Alvarez isn't in the Mets' lineup for Monday's game against Boston.

Alvarez will sit down for a second consecutive game after going 3-for-16 with two RBI over his last five contests. Luis Torrens will catch instead for Luis Severino and bat ninth.

Herrera is not in the lineup for Monday's game in Milwaukee.

In nine games since Willson Contreras (finger) went on the 10-day injured list, Herrera has started five games at catcher for the Cardinals, while Pedro Pages has garnered four starts. Pages will handle the catching duties for the series opener versus the Brewers.

Barnes went 3-for-4 with one RBI in Sunday's 14-3 loss to the Diamondbacks.

Barnes' three-hit game was a small bright spot in an otherwise awful performance for the Dodgers. The backup catcher has gone 5-for-8 over three contests since he returned from a fractured big toe sustained in mid-August. Through 139 plate appearances, Barnes is slashing .266/.336/.315 with one home run, 11 RBI, 10 runs scored and two stolen bases. He is unlikely to challenge Will Smith for a starting role, but Barnes should be expected in the lineup any time the Dodgers have a day game immediately after a night game.

D'Arnaud will start at catcher and bat fifth in Sunday's game against the Phillies.

Atlanta's timeshare at catcher has tilted in favor of d'Arnaud lately, as he'll pick up his sixth start in nine games Sunday. D'Arnaud holds an 89-point edge in OPS (.774 to .685) over Murphy this season, and that disparity may be enough for the former to see the larger share of playing time behind the dish despite the latter's bigger contract.

Murphy is out of the lineup for Sunday's game against the Phillies.

Murphy has now started just three times in nine games and may be moving into the shorter side of a timeshare at catcher with Travis d'Arnaud. The 29-year-old backstop has been a major disappointment in the second season of a six-year, $73 million contract, having submitted a career-low .685 OPS through 210 plate appearances for Atlanta.

Del Castillo is out of the lineup for Sunday's game against the Dodgers.

The lefty-hitting Del Castillo will hit the bench for the third time in four games, with each of those absences coming against left-handed pitchers. The rookie backstop still appears to be locked into the strong side of a platoon with Jose Herrera while top catcher Gabriel Moreno (adductor) is on the injured list.

Smith is out of the lineup for Sunday's game against the Diamondbacks.

Austin Barnes will spell Smith behind the dish after the latter catcher started in both of the first two games of the series. Despite banging out two hits in Saturday's 8-6 win, Smith still endured a tough August, slashing just .194/.298/.319 with two home runs, 10 RBI and 12 runs on the month.

The Giants recalled Sabol from Triple-A Sacramento on Sunday.

The addition of Sabol gives the Giants a third catcher behind Patrick Bailey and Curt Casali who's also capable of filling in at first base or in the corner outfield in a pinch. Sabol spent the entire 2023 season on the Giants' roster as a Rule 5 selection, but he's logged just 38 plate appearances over 11 games with the big club in 2024.

Bailey is out of the lineup for Sunday's game against the Marlins.

Bailey will get a breather for the day game after he had started at catcher in each of the Giants' three contests while going 1-for-11 with four strikeouts following his return from the injured list Thursday. Curt Casali will check in for Bailey behind the plate.

Sanchez is out of the lineup for Sunday's game against the Giants.

Sanchez had started in each of the Marlins' previous three matchups with right-handed starters, but he'll cede catching duties to Nick Fortes in the series finale while the Giants send right-hander Logan Webb to the hill. Sanchez and Fortes will likely continue to operate in a timeshare down the stretch, and the Marlins' catching picture could become even murkier with Miami using one of its two September call-ups on a third backstop in Jhonny Pereda.
