Santana (illness) is absent from Sunday's lineup against Kansas City.

Santana left in the fifth inning of Saturday's game due to an illness, and he will sit for the series finale Sunday. Jose Miranda will start at first base while Ryan Jeffers serves as the designated hitter.

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

Diaz started the previous four games and will receive a day off after going 7-for16 with two homers, five RBI and three runs during that span. Jonathan Aranda will receive a start at first base in the series finale at Baltimore.

The Red Sox designated Dalbec for assignment Sunday, Pete Abraham of The Boston Globe reports.

Dalbec has been with Triple-A Worcester since June 22. Since then, he has slashed .260/.345/.475 with 11 home runs, 43 RBI and a 36.9 percent strikeout rate across 249 plate appearances with Worcester. Dalbec has hit 47 home runs for the Red Sox over the past four seasons, and if he elects to move on from the organization, he should get interest from teams looking for a lefty-hitting first baseman.

Soderstrom (wrist) started at first base and played six innings in a rehab game for Triple-A Las Vegas on Saturday, going 0-for-3.

Soderstrom had the night off Friday after making his rehab-assignment debut as the designated hitter Thursday and slugging a two-run home run. The rookie took the important step of getting on the field Saturday, and he should continue ramping up his participation level in coming days with Las Vegas as he works to shake the rust from a near two-month layoff.

Vaughn went 3-for-4 with a two-run home run in Saturday's 7-5 loss to the Red Sox.

Vaughn opened the scoring with a first-inning homer. This was Vaughn's second multi-hit effort in the last three games, following a stretch in which he went 2-for-28 over eight contests. The first baseman is up to a .240/.295/.399 slash line with 17 homers, 62 RBI, 51 runs scored, 28 doubles and two stolen bases across 131 contests as one of the White Sox's top hitters this year.

Diaz went 3-for-4 with a home run, a walk, two RBI and an additional run scored in Saturday's 7-1 win over the Orioles.

Diaz led off the game with a 440-foot blast off Zach Eflin and later added an RBI single in the eighth frame. Over his past 10 games, the 33-year-old has tallied five multi-hit efforts while homering four times and driving in eight runs. On the season, he's batting .279 with 14 home runs, 64 RBI and 51 runs scored across 567 plate appearances.

Santana left Saturday's game against the Royals due to an illness, Dan Hayes of The Athletic reports.

Santana went 0-for-2 before exiting in the fifth inning of Saturday's contest. Kyle Farmer replaced Santana at first base.

Casas is out of the lineup for Saturday's game against the White Sox.

Casas will dodge a matchup with southpaw Garrett Crochet on Saturday. In his place, Connor Wong will play first base and bat sixth.

Gurriel isn't in the Royals' lineup for Saturday's game against the Twins.

Gurriel has gotten off to a solid start through his first four games with the Royals, going 3-for-9 with two RBI and a run scored. He'll get a breather Saturday while Robbie Grossman serves as Kansas City's designated hitter and bats eighth.

Singleton isn't in the Astros' lineup for Saturday's game against the Diamondbacks, Chandler Rome of The Athletic reports.

Singleton will get a breather Saturday after going 3-for-15 with two home runs and three RBI across his last five games. In his absence, Yainer Diaz will cover first base while Victor Caratini starts behind the dish and bats sixth.
