The Mariners claimed MacIver off waivers from the Blue Jays on Wednesday.

MacIver will report to Triple-A Tacoma, where he will provide the Mariners with some catching depth. The 29-year-old has hit .270/.344/.459 at the Triple-A level in 2026.

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

The Astros will give Diaz a breather for Wednesday's matinee after he caught eight innings of a 4-1 loss Tuesday night. Christian Vazquez will step in behind the plate in place of Diaz.

Orioles manager Craig Albernaz said that Pozo (finger) will be available off the bench for Wednesday's game in Minnesota, Matt Weyrich of The Baltimore Sun reports.

Pozo had to be removed from Tuesday's contest with a finger injury after taking a bat to the catcher's mitt, but X-rays were clean and he won't have any limitations Wednesday. The 29-year-old is 3-for-10 with a home run early on in his tenure in Baltimore.

Heim is not in the lineup for Wednesday's contest against the Rays.

Heim started at catcher in each of the Athletics' last three games, so he will get some rest during Wednesday's matinee. Brian Serven will be behind the dish.

Kolozsvary (undisclosed) went 0-for-4 with two strikeouts Tuesday for Double-A Reading after he was assigned to the affiliate when he was activated from Triple-A Lehigh Valley's 60-day injured list.

Kolozsvary finished the 2025 campaign in the Red Sox organization on Triple-A Worcester's full-season injured list before signing a minor-league deal with Philadelphia in December. The 30-year-old catcher remained shelved to begin the season before starting up a rehab assignment in the Florida State League shortly after the All-Star break. Deemed healthy again after making 12 appearances in the lower levels of the minors, Kolozsvary looks set to fill a depth role at Reading.

Jeffers is not in the lineup for Wednesday's contest versus the Orioles.

Jeffers will grab a seat for Wednesday's matinee after starting behind the dish in the first two games of the series. Victor Caratini will do the catching for the Twins.

Rutschman went 1-for-3 with two walks in Tuesday's 5-3 loss to the Blue Jays.

Rutschman made his debut for the Red Sox and batted third in the order. He was acquired by Boston at the trade deadline but was unable to play before Tuesday due to wrist inflammation. He should serve as the team's primary catcher with Connor Wong slotted as the backup.

Stephenson went 1-for-4 with two RBI in Tuesday's 5-4 extra-inning win over the White Sox.

Cincinnati hitters were befuddled by Chicago starter Sean Burke for seven innings but made their move in the eighth, scoring three runs against the White Sox's bullpen. Stephenson's two-run, bases-loaded single plated the game-tying run and set up the need for an extra frame. The catcher continued a productive stretch since the All-Star break and is slashing .288/.373/.593 with 11 RBI over the last 17 contests.

Campusano went 3-for-4 with a home run, a walk, three RBI and two runs scored in Tuesday's 11-2 win over the Brewers.

Campusano launched San Diego's third homer off Kyle Harrison, taking the left-hander deep for a two-run shot in the fifth inning for his fifth long ball of the season. He added singles in each of his next two at-bats, with one driving in another run to cap his three-RBI performance. Campusano has been swinging a hot bat lately, collecting 14 hits over his last 10 games. He owns an impressive .311 average and .410 OBP on the season, though his .250 expected average suggests some negative regression could be coming.

Cavanaugh went 2-for-4 with one RBI, one stolen base and one run scored in Tuesday's 4-1 win over the Astros.

Cavanaugh logged the first steal of his career when he swiped second in the second inning. The catcher has gone 9-for-34 (.265) at the plate since the All-Star break, and even with Andrew Knizner in the fold, Cavanaugh is likely to get some on-the-job experience in a starting role, at least until Jesus Rodriguez (elbow) is healthy. Cavanaugh is batting .242 with a .609 OPS, no home runs, five RBI, four runs scored and a double over 79 plate appearances in his first taste of the majors this year.
