Smith isn't in the lineup for Tuesday's game against the Angels.

Smith will give way to Dalton Rushing behind the plate after the former went 2-for-4 with a run scored during a loss in Monday's series opener.

The Cubs activated Amaya (oblique) from the 60-day injured list Tuesday, Maddie Lee of the Chicago Sun-Times reports.

Amaya has been sidelined since May 25 due to a left oblique strain. With Amaya's return, the Cubs have opted to keep three catchers on the 26-man roster, with Amaya joining Carson Kelly and Reese McGuire. Jon Berti was designated for assignment in a corresponding move. Prior to his injury, Amaya was slashing .280/.313/.505 with four home runs, 25 RBI, 14 runs scored and a 4:22 BB:K across 100 plate appearances. He had been well on his way to a career year at the dish.

Realmuto is not in the lineup for Tuesday's game against the Reds, Lochlahn March of The Philadelphia Inquirer reports.

It's a routine day off for the veteran backstop, as Rafael Marchan will handle catching duties and bat ninth. Realmuto is slashing .273/.325/.393 with 22 doubles, seven home runs, 39 RBI, 41 runs scored, six stolen bases and a 26:94 BB:K across 403 plate appearances this season.

Ruiz remains in concussion protocol but is continuing to take part in baseball activities, Andrew Golden of The Washington Post reports.

While the fact that Ruiz hasn't been shut down from activity is encouraging, the Nationals haven't provided much information regarding the extent of his workouts, nor has the team provided any indication of how close he might be to exiting concussion protocol. Since Ruiz landed on the injured list July 8, the Nationals have turned to Riley Adams as their primary option at catcher.

Fermin went 1-for-4 with a two-run home run in Monday's 4-1 win against San Francisco.

Fermin's hit in the contest was a two-run shot to left field in the seventh inning that gave San Diego a 4-1 lead. The long ball was his first since joining the Padres via trade July 31. Fermin has brought his new team some much-needed consistent hitting from the catcher position -- since the trade, he's batting .370 (10-for-27) with four RBI over eight contests.

McCann is out of the lineup for Monday's game against the Rangers.

After starting behind the plate in three of Arizona's previous four contests, McCann will get a breather as the Diamondbacks kick off a three-game set in Texas. Adrian Del Castilo will handle the catching duties for the Diamondbacks on Monday.

Davis is out of the lineup for Monday's game against the Brewers.

Davis will take a seat for the series opener in Milwaukee after he started behind the plate in three of the Pirates' four games versus the Reds this past weekend. Joey Bart will get the nod at catcher and will bat seventh Monday.

Pozo is not in the lineup for Monday's game versus the Rockies.

Pozo looked like he might be inching ahead of Pedro Pages in the Cardinals' catcher pecking order earlier this month, but it will be Pages behind the dish Monday for the fourth time across the last five contests.

Pages will start at catcher and bat eighth in Monday's game against the Rockies.

With four starts behind the plate in the last five games, Pages appears to have at least temporarily wrested the primary catching gig away from Yohel Pozo. Already regarded as the superior defensive catcher of the two, Pages has helped his case for earning more playing time by running hot at the dish to begin August. Through five games this month, Pages has gone 6-for-16 with two home runs, one double, two walks, six RBI and three runs.

The Rockies designated Nola for assignment Monday.

The Rockies have been carrying three catchers for most of this month, but they will now go back to two backstops as Nola gets booted off the 26-man active roster and 40-man roster. Nola had played sparingly lately and will have the ability to elect free agency if he passes through waivers.
