Smith signed a one-year contract with the Red Sox on Wednesday, Gabrielle Starr of the Boston Herald reports.

Smith slashed .263/.337/.375 across 89 plate appearances with the Rays' Triple-A affiliate while on a minor-league deal. He was released by Tampa Bay earlier on Wednesday and will now join the Red Sox on a major-league deal to help make up for the loss of Triston Casas (ribs). Smith will likely end up splitting time with Garrett Cooper (wrist) at first base, replacing Bobby Dalbec.

Singleton went 1-for-4 with a three-run home run, a walk and two runs scored in Tuesday's 10-9 win over the Guardians.

Singleton was somewhat surprisingly in the lineup and starting at first base despite the promotion of Joey Loperfido. Singleton began his day with a walk before coming around to score in the third inning, and he followed that up one plate appearance with his first home run of the campaign. He has the chance to see additional at-bats at first base with Jose Abreu demoted to the minors and Loperfido picking up at least some starts in the outfield. However, for Singleton to log regular plate appearances, he'll need to improve upon his .239/.327/.348 line.

Loperfido went 1-for-5 with two RBI and a run scored Tuesday against the Guardians.

Loperfido was officially called up Tuesday for his big-league debut and started in left field in place of Chas McCormick (hamstring). Loperfido flew out in his first plate appearance, but he delivered a two-RBI single with the bases loaded in the fourth inning for his first big-league hit. The Astros have been somewhat unclear on their plan to use him in the short term, but there are regular plate appearances available with Jose Abreu away from the team.

Naylor went 1-for-4 with a three-run home run and an additional run scored during Tuesday's 10-9 loss to the Astros.

Naylor launched his seventh home run of the campaign and scored multiple times for the second time this season. Even with Naylor's long ball, he's batting 3-for-22 (.136) over his last six games. However, he's added a pair of stolen bases and has struck out four times to three walks during that stretch.

Dalbec entered Tuesday's 4-0 win over the Giants in the bottom of the fifth inning after Garrett Cooper was hit by a pitch on the wrist. Dalbec was hit by a pitch and subsequently stole a base in his lone plate appearance.

The early word on Cooper's injury is a wrist contusion, and it's unclear how much time he'll need to make a full recovery. The development puts Dalbec back in the mix for more playing time; he had been the primary first baseman prior to Boston acquiring Cooper last week.

The Astros selected Loperfido's contract from Triple-A Sugar Land, and he's starting in left field and batting seventh Tuesday against the Guardians.

The 24-year-old will receive his first taste of the big leagues as veteran Jose Abreu heads to the minors amid a horrid start to the campaign. Loperfido should see time at both first base and in the outfield but may not immediately have an everyday role, as GM Dana Brown said he doesn't think it would be "fair" to use Loperfido as the regular first baseman right away.

Astros general manager Dana Brown said Tuesday that Abreu is not with the MLB club and will be optioned to the Astros' rookie-level Florida Complex League affiliate Wednesday, Chandler Rome of The Athletic reports.

The 37-year-old has struggled to a .099/.156/.113 slash line in 77 plate appearances through the first month of the season, so he'll voluntarily head to Houston's FCL affiliate in an attempt to "get some at-bats and his timing back right," per Brown. It will be the first time in the minors for Abreu, as he immediately joined the White Sox after coming up from Cuba in 2014 and has never had a minor-league rehab assignment.

Walsh signed a minor-league contract with the White Sox on Tuesday, LaMond Pope of the Chicago Tribune reports.

Walsh elected free agency after being removed from the Rangers' 40-man roster earlier this month. The 30-year-old hit just .226/.317/.321 with one home run through 60 plate appearances with Texas. He'll go to extended spring training for now before eventually reporting to Triple-A Charlotte, where he'll give the White Sox some veteran protection at first base.

Santana went 1-for-4 with a two-run home run during Monday's 3-2 win over the White Sox.

Santana went yard once again Monday, tallying his fourth long ball in his last five games with a two-run homer off Garrett Crochet in the second inning. He's been on an absolute tear in his last five outings, batting .333 with 10 RBI. Despite the hot streak, Santana owns a poor .185/.265/.348 slash line through 102 plate appearances.

Schanuel isn't in the starting lineup for Monday's matchup versus Philadelphia, Rhett Bollinger of MLB.com reports.

Schanuel went 2-for-3 with a solo home run Sunday in a loss to the Twins, but he'll head to the bench Monday while Brandon Drury gets a start at first base. This will be Schanuel's first time out of the starting lineup since April 19.
