Narvaez (knee) will serve as Boston's starting catcher again in 2026, Christopher Smith of MassLive.com reports.

According to manager Alex Cora, Narvaez's knee was a problem throughout the entire 2025 season. Narvaez was able to avoid the injured list and remained an excellent defensive backstop, but the injury helps explain his offensive downturn in the second half, when he posted a .187/.233/.387 slash line. Following a left knee meniscectomy in October, Narvaez will slot back in as the No. 1 catcher for the Red Sox ahead of Connor Wong.

Ballesteros has not arrived at spring training yet due to a visa issue, but manager Craig Counsell said he is "expected shortly," Sarah Barber of Sports Illustrated reports.

Ballesteros has yet to receive clearance to travel from his native Venezuela, but Counsell downplayed the issue and said he's not worried at this point about the delay. It's an important spring for the 22-year-old catching prospect, who debuted for the Cubs last season and posted an impressive .868 OPS across 20 games. Ballesteros is the favorite at this point to serve as the Cubs' top DH option in 2026, and he could mix in some behind the plate in relief of Carson Kelly and Miguel Amaya.

Fry will spend the first part of spring training mainly as a catcher, Tim Stebbins of MLB.com reports.

Fry, who was limited to DH and pinch-hitting duties in 2025 following his recovery from Tommy John elbow surgery, will ultimately move around the field for the final weeks of camp. In addition to catching, Fry can play both corner spots in the infield and outfield, giving manager Stephen Vogt flexibility when creating a lineup on any given day. Fry was an All Star in 2024, when he slashed .263/.356/.448 with 14 home runs and 51 RBI in 392 plate appearances over 122 games.

Alvarez said Friday that he lost 8-to-10 pounds this offseason after changing his diet, Laura Albanese of Newsday reports.

Alvarez also added that he worked with director of hitting Jeff Albert in the offseason and plans to keep the batting stance he used down the stretch last season. The young catcher was demoted to Triple-A Syracuse for a while after struggling, and when he returned he went back to his old stance and slashed .276/.360/.561 with eight home runs in his final 40 games. Still just 24, Alvarez is a viable candidate to take a step forward in 2026. He underwent right thumb UCL surgery after the season but reported to spring training at full health.

The Cardinals could explore using Herrera (elbow) in left field or at first base if he's unable to stick at catcher, Derrick Goold of the St. Louis Post-Dispatch reports.

Herrera was limited to designated hitter duties for the final few months of last season due to defensive issues and also a lingering elbow injury that he had surgically corrected in November. The Cardinals gave Herrera a list of things to work on over the offseason in order to improve his game preparation and game management, and they're optimistic his throwing will improve after surgery. If a return to catcher ultimately isn't in the cards, Herrera could be tried out in left field -- where he played four games last season -- or at first base. Herrera is being eased into throwing and hitting in camp but is expected to be fully healthy for Opening Day.

Pozo has lost 33 pounds since the end of last season, he shared on his X account.

The slimmed-down Pozo was non-tendered by the Cardinals in November before quickly re-signing on a split contract. He's part of a crowded mix at catcher for St. Louis, with Ivan Herrera (elbow), Pedro Pages and perhaps Jimmy Crooks ahead of him on the depth chart. Pozo -- who slashed .231/.262/.375 with five home runs in 67 games in 2025 -- is likely to begin the season at Triple-A Memphis.

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.
