over the Guardians.

The 30-year-old has had an impressive start to the season as a strong-side platoon option at designated hitter. Through 10 games, Smith is slashing .357/.400/.571 with two homers, eight runs and eight RBI, but his playing time could take a hit once Sean Murphy (hip) comes off the IL.
