Alvarez was removed from Wednesday's game against the Padres after getting hit in the head by a foul ball in the fifth inning, Anthony DiComo of MLB.com reports.

Alvarez managed to finish the inning after the foul tip deflected off his catcher's helmet, but he didn't come back out on defense for the start of the sixth. The Mets will likely evaluate him for a concussion and may offer an update on his status shortly. Meanwhile, Luis Torrens stands to benefit from increased playing time behind the plate.

Pages is out of the lineup for Wednesday's game against the Marlins.

Pages will get a breather for the series finale while Yohel Pozo receives a turn at catcher Wednesday. Though the Cardinals appear to have ruled out Ivan Herrera from playing behind the plate anytime soon, Pages' grasp on the No. 1 catcher role appears to be slipping. He's getting on base at a .147 clip and hasn't produced an extra-base hit in 10 games since the All-Star break, with his offensive struggles opening the door for Pozo to pick up more playing time.

Hicks is out of the lineup for Wednesday's game against the Cardinals.

Hicks will head to the bench for the series finale in St. Louis after he went hitless with five strikeouts in 12 at-bats while starting in each of the previous three contests. With Hicks sitting out Wednesday, Agustin Ramirez will start at catcher and Kyle Stowers will serve as Miami's designated hitter.

Contreras went 2-for-4 with two solo home runs in Wednesday's 10-3 loss to the Cubs.

Contreras snapped a power drought with his first home run since June 14 in the first inning, then added another in the fourth. It marked the fifth multi-homer game of the catcher's career and put an exclamation point on a strong three-game set against the Cubs that featured three extra-base hits, three RBI and six runs scored. On the season, he's slashing .250/.348/.363 with eight long balls, 45 RBI, 56 runs scored and five steals across 443 plate appearances.

Diaz is out of the lineup for Wednesday's game against the Mets.

Though he'll take a seat in the series finale, Diaz may have at least temporarily overtaken Martin Maldonado as the Padres' top catcher. Diaz started in each of the Friars' last three games, going 3-for-12 with a double, five RBI and two runs.

Adams is out of the lineup for Wednesday's game against the Astros.

Adams will receive a routine day off for the afternoon contest after he started in each of the Nationals' previous three games. Drew Millas will replace Adams behind the dish and will bat eighth.

Baldwin is out of the lineup for Wednesday's game against the Royals.

The left-handed-hitting Baldwin will take a seat for the second time in the series while the Royals send another lefty starter (Angel Zerpa) to the bump. Since Zerpa is serving as an opener and may not cover more than an inning or two, Baldwin could be a candidate to replace Sean Murphy at catcher or Marcell Ozuna at designated hitter once Zerpa exits the contest.

Marchan will start at catcher and bat ninth in Wednesday's game against the White Sox.

He'll draw his 20th start of the season while top backstop J.T. Realmuto gets a breather for the day game after a night game. Marchan will head into Wednesday's contest with a .175/.268/.254 slash line to go with one home run, six RBI and five runs over 72 plate appearances on the campaign.

Realmuto is absent from the lineup for Wednesday's contest against the White Sox.

Realmuto will get a breather in Wednesday's matinee after starting each of the previous eight contests. Rafael Marchan will fill in behind the plate and will bat ninth for the Phillies.

Herrera is out of the lineup for Wednesday's game against the Tigers.

Herrera will hit the bench for the fourth time in five games and appears to be falling into the shorter side of a timeshare at catcher with James McCann, who started in three of the previous four contests. Both McCann and Herrera will be left out of the lineup for the series finale in Detroit, however, as Arizona hands Adrian Del Castillo -- who had been serving as the club's primary designated hitter -- his first start of the season at catcher.
