The Cubs signed McGuire to a minor-league contract Wednesday, Aram Leighton of Just Baseball reports.

McGuire, who will turn 30 in March, sports a career .252/.300/.364 batting line over parts of seven major-league seasons. The veteran backstop will likely begin the 2025 campaign at Triple-A Iowa as catching depth.

Atlanta signed Casali to a minor-league contract Jan. 17 that includes an invitation to spring training, Aram Leighton of Just Baseball reports.

Atlanta has an opening at backup catcher behind Sean Murphy that Casali could potentially fill. The 36-year-old appeared in 41 games for the Giants in 2024, putting up a .543 OPS with one home run.

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 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 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.

Stephenson agreed to a one-year, $4.925 million contract with the Reds on Thursday to avoid arbitration, Ari Alexander of KPRC 2 Houston reports.

Stephenson receives a $2.4 million raise in his second year of arbitration eligibility after slashing .258/.338/.444 and setting career highs with 19 homers, 69 runs scored and 66 RBI in 2024. The Reds' offseason acquisition of Jose Trevino shouldn't cut too much into Stephenson's playing time, and the 28-year-old still projects as one of the better offensive backstops in the majors.

The Marlins and Fortes avoided arbitration by agreeing to a one-year contract Thursday, Christina De Nicola of MLB.com reports.

Fortes, 28, has managed just a .222/.275/.344 batting line over parts of four major-league seasons. He sits atop the Marlins' depth chart at catcher but is not an appealing fantasy option.

The Reds and Trevino avoided arbitration by agreeing to a one-year, $3.425 million contract Thursday, Jon Heyman of the New York Post reports.

Picked up in a trade with the Yankees last month, Trevino was arbitration-eligible for the third and final time. The 32-year-old will be the Reds' No. 2 catcher in 2025 behind Tyler Stephenson.

Bart and the Pirates avoided arbitration Thursday by agreeing to a one-year, $1.75 million deal, Andrew Destin of the Pittsburgh Post-Gazette reports.

The No. 2 overall pick in the 2018 First-Year Player Draft was unable to establish himself as the Giants' long-term answer at catcher over parts of four seasons in the big leagues, but the 28-year-old benefited from a change of scenery after he was shipped to Pittsburgh in April. He ended the 2024 campaign as the Pirates' top catcher, having slashed .265/.337/.462 with 13 home runs, 45 RBI and 38 runs across 282 plate appearances. The Pirates have 2021 No. 1 overall pick Henry Davis and 24-year-old Endy Rodriguez on hand as intriguing young options at catcher, but based on his performance last season, Bart will enter spring training as the favorite to open the 2025 campaign as the Bucs' top backstop.
