Mountcastle is out of the lineup for Sunday's game against the Red Sox.

Mountcastle looks to be getting a rest day after starting six of the Orioles' last seven games, including the second leg of Saturday's doubleheader. Emmanuel Rivera will fill in at first base for Mountcastle, who is slashing .266/.286/.342 with no home runs so far in May.

Santana was scratched from the lineup for Sunday's game against the Tigers due to left leg tightness, Tim Stebbins of MLB.com reports.

The Guardians are labeling Santana's removal from the starting nine as a precautionary measure, in part due to the quick turnaround from Saturday night's game and Sunday's early start time. Kyle Manzardo will step in at first base and bat fifth against Detroit ace Tarik Skubal.

Sogard is out of the lineup for Sunday's game against the Orioles.

Sogard will get a breather after starting each of the last five games and going 6-for-17 with two doubles, three runs and two RBI. The 27-year-old has been seeing most of his action at first base since being promoted from Triple-A Worcester on May 10, but he could get occasional starts at third base while Alex Bregman (quadriceps) is on the shelf.

Athletics manager Mark Kotsay said that Kurtz was removed in the 10th inning of Saturday's 9-6 loss to the Phillies due to a left hip flexor injury, Martin Gallegos of MLB.com reports.

Kurtz went 2-for-3 with two walks, a run and an RBI before he was lifted for a pinch runner in the bottom of the 10th. Kostay labeled Kurtz as day-to-day, noting that the star rookie is set to be evaluated by the medical staff Sunday before a decision on his availability for the series finale is made.

Toro went a combined 1-for-5 with two solo home runs across Saturday's doubleheader split against the Orioles.

Toro started at first base in Game 1 and slugged a fifth-inning solo shot to right-center field. He began the nightcap on the bench but entered as a defensive replacement in the eighth. Toro belted another solo blast in the ninth frame in his lone Game 2 plate appearance, accounting for Boston's only run of the contest. The 28-year-old's opportunities have been sporadic this season, and he's started just once in the team's past six games, but Toro could start to see a bit more playing time with Romy Gonzalez (quad) suffering a setback in his recovery earlier in the week and Alex Bregman (quad) landing on the 10-day IL on Saturday.

Solano went 2-for-3 with a walk in Saturday's 2-1 loss to Houston.

Solano made his fifth start at first base among 12 appearances in the month of May, but he remains without an RBI since April 17. Over his last 15 outings (30 at-bats), the veteran infielder is batting an empty .267 with just two extra-base hits. The absence of Luke Raley (oblique) hasn't translated to a boost in playing time for Solano, who should continue to function on the short side of a platoon with the lefty-hitting Rowdy Tellez at first base.

Guerrero went 1-for-4 with a solo home run in Saturday's 3-1 loss to the Rays.

Guerrero supplied the Blue Jays' only run of the game in the sixth inning, when he took Shane Baz deep to left field for a solo home run. Guerrero is up to seven home runs on the season, three of which have come over his last nine games. He has slashed .282/.400/.462 with 17 runs scored, four home runs and nine RBI over 95 plate appearances since the beginning of May.

Goldschmidt went 3-for-4 with a walk, a steal, an RBI single and two runs scored in Saturday's 13-1 win over the Rockies.

Goldschmidt came around to score twice during the Yankees' 10-run fifth inning and contributed to the rout with an RBI single to center field. Goldschmidt has logged three hits in a game seven times this season and has 21 multi-hit performances. The veteran first baseman is slashing .344/.399/.492 with four steals, five home runs and 27 RBI over 209 plate appearances this season.

The Red Sox transferred Casas (knee) to the 60-day injured list Saturday.

Casas underwent surgery in early May to repair the ruptured patellar tendon in his left knee and will aim to return in 2026. The move corresponds with the Red Sox selecting Marcelo Mayer's contract from Triple-A Worcester while placing Alex Bregman (quad) on the 10-day injured list.

Sogard will start at third base in the afternoon game of Saturday's doubleheader against the Orioles, Christopher Smith of MassLive.com reports.

Sogard steps in for Alex Bregman, who was removed from Friday's contest with right quad tightness. It's unclear if Bregman could be available for the second game of the doubleheader, or if manager Alex Cora will make do with Sogard or another body.
