Cooper is out of the lineup for Monday's game against the Rays, Chris Cotillo of The Springfield Republican reports.

Cooper has an .860 OPS over his past nine contests but will head to the bench Monday for the second time in Boston's last three games. Connor Wong will rest his legs as the designated hitter while Reese McGuire receives a start behind the plate.

Rivas was designated for assignment by the Cardinals on Monday.

The transaction frees up a spot on the 40-man roster for the addition of Ryan Loutos. Rivas, 27, has slashed just .246/.364/.323 with zero home runs this season at Memphis.

Singleton went 2-for-4 with two RBI and a walk Sunday against the Brewers.

Singleton enjoyed a productive weekend series against the Brewers, collecting five hits across 12 at-bats while scoring a run and driving in two. He's started 18 of the last 19 games since the demotion of Jose Abreu and has hit .230 with a .342 OBP to go along with four homers, 12 RBI and 13 runs scored. Abreu could rejoin the team within the week, but Singleton has made the case to maintain playing time with his production across May.

Torkelson went 1-for-4 with a solo homer and two runs scored in Sunday's 6-4 loss to the Diamondbacks.

Torkelson got the Tigers on the board with a solo blast to center off Jordan Montgomery in the third inning and later scored once more after reaching on a fielder's choice. After not homering in his first 37 games of the season, Torkelson now has three home runs in his last seven games and seems to finally be heating up after a slow start to the year. The 24-year-old also has at least a hit in 12 of 13 games dating back to May 5 and is now slashing .227/.291/.360 with 17 RBI, 21 runs and a 13:43 BB:K in 189 plate appearances.

Cronenworth went 1-for-4 with a two-run homer and a walk in Sunday's 9-1 win over Atlanta.

Cronenworth opened up the scoring with a two-run blast off Bryce Elder in the opening frame for his only hit of the night. Cronenworth owns a 140 wRC+, which is currently third in baseball among all qualified first basemen, behind only Freddie Freeman and Bryce Harper. Cronenworth is putting together an excellent campaign and is currently slashing .275/.344/.485 with eight homers, 30 RBI, 21 runs and a 17:33 BB:K in 192 plate appearances.

Astros GM Dana Brown said Sunday that Abreu could join the team Friday in Oakland, Chandler Rome of The Athletic reports.

The 37-year-old has gone 2-for-9 with a double and a walk in two games with the FCL Astros in the Gulf Coast League, and he's expected to play in a couple more games -- potentially with Triple-A Sugar Land -- this week before rejoining the Astros. Jon Singleton has been operating as Houston's primary first baseman over the past few weeks, and it's unclear if Abreu will immediately reclaim the job once he's called back up.

France is not in the lineup for Sunday's game against the Orioles.

France has a .653 OPS through 15 games in May and will take a seat for Sunday's series finale in Baltimore. Luke Raley will step in at first base and bat cleanup.

Pasquantino is not in the starting lineup for Sunday's game against Oakland.

The lefty-hitting first baseman will begin the game from the dugout as the Royals take on southpaw JP Sears. Salvador Perez will move to first base in place of Pasquantino while Freddy Fermin starts at catcher as Kansas City looks get the sweep against the Athletics.

Smith is not in the lineup for Sunday's matchup against the Cardinals, Chris Cotillo of The Springfield Republican reports.

The lefty-hitting Smith will get a break as Boston takes on southpaw Matthew Liberatore. Garrett Cooper will fill in at first base and bat sixth while Tyler O'Neill moves to designated hitter as the Red Sox look to avoid the sweep in St. Louis.

Lowe went 0-for-4 with two RBI in Saturday's 3-2 extra-innings win over the Angels.

Lowe, who is hitless over his last 13 at-bats, was the late-game hero for the Rangers. He set up extra innings with an run-producing, eighth-inning sacrifice fly, then Lowe was hit by a pitch with the bases loaded in the bottom of the 13th for the walk-off win. The two RBI give him 14 over 26 games.
