Dingler (elbow) is working through a return-to-play throwing progression this week and is expected to be ready to return in early March, MLB.com reports.

Dingler underwent arthroscopic surgery on his right elbow at the end of January and has been working his way back in recent weeks. He has been taking part in all other baseball activities, and now his throwing seems to be nearly back to normal as well. With more than a month to go until Opening Day, Dingler doesn't seem to be in any danger of missing regular-season contests, and he should be Detroit's clear top catcher after a strong 2025 campaign.

Diaz (foot) will be the designated hitter Wednesday and will start at catcher in Friday's Grapefruit League game, Matt Kawahara of the Houston Chronicle reports.

Diaz was delayed due to a foot sprain suffered in the Dominican Winter League, but he isn't too far behind, as he's scheduled to catch in a game before the end of February. Cesar Salazar is Diaz's only backup, so there should be ample playing time available for the latter once he puts the foot sprain behind him.

Red Sox manager Alex Cora said Tuesday that Seigler is nursing a knee injury that he first suffered in the Dominican Winter League, Mac Cerullo of the Boston Herald reports.

Seigler felt fine at the beginning of camp, but now the knee is barking again. It's not clear whether he will be sent for testing or will simply rest for a bit. Acquired from the Brewers in a trade this offseason, Seigler is competing for a reserve role with the Red Sox.

Jansen went 1-for-2 with a two-run home run and a walk in Monday's Cactus League game against the Angels.

Jansen pieced together a few strong at-bats during Monday's exhibition. He struck for a two-run home run in the top of the first inning to get his squad on the board, and he later drew a six-pitch walk in the top of the fourth. Jansen hit second in the batting order Monday after being slotted in as the No. 3 hitter in his spring debut Saturday, though this is likely a strategy to get him as many at-bats as possible early in spring training games.

Jensen started at catcher and went 1-for-3 in Sunday's Cactus League win over the Brewers.

Jensen was out of the lineup for the Royals' first two games before making his spring debut Sunday, grounding out in his first two at-bats before pulling a single into right field in the sixth inning before being lifted. One of the most highly touted catching prospects in baseball, the 22-year-old mashed during his brief stint with the Royals in 2025, slashing .300/.391/.550 with nine extra-base hits and 13 RBI across 20 games in September. The presence of franchise icon Salvador Perez is worth noting, but Jensen should still see regular action in the Kansas City lineup in 2026, whether behind the plate or at designated hitter.

The Royals signed Diaz to a minor-league contract Friday that includes an invitation to spring training.

Diaz is expected to report to Royals camp next week. The 35-year-old appeared in 106 regular-season contests for the Padres last season, slashing .204/.270/.337 with nine long balls. Unless the Royals carry three catchers on their Opening Day roster, Diaz is likely ticketed for Triple-A Omaha.

The Mariners signed Garver to a minor-league contract Wednesday, Jeff Passan of ESPN.com reports.

Garver spent the last two seasons with the Mariners serving as the team's backup catcher to Cal Raleigh. Garver will get a chance to reprise that role for the 2026 campaign, and he'll face competition from Jhonny Pereda and Andrew Knizner in spring training. Garver appeared in 87 regular-season games for Seattle in 2025 and slashed .209/.297/.343 with three steals, nine home runs and 30 RBI across 290 plate appearances.

Wong (hand) took part in live batting practice Monday, Ian Browne of MLB.com reports.

Wong reported to camp last week and appears to be fully healthy after he underwent a carpal boss excision procedure on his right hand back on Oct. 9. The hand issue perhaps played a factor in Wong's dramatic drop in production in 2025, when his OPS fell to .500 over his 188 plate appearances after he had posted a .758 OPS the season prior. Carlos Narvaez ended up overtaking Wong on the depth chart, and manager Alex Cora relayed Saturday that Narvaez "earned the right" to be the team's starter heading into 2026, per Gabrielle Starr of the Boston Herald. Cora added that Wong's solid defense behind the plate should allow him to play more frequently than the typical backup catcher, and the 29-year-old could also be an option to make starts first base when Willson Contreras needs a day off.

Perez (thumb) took live batting practice during Monday's full-squad workout, Anne Rogers of MLB.com reports.

Perez had previously injured his thumb during the offseason while playing in the Venezuelan Winter League, but he looks to have made a full recovery prior to reporting to camp last week. The 35-year-old Perez heads into the upcoming campaign with considerable tread on his tires after logging at least 140 starts in four of the past five seasons. However, the Royals made more of an effort to keep him fresh last season by limiting him to 89 starts at catcher, with his other 66 coming at either designated hitter or first base. With young catcher Carter Jensen expected get a full-time look in the majors in 2026, the Royals should be able to continue managing Perez's workload behind the dish while still keeping his bat in the lineup on a near-everyday basis.

The Tigers announced Sunday that Dingler (elbow) is working his way through a throwing progression, but he's taking part in all other baseball activities, Evan Petzold of the Detroit Free Press reports.

After a Gold Glove-winning 2025 campaign, Dingler underwent arthroscopic surgery on his right elbow Jan. 28 and is still working his way back to full strength. While the backstop will need to prove he can throw with his usual velocity and distance in order to avoid a stint on the injured list to open the season, Dingler should be able to pick up at-bats at designated hitter during Grapefruit League games until he's cleared for defensive duties.
