Heineman has won a spot on the Blue Jays' Opening Day roster, Gregor Chisholm and Mike Wilner of the Toronto Star report.

The 34-year-old switch hitter will slot in behind Alejandro Kirk on the depth chart. Heineman appeared in 64 regular-season games for Toronto last season, slashing a career-best .289/.361/.416 with three homers, 20 RBI and 25 runs.

The Orioles reassigned Huff to Triple-A Norfolk on Wednesday, Andy Kostka of TheBaltimoreBanner.com reports.

Huff will head to the minors to begin the season after the Orioles weren't compelled to carry him on the Opening Day roster as a third catcher behind Adley Rutschman and Samuel Basallo. As a member of the Giants organization last season, Huff saw action in 20 games at the big-league level and slashed .208/.259/.340 with two home runs and four RBI over 58 plate appearances.

Jackson will remain with the Twins organization after accepting an outright assignment to Triple-A St. Paul, Dan Hayes of The Athletic reports.

With the Twins electing to carry two catchers (Ryan Jeffers and Victor Caratini) on their Opening Day squad, Jackson was designated for assignment during the final roster cutdown of the spring. After none of the other 29 teams were willing to take on Jackson and his $1.35 million contract for 2026, he'll end up sticking around in the organization as catching depth. Jackson should be the top candidate for a promotion if Jeffers or Caratini misses time at any point this year.

The Astros selected Vazquez's contract from Triple-A Sugar Land on Wednesday.

Vazquez will open the season as the Astros' backup catcher behind starter Yainer Diaz. He's hit only .215/.267/.311 the past three seasons in the majors but remains a capable defensive backstop.

The White Sox placed Teel (hamstring) on the 10-day injured list Wednesday.

Teel went down with a Grade 2 right hamstring strain in mid-March while playing for Team Italy during the World Baseball Classic. The young catcher was given a 4-to-6 week timeline for recovery, and his progress so far suggests he has a chance to return closer to the front end of that timetable. While Teel is shelved, Edgar Quero and Reese McGuire will form Chicago's catching tandem.

The White Sox designated Lee for assignment Wednesday.

The White Sox elected to sign Reese McGuire this past weekend, which has pushed Lee off the roster. He's just a .193/.234/.321 hitter over parts of four big-league seasons, but there's a good chance Lee will find work soon from a club seeking catching depth.

Boston placed Seigler on the 10-day injured list Wednesday due to left knee patellar tendinopathy.

Acquired from the Brewers on Feb. 9, Seigler didn't end up making any appearances in spring training while recovering from a knee injury that first surfaced while he played in the Dominican Winter League during the offseason. The Red Sox haven't indicated where Seigler stands in his recovery, so the 26-year-old appears destined to miss more than the minimum 10 days. Seigler has two minor-league options remaining and could be sent out to Triple-A Worcester to play regularly once he's activated from the IL.

The Twins designated Jackson for assignment Wednesday, Aaron Gleeman of The Athletic reports.

Jackson was acquired via trade from the Orioles in November and signed to a one-year, $1.35 million contract. However, the Twins later signed Victor Caratini to serve as the backup catcher, making Jackson expendable. If he's not traded, Jackson will likely pass through waivers due to his contract and could accept an assignment to Triple-A St. Paul.

Diaz went 1-for-2 with a pair of RBI in Tuesday's exhibition matchup against Triple-A Sugar Land.

Diaz is starting to warm up just in time after struggling for much of spring training -- the 27-year-old backstop finished Grapefruit League play with a .143/.226/.214 slash line, no homers and just two extra-base hits across 11 games. Still, Diaz should offer some upside at the catcher position after batting .256 with 20 homers, 70 RBI and a .701 OPS across 143 regular-season games in 2025.

Jeffers went 3-for-3 with two RBI in the Grapefruit League finale win against Boston on Tuesday. He hit .239 (11-for-46) with a home run this spring. He's set to get the bulk of starts behind the plate plus occasional starts at DH, MLB.com reports.

Jeffers split playing time with Christian Vazquez last season as the Twins emphasized keeping their catchers fresh. However, Jeffers is expected to get the majority of starts this season under new manager Derek Shelton with Victor Caratini serving as his backup.
