Del Castillo is dealing with a left calf issue, Alex Weiner of Arizona Sports reports.

He's been working off to the side since reporting to camp earlier this week. Arizona manager Torey Lovullo said Del Castillo will be brought along slowly this spring, but it's unclear how long that period might last. The 26-year-old's bat is seen as an asset and more developed than his defense, and while there are no plans to move Del Castillo out from behind the plate, he's third on the depth chart and likely to see more time at DH than catcher in 2026.

Cardinals president of baseball operations Chaim Bloom said Thursday that Herrera (elbow) remains limited with his throwing and hitting, Derrick Goold of the St. Louis Post-Dispatch reports.

Herrera underwent surgery in November to remove bone spurs from his right elbow, so he's being eased into things in spring training. The elbow rehab will keep Herrera from participating in the World Baseball Classic for his native Panama due to insurance issues, but it is not expected to affect his Opening Day availability. Herrera is attempting to return to catcher in 2026 after the elbow issue limited him to designated hitter duty for the final few months of the 2025 season.

Contreras (finger) signed a one-year contract with the Brewers on Thursday to avoid arbitration.

Contreras' new deal also includes a club option for the 2027 season. The 28-year-old's production dipped a bit in 2025, as he slashed .260/.355/.399 with 17 homers, 76 RBI and 89 runs scored over 150 regular-season games while playing through a fractured finger for most of the year. He underwent surgery in the offseason to address the issue and is expected to be fully recovered by Opening Day.

Ruiz has been cleared of any concussion symptoms to begin spring training, Jessica Camerato of MLB.com reports.

The 27-year-old was limited to only 68 games last season after being struck in the head by a foul ball in late June, but Ruiz's offensive numbers were lagging even prior to the concussion issues that cost him the final three months of 2025. He'll compete in camp with Harry Ford, acquired from the Mariners in the Jose Ferrer trade this offseason, for the top job behind the plate with the Nationals.

Ramirez has committed himself this offseason to improving his defense behind the plate, Jordan McPherson of the Miami Herald reports. "I was learning something new every game," Ramirez said Wednesday about his rookie campaign in the majors. "That's what I was experiencing last season. I'm coming with that experience this year. It feels really good because you know exactly where to go and what to do."

The 24-year-old has already impressed with the offensive side of his game -- he was the first rookie catcher in MLB history to record 20 homers and 15 steals in a season -- but Ramirez's defense needs a lot of work. He spent the offseason in the Dominican Republic working on his mobility, to improve his range and ability to block balls in the dirt, but that's not the only hole in his skill set. Ramirez's minus-14 defensive runs saves in 2025 included a rough 8.8 percent caught-stealing rate, as base stealers were successful on 82 of 91 attempts against him. His bat will be a fixture in the Marlins' lineup in 2026, but if Ramirez's defense continues to be an issue, he could be moved to first base or DH considering top catching prospect Joe Mack is knocking on the door at Triple-A.

The Brewers signed Sanchez (knee) to a one-year, $1.75 million contract Wednesday, Jon Heyman of the New York Post reports.

Sanchez spent the 2024 season with the Brewers, slashing .220/.307/.392 with 11 home runs over 89 regular-season contests. He was limited to only 29 contests last season with Baltimore due to a knee injury, and it's unclear whether he will have any limitations in camp with Milwaukee. Sanchez should open 2026 as the backup catcher behind William Contreras (finger). He could also see the occasional start at designated hitter versus left-handed pitching.

The Dodgers designated Rortvedt for assignment Wednesday.

Rortvedt will be removed from the Dodgers' 40-man roster for the second time this offseason after previously being designated for assignment in November. The team will hope to keep him around as catching depth at Triple-A if he clears waivers this time around.

Rodriguez (elbow) took live batting practice against Mitch Keller on Wednesday and appears to be fully healthy for spring training, Colin Beazley of the Pittsburgh Post-Gazette reports.

Rodriguez closed 2025 on the shelf after undergoing ulnar nerve transposition surgery on his right elbow Aug. 12, but he was able to resume a throwing program over the winter. Since he had also been limited to only a handful of rehab games during the 2024 season after undergoing Tommy John surgery on the same elbow, Rodriguez's long-term future as a catcher is in some doubt, but the Pirates don't appear ready to move him off the position just yet. Henry Davis and Joey Bart remain the frontrunners to open 2026 as the Pirates' top two catchers, but with a strong spring at the plate, Rodriguez could still push his way onto the Opening Day roster as a No. 3 backstop and a backup option at first base.

Amaya (ankle) said his body feels "100 percent, good to go" heading into the World Baseball Classic and the regular season, Jordan Bastian of MLB.com reports.

Amaya had an injury-riddled 2025 campaign, with a sprained ankle in mid-August ultimately shutting him down. Before that, the catcher missed about two and a half months due to an oblique strain. Overall, Amaya managed to appear in only 28 games for the Cubs. He said he feels recovered now, and the backstop is prepared to play for Panama in the upcoming WBC as a ramp-up to the regular season. The 26-year-old did muster a career-best .814 OPS last year despite the injuries, and if he can stay healthy, he figures to split time behind the plate with Carson Kelly in 2026. While the arrangement could limit Amaya's ceiling, he still has the offensive talent to take a step forward from a fantasy perspective, particularly if Kelly slumps or gets hurt.

Stephenson will earn $6.8 million in 2026 after winning his arbitration hearing against the Reds, Gordon Wittenmyer of The Cincinnati Enquirer reports.

The two sides went to a hearing despite just a $250,000 difference in their submitted arbitration figures, and the three-person panel ultimately picked Stephenson's filing. Stephenson put up a .737 OPS with 13 home runs over 88 regular-season contests for the Reds this past season and will be their top catcher again in 2026. He is slated to reach free agency next offseason.
