Plawecki announced his retirement on his personal Instagram page Saturday.

Plawecki served as a backup catcher in the majors from 2015-2022 and was in a few minor-league systems for the last two campaigns. He ended his playing career with the Padres at Triple-A El Paso and also announced that he would remain with the team as a minor-league coach.

Knizner signed a minor-league contract with the Nationals on Friday and received an invitation to spring training, Andrew Golden of The Washington Post reports.

Knizner spent the majority of last season with the Rangers, slashing just .167/.183/.211 over 93 plate appearances before being DFA'd in August. He posted a .743 OPS with the Diamondbacks' Triple-A affiliate to close the season and will likely report to Triple-A Rochester to begin the 2025 campaign.

The Mariners outrighted Raposo to Triple-A Tacoma.

He's no longer on the 40-man roster but will remain in the organization as catching depth. Raposo, 26, has a career .241/.321/.387 slash line in the minors and has yet to see any action at the big-league level.

The Reds re-signed Wynns (shoulder) to a minor-league contract Jan. 13.

Wynns, 34, spent most of the 2024 season at Triple-A Louisville and suffered a season-ending teres major tear in his right shoulder in late July during one of his seven games with the Reds. It's not clear whether he'll be healthy for the start of spring training, but either way he's slated to begin 2025 at Louisville.

The Red Sox acquired Sabol from the Giants on Wednesday in exchange for international bonus pool space, Hunter Noll of Beyond the Monster reports.

Sabol had been designated for assignment but will now join a new 40-man roster. The 27-year-old has put up a .705 OPS over 121 games at the big-league level and is capable of playing the outfield in addition to catching. Sabol is likely to begin the 2025 campaign at Triple-A Worcester.

The Mariners acquired Hunt from the Orioles on Wednesday in exchange for cash considerations.

The 26-year-old had been designated for assignment. It's a homecoming of sorts of Hunt, who began last season in the Mariners organization before being traded to the Orioles. He's likely to begin the 2025 season at Triple-A Tacoma, where he'll represent catching depth.

The Mariners designated Raposo for assignment Tuesday, Shannon Drayer of SeattleSports.com reports.

The move frees up a spot on the 40-man roster for Miles Mastrobuoni, who was acquired via trade. Raposo was a waiver claim by the Mariners in December and will now go through the waivers process again.

The Orioles designated Hunt for assignment Monday, Andy Kostka of TheBaltimoreBanner.com reports.

The Orioles made the signing of Andrew Kittredge official Monday and needed to free up a spot on their 40-man roster. Hunt, 26, slashed only .179/.219/.278 over 42 games during his time with Triple-A Norfolk last season.

The Giants designated Sabol for assignment Saturday, Alex Pavlovic of NBC Sports Bay Area reports.

The move makes room on the Giants' 40-man roster for Justin Verlander, whose one-year, $15 million contract was officially signed Saturday. Sabol spent most of the 2024 regular season with Triple-A Sacramento, where he slashed .246/.340/.388 with 11 stolen bases, 11 home runs and 54 RBI across 403 plate appearances. He appeared in 11 regular-season games with the Giants, going 10-for-32 with five walks, two doubles and one RBI.

The Diamondbacks claimed Pinto off waivers from the Orioles on Friday, Alex Weiner of ArizonaSports.com reports.

Pinto has slashed .231/.263/.404 with 10 homers over 82 games at the big-league level but spent most of 2024 at Triple-A Durham in the Rays organization. He is out of minor-league options, so the Diamondbacks will need to carry him on the Opening Day roster or attempt to pass him through waivers.
