Casali signed a one-year contract with the Giants on Wednesday, Andrew Baggarly of The Athletic reports.

Casali has spent all season with the Cubs' Triple-A affiliate, where he slashed .362/.489/.551 with 11 RBI across 88 plate appearances. He'll now return to San Francisco on a big-league contract to give the Giants depth behind the plate while Patrick Bailey (concussion) and Tom Murphy (knee) are sidelined. Blake Sabol will likely remain the primary option to start at catcher, though Casali could get the nod whenever the Giants are matched up against a left-handed starter.

Amaya is out of the lineup for Wednesday's game against Atlanta, Maddie Lee of the Chicago Sun-Times reports.

Amaya will get a breather after he started at catcher in each of the past three games while going 1-for-9 at the dish. Yan Gomes will fill in for Amaya in Wednesday's series finale.

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

While J.T. Realmuto managed a sore knee, Stubbs started behind the plate in each of the past three games, going 1-for-12 with a stolen base. Realmuto is back in the lineup at catcher Wednesday, and provided he doesn't experience any setbacks with his knee, he should take on a hefty workload moving forward. Prior to Realmuto's recent absence, Stubbs had started in just six of the Phillies' first 40 games of the season.

Realmuto (knee) will start at catcher and bat second in Wednesday's game against the Mets.

Realmuto will re-enter the starting nine after sitting out each of the past three games while managing a sore right knee. Provided he doesn't experience any setbacks in his return to action, Realmuto should resume handling one of the heftier workloads in the league among No. 1 catchers, though it wouldn't be surprising if the Phillies gave him a breather later this week or had him serve as a designated hitter for a game.

Stephenson is out of the lineup for Wednesday's game against the Diamondbacks.

He'll get a breather for Wednesday's afternoon game after starting behind the plate both of the past two days while going 4-for-9 with two doubles and three runs. Luke Maile will get the starting nod behind the plate in the series finale.

Grandal is out of the lineup for Wednesday's game against the Brewers.

Grandal will take a seat for the day game after he started behind the plate in both of the previous two nights, going 1-for-7 with a home run. Joey Bart will replace Grandal on Wednesday as the Pirates' starting catcher.

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

Bethancourt will sit for the second day in a row while Nick Fortes receives another turn behind the plate. Neither Bethancourt (.349 OPS) nor Fortes (.336 OPS) has been productive at the plate this season and both typically bat near the bottom of the order when included in the lineup, making it difficult to extract any fantasy value from the Marlins' catching situation.

Diaz exited Tuesday's 6-3 win over the Padres with left hand soreness and will be held out of the lineup for Wednesday's series finale, MLB.com reports. He struck out in his lone plate appearance on the day.

Diaz exited in the third inning with recurring hand soreness. He's not expected to miss additional time beyond Wednesday's contest, but Jacob Stallings should be behind the dish for Colorado's series finale Wednesday.

The Nationals signed Stubbs to a minor-league contract Tuesday.

Stubbs had been in the Astros system but was released after slashing just .121/.244/.212 over 21 contests between the Double- and Triple-A levels. The 27-year-old will give the Nats some catching depth.

The Giants placed Bailey on the 7-day concussion injured list Tuesday.

Bailey missed the Giants' last two games due to an illness, and he met with a team doctor Monday to determine whether or not his illness was related to the concussion he suffered earlier in May. He'll now return to the 7-day IL and will be eligible to return to action Sunday, though the Giants will likely be more cautious this time around before activating him. Blake Sabol will take over as San Francisco's primary catcher while Bailey is out, and Marco Luciano will come up from Triple-A Sacramento to fill the open roster spot.
