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.

Freeman went 3-for-8 with a two-run home run, an additional run, a double and two walks across both games of Tuesday's doubleheader split with the Rockies.

Freeman did most of his work in the nightcap, when he padded an already substantial Dodgers lead with a two-run homer in the sixth inning. The superstar first baseman added a double in that contest, his league-leading 58th two-bagger of the campaign. He needs two more doubles to become the first MLB player since 1936 to collect 60 in a campaign. Freeman has complemented the two-bagger bonanza with 27 homers, 98 RBI, 127 runs, 22 stolen bases and a .333/.410/.564 slash line.

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.

Votto is not in the lineup for Wednesday's game against the Guardians.

It's the first time since Sept. 6 that Votto is not in the starting lineup versus a right-hander. Christian Encarnacion-Strand is covering first base for the Reds, and Jake Fraley will be in the designated-hitter spot.

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.

Gurriel is starting at first base and batting sixth in the first game of Wednesday's doubleheader versus the Mets, Jordan McPherson of the Miami Herald reports.

Jorge Soler is getting a start in right field and Josh Bell will be the designated hitter, opening up first base for Gurriel. It's the first start since Sept. 16 for the 39-year-old.

Hoskins (knee) took batting practice and ran the bases at Citizens Bank Park on Tuesday, MLB.com reports.

Hoskins hit a few home runs during batting practice and has been taking 70-to-75 swings per day, according to Phillies manager Rob Thomson. "It sure looks good," Thomson said Tuesday. While Hoskins still looks like a long shot to return from ACL surgery for the postseason, the team isn't ruling it out if they make a deep run. "We're looking more toward the World Series, if he were to get there," Thomson said. Hoskins is set to hit free agency this offseason.

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.

Montero went 3-for-7 with a home run and two RBI across both games of Tuesday's doubleheader against the Dodgers.

Montero was one of the few bright spots of the second game of the doubleheader when he slugged his eighth home run of the season. He's held a consistent role between first base and designated hitter since Sept. 1, and he's maintained a .299 average with three home runs, nine RBI and 14 runs scored across 77 at-bats. He has a 29.9 percent strikeout rate in that span, but it's been a relatively encouraging close to the campaign for Montero.
