Pratto is not in the lineup for Wednesday's game at Detroit.

Salvador Perez will take a turn at first base as Logan Porter handles the catching duties for the visiting Royals. Pratto, 24, has posted a disappointing .231/.309/.357 batting line across 91 major-league games this season.

Mountcastle (shoulder) was activated from the 10-day injured list ahead of Wednesday's game against the Nationals, Roch Kubatko of MASNSports.com reports.

Mountcastle is not in the Orioles' lineup Wednesday versus Washington, but he should be available off the bench and is expected to make a full return in Thursday's series opener against the Red Sox. The 26-year-old wound up missing exactly 10 days because of left shoulder inflammation.

Calhoun is absent from the lineup Wednesday against the Reds.

Calhoun connected for a two-run homer Tuesday, but he'll grab a seat in Wednesday's series finale with the Reds throwing left-hander Andrew Abbott. Jose Ramirez is filling the DH role as Steven Kwan, Myles Straw and Ramon Laureano start across the outfield.

Diaz (hamstring) remains out of the lineup Wednesday at Boston.

Diaz made an early exit from Sunday's series finale against the Blue Jays due to right hamstring tightness and is now on the bench for a second straight game. Isaac Paredes will play first base for the Rays on Wednesday versus the Red Sox as Junior Caminero covers third base.

O'Hearn is absent from the lineup for Wednesday's game versus the Nationals, Roch Kubatko of MASNSports.com reports.

The Nationals are throwing left-hander Patrick Corbin, so O'Hearn will take a seat. Anthony Santander is getting a start at first base, and Aaron Hicks will patrol right field.

Calhoun went 1-for-4 with a two-run home run in Tuesday's 11-7 loss to the Reds.

Calhoun's blast put the Guardians ahead 5-4 in the third inning of the back-and-forth game. He's hitting just .171 with three homers and 10 RBI over 22 games in September, a notable decline from his work in August that helped to earn him steady playing time. The veteran is at a .222/.288/.386 slash line with six homers, 25 RBI, 18 runs scored and no stolen bases over 42 contests this season.

France went 2-for-4 with a solo home run and an additional run scored in Tuesday's 6-2 win over the Astros.

France logged his third multi-hit effort in his last four games. More importantly, he hit his first homer since Aug. 15, a span of 36 games in which he batted a paltry .220 and slugged just .252. Despite his poor hitting lately, France has maintained a fairly steady spot in the Mariners' lineup. He's at a .251/.336/.365 slash line with 11 homers, 57 RBI, 77 runs scored, a stolen base and 32 doubles through a career-high 153 games this season.

Solano went 4-for-4 with one double and three runs scored in Tuesday's victory over the Athletics.

Solano broke out of his slump Tuesday, scoring thrice and reaching safely in all five plate appearances after entering the contest with one hit across his last eight games (24 at-bats). Through 129 games thsi season, Solano is slashing .286/.371/.401 with 41 runs scored, 38 RBI and a 22.3 percent strikeout rate.

Schanuel (knee) isn't in the Angels' lineup Tuesday against Texas, Erica Weston of Bally Sports West reports.

Knee tightness caused Schanuel to be removed from Monday's game during the seventh inning, and the Angels will give him an extra day to heal Tuesday. Brandon Drury will shift to first base in Schanuel's absence, allowing Eduardo Escobar to serve as the Halos' designated hitter.

Rizzo (concussion) said Monday that he is feeling significantly better and expects to have a normal offseason, Gary Phillips of the New York Daily News reports.

Rizzo's 2023 season officially ended Sept. 12 when he was moved to the 60-day IL. He had been diagnosed with post-concussion syndrome in early August and has shown gradual improvement since then, though it wasn't enough for him to return during the current campaign. Nonetheless, Rizzo said Monday that he is feeling "a lot clearer and pretty strong," adding that he's continued to stay active during his time on the injured list. The veteran first baseman indicated that he may start his offseason training program earlier than usual due to his shortened campaign and stated that he expects to be a full-go for spring training next year.
