The Mets selected Senger's contract from Triple-A Syracuse on Thursday.

Senger made the Opening Day roster as a backup catcher and made his MLB debut in Thursday's 3-1 loss to the Astros, striking out in his lone plate appearance. The 28-year-old is likely to see limited playing time at catcher behind Luis Torrens and should head to the minors once Francisco Alvarez (hand) is ready to return from the injured list.

Amaya went 2-for-5 with two doubles and five RBI during Thursday's 10-6 win against the Diamondbacks.

The 26-year-old started behind the plate and batted ninth in the Cubs' domestic opener, and he powered the offense with a three-run double in the fifth inning and a two-run double in the ninth. Amaya has been a bright spot in his first two games of the season, going 3-for-8 with three doubles and six RBI, which could help him move up from the bottom of the lineup.

Ruiz went 2-for-4 with a solo home run in Thursday's 7-3 extra-inning loss to the Phillies.

Ruiz got the Nationals into the scoring column with a fifth-inning solo blast off Phillies ace Zack Wheeler. The switch-hitting backstop excelled this spring while batting .289 with three homers, 11 RBI, and two stolen bases over 45 Grapefruit League at-bats, and Ruiz should see plenty of action in 2025 as Washington's primary catcher.

Rodriguez went 0-for-3 with one walk and three strikeouts during Thursday's 5-4 loss to the Marlins.

Rodriguez got the start at first base Opening Day due to Spencer Horwitz (wrist) starting the season on the 10-day injured list. Rodriguez opened things up with a six-pitch walk in the third inning, but he proceeded to strike out in each of his next three plate appearances, the first two of which came on three pitches. The 24-year-old is serving as the backup catcher to Joey Bart but should also split time at first base with Jared Triolo until Horwitz is healthy.

Romo is not on the Triple-A Albuquerque roster to begin the season as he is being evaluated for a finger injury, Patrick Lyons of JustBaseball.com reports.

Romo entered spring training projected to make the Opening Day roster, though Hunter Goodman performed extremely well to claim the backup catcher job. The severity of the issue is unclear, but Romo should make an appearance in the majors at some point in 2025, assuming he isn't sidelined for a lengthy period.

Rodriguez will start at first base and bat seventh in Thursday's opener against the Marlins.

Rodriguez is the backup catcher behind Joey Bart, but he will also see ample time at first base while Spencer Horwitz (wrist) is on the shelf. Jared Triolo -- who likely represents Rodriguez's primary competitor for playing time at first base -- will begin Thursday's game on the bench.

The Mets placed Alvarez (hand) on the 10-day injured list Thursday.

Alvarez had the stitches removed from his surgically repaired left hand earlier this week and will begin strengthening exercises. He could be ready to make his season debut by the end of April if all goes well in his rehab.

Maldonado has been informed that he will make San Diego's Opening Day roster, Kevin Acee of The San Diego Union-Tribune reports.

Maldonado's shortcomings as a hitter are well-documented -- he hasn't notched a regular-season batting average above .191 since 2020 and slashed a meager .167/.310/.208 during spring training this year. However, the veteran's defense and ability to work with pitchers are well respected, which appears to be enough for him to break camp with the big club as the Padres' No. 2 catcher behind Elias Diaz. Former vaunted prospect Luis Campusano was optioned to Triple-A El Paso on Monday, but Maldonado's roster spot could be challenged at any point in the season if Campusano shows growth with the bat in the minors.

The Giants reassigned Stassi to Triple-A Sacramento on Wednesday.

Even with the Giants placing Tom Murphy (back) on the 60-day injured list to begin the season, Stassi was unable to secure a spot on the Opening Day roster as a backup catcher. The Giants will instead go with Sam Huff as the No. 2 option behind top backstop Patrick Bailey, while Stassi heads to Triple-A. Stassi hasn't seen big-league action since 2022 and was limited to just five games in the minors in 2024 before undergoing a season-ending left hip surfacing procedure last June.

The Giants placed Murphy (back) on the 60-day injured list Wednesday.

Murphy was diagnosed with a mid-back disc herniation in February and was expected to miss Opening Day for much of spring training, and his placement on the 60-day IL will ensure that he remains out until at least late May. While Murphy works his way back, Sam Huff will fill in as the backup catcher behind Patrick Bailey, and Christian Koss will claim the open spot on the 40-man roster.
