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

Diaz will head to the bench after starting in the first two games of the series in Boston and going 1-for-8 with two walks, two runs and an RBI. He'll have a more crowded path to playing time moving forward after the Astros activated Michael Brantley from the 60-day injured list Tuesday, but manager Dusty Baker will likely look to find ways to keep Diaz's bat in the lineup so long as the rookie remains productive. Diaz has compiled a .917 OPS over 36 games since the All-Star break.

Langeliers is absent from the lineup for Wednesday's game versus the Mariners, Martin Gallegos of MLB.com reports.

It's a day game after a night game, so the Athletics' starting catcher will get a breather. Carlos Perez will be behind the plate Wednesday.

Higashioka went 1-for-4 with a solo home run Tuesday in a 4-2 win against the Tigers.

HIgashioka accounted for New York's second run of the contest with his fifth-inning solo homer. The long ball was the second in three games for the backstop and his third over his past seven contests, though all have been solo shots. With Ben Rortvedt slashing a measly .122/.246/.265 on the campaign, Higashioka has settled into the primary catcher role for the Yankees, starting each of the team's past three games.

Jeffers will start at catcher and bat seventh in Wednesday's game against the Guardians.

Despite going 0-for-9 with six strikeouts in his last two starts, Jeffers will be behind the dish for the fourth time in six contests as the Twins close out their series with the Guardians. Jeffers owns a .965 OPS since the All-Star break and looks to be the Twins' preferred option at catcher over Christian Vazquez for the moment.

Vazquez is out of the lineup for Wednesday's game against the Guardians.

The Twins' catching timeshare has tilted in favor of Ryan Jeffers of late, leaving less playing time available for Vazquez. The 33-year-old will be on the bench Wednesday for the fourth time in the last six games.

Jansen is out of the lineup for Wednesday's game against the Nationals.

Toronto and Washington are wrapping up their series with a day game after a night game, so Jansen will rest after catching all nine innings of Tuesday's 5-4 win. Alejandro Kirk will spell Jansen behind the dish Wednesday.

Naylor is out of the lineup for Wednesday's game against the Twins.

Naylor will take a seat for the afternoon game after he was behind the plate for 17 innings between the past two days. Eric Haase will step in as the Guardians' starting catcher in the series finale.

Garver went 1-for-2 with two walks, a solo home run and a second run scored in Tuesday's 2-1 win over the Mets.

All the scoring came late, as Garver broke open a scoreless tie by taking Drew Smith deep in the seventh inning before scoring what proved to be the winning run on an Ezequiel Duran single in the top of the ninth. Garver has gone yard four times in his last six games, all solo shots, and he's slashed a stellar .317/.404/.659 through 23 games in August with eight of his 13 homers on the year and 16 of his 36 RBI. Even with Jonah Heim healthy, the Rangers will continue finding room for Garver in the starting nine as long as he's locked in, either at catcher or DH.

Rutschman is out of the lineup for Wednesday's game against the White Sox.

Rutschman often serves as a designated hitter on days that he doesn't catch, but he'll get a proper day off Wednesday in what marks just his third absence from the lineup since the All-Star break. With James McCann stepping in behind the dish, Ryan Mountcastle will get a look as the Orioles' designated hitter. The day off comes while Rutschman has been running hot at the plate, as he's recorded at least one hit in eight of his last nine starts while slashing .333/.366/.359.

Lee is out of the lineup for Wednesday's game against the Orioles.

Lee will sit for Wednesday's matinee contest after he started behind the dish in both of the first two games of the series, going 0-for-6 with a walk. Yasmani Grandal will form a battery with starting pitcher Dylan Cease on Wednesday.
