Thaiss (undisclosed) was activated from the 7-day injured list for Triple-A Salt Lake on Saturday, Sam Blum of The Athletic reports.

Thaiss has been out for two weeks with an unspecified issue, but he's good to go again now. He hit a modest .226/.300/.452 in 17 games prior to the injury and probably has to show more than that if he's to push for a return to the majors.

Diaz won't start the second half of Saturday's doubleheader against the Mets.

Diaz went hitless in four at-bats in the first game of the day. Brian Serven takes over behind the plate in the nightcap.

Contreras was removed from Saturday's game against the Diamondbacks due to right hamstring tightness, Patrick Mooney of The Athletic reports.

Contreras started Saturday's game as the designated hitter and went 1-for-2 with a stolen base. While he singled and swiped a bag in the bottom of the third inning, he apparently tweaked something since Rafael Ortega took over as a pinch runner. The severity of the 30-year-old's injury isn't yet clear, but Yan Gomes should see increased work behind the dish if Contreras misses additional time.

Narvaez will sit against lefty Patrick Corbin and the Nationals on Saturday.

Narvaez has only made a single start against a southpaw this season, so it's no surprise to see him on the bench here. Victor Caratini will get the start behind the plate.

Stallings will sit Saturday against Atlanta, Jordan McPherson of the Miami Herald reports.

Stallings has handled a heavy workload behind the plate this season -- he's currently tied for fourth with 28 starts at the catcher position. He'll get a rest Saturday, with Payton Henry catching for Elieser Hernandez.

Rutschman is starting at catcher and batting sixth Saturday against the Rays.

Rutschman's contract was selected by the Orioles on Saturday, and he'll bat sixth during his major-league debut. The 24-year-old appeared in 19 minor-league games to begin the year and slashed .309/.427/.515 with three homers, five doubles, 12 runs and nine RBI. The highly touted prospect is in line to serve as the Orioles' everyday catcher now that he's on the big-league roster.

Maldonado will sit Saturday against the Rangers.

Maldonado has handled a heavy workload behind the plate as usual this season despite the fact that he hasn't done much with his bat. He's hit .121/.206/.242, but his 29 games started as a catcher rank third in the league. Jason Castro will start in Maldonado's place Saturday.

D'Arnaud isn't starting Saturday against the Marlins.

D'Arnaud will get a breather after he went 3-for-8 with a homer, a double and two RBI over the last two games. William Contreras will take over behind the dish and bat eighth.

Bart will sit Saturday against San Diego, Jeff Sanders of The San Diego Union-Tribune reports.

Bart finds himself on the bench for the fourth time in the last five games. He's hit just .103/.278/.207 while striking out 44.4 percent of the time in the month of May. Michael Papierski will make his major-league debut behind the plate.

Casali was placed on the 7-day concussion injured list Saturday, Alex Pavlovic of NBC Sports Bay Area reports.

Casali was hit by a foul tip on his mask during Friday's loss to the Padres, and he'll be unavailable for at least a week after being diagnosed with a concussion. However, the Giants are hopeful that the 33-year-old will be able to return after missing the minimum of seven days. Michael Papierski's contract was selected by the Giants, and he'll start behind the dish Saturday against San Diego.
