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."

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.

Manzardo went 1-for-4 with a solo home run in Friday's 11-5 loss to Atlanta.

Manzardo popped his first home run of the season in the fourth inning. The Guardians expected to see Manzardo take a next step in 2026, but he's off to a slow start. He entered Friday batting .086 (3-for-35) with one RBI and a 34.1 strikeout percentage.

Guerrero went 3-for-5 with two doubles, two runs scored, one steal and an RBI during Toronto's 10-4 win over Minnesota on Friday.

Guerrero notched his first steal of the season in the seventh inning before being brought home on an RBI single by Davis Schneider, and the former drove in a run of his own on a double in the eighth. Guerrero has just one home run through 13 regular-season games, but he currently boasts a .429 OBP.

Diaz went 2-for-4 with a two-run homer during Friday's 5-3 win over the Yankees.

Diaz tied the game at 2-2 in the bottom of the first inning after smacking a two-run homer to right-center field off Luis Gil. It was Diaz's third home run of the season and second since the calendar flipped to April, and he has five multi-hit games early on in 2026. He has gone 19-for-51 (.373) with nine runs scored, 12 RBI and one steal through 13 regular-season games.
