Casas (knee) has been at Boston's training facility in Fort Myers since the end of the regular season, Lauren Campbell of MassLive.com reports.

It's unclear the type of activity in which Casas has been engaged, but Red Sox manager Alex Cora continues to have faith in the young first baseman, who was limited to 29 games last season. "That's great for a young guy to know what he needs to do to compete," the manager said. "He's done that. Hopefully we can get him heathy." The shortened 2025 season was the second consecutive one for Casas, who was limited to 63 games in 2024 due to a fractured rib. Casas is not a lock to return as the starting first baseman, and the Red Sox are rumored to have interest in free agent first baseman Pete Alonso.

Cardinals president of baseball operations Chaim Bloom said Tuesday that Thompson (lat) should be ready for the start of spring training, Derrick Goold of the St. Louis Post-Dispatch reports.

Thompson missed the entirety of the 2025 season due to a left lat strain, encountering multiple setbacks along the way. He was removed from the Cardinals' 40-man roster last month, but the southpaw remains in the organization and will compete for a roster spot in spring training.

Atlanta manager Walt Weiss said Tuesday that Lopez (shoulder) will be stretched out as a starting pitcher during spring training, Mark Bowman of MLB.com reports.

Weiss noted that Lopez could eventually become a bullpen option if that's the route the team ultimately decides to take, but for the time being Lopez will prepare to be in Atlanta's 2026 rotation. The right-hander missed nearly the entire 2025 season following arthroscopic right shoulder surgery in April, but he was throwing off a mound by September and should be ready for the start of spring training.

The Angels acquired Grissom from the Red Sox on Tuesday in exchange for Isaiah Jackson, Chris Cotillo of MassLive.com reports.

Grissom had a forgettable tenure in Boston after being sent there from Atlanta in the Chris Sale trade. He slashed only .190/.246/.219 with zero home runs over 31 games during the 2024 season before spending all of 2025 at Triple-A Worcester, where he slashed .270/.342/.441 with 13 home runs. Grissom -- who will turn just 25 in January -- is out of minor-league options and will get a fresh start with the Angels. Most of Grissom's experience has come in the middle infield, but he's also handled third base, first base and left field.

Blue Jays manager John Schneider said Tuesday that Santander's left shoulder and back "finally feel normal" again, Mitch Bannon of The Athletic reports.

Santander was limited to only 54 games in 2025 due to a shoulder subluxation and also a nagging lower-back issue. He slashed just .175/.271/.294 in those contests and saw his strikeout rate spike to 27.6 percent. It appears Santander is healthy now, though, and Schneider believes the 31-year-old "is going to be huge for us." Santander split his time between the outfield and designated hitter in 2025 and could do the same in 2026.

The Angels re-signed Rivero to a minor-league contract Tuesday, Taylor Blake Ward of The Sporting Tribune reports.

Rivero was non-tendered by the Halos last month but is back with the club on a minor-league pact. He's hit .172/.226/.212 over 45 games at the big-league level and will give the Angels some experienced catching depth at Triple-A Salt Lake.

Dodgers general manager Brandon Gomes has said that Graterol (shoulder) will be "full-go" for spring training, Fabian Ardaya of The Athletic reports.

Graterol missed the entire 2025 season following November 2024 labrum surgery on his right shoulder. He experienced a setback with the shoulder during the second half, but it appears the hard-throwing reliever is back on track now. Graterol has hardly pitched the last two seasons because of injury, but he held a 1.20 ERA over 68 appearances in 2023, his last full season.

The Dodgers signed Diaz to a three-year, $69 million contract Tuesday, Jeff Passan of ESPN.com reports.

For the second straight offseason the Dodgers have inked the top closer on the free-agent market. The $23 million average annual value sets a new record for a reliever. Diaz will turn 32 in March but is coming off one of his best seasons, having collected a 1.63 ERA, 0.87 WHIP and 98:21 K:BB over 66.1 innings while notching 28 saves. He will take over as closer for the two-time defending World Series champs.

The Phillies re-signed Schwarber to a five-year, $150 million contract Tuesday, Jeff Passan of ESPN.com reports.

Schwarber had a robust market, but it always seemed inevitable that he would return to Philadelphia. A five-year deal for a designated hitter heading into his age-33 season is risky on paper, but Schwarber is coming off his best season, having posted a .928 OPS with 56 home runs and 132 RBI during the regular season. He will be the Phillies' full-time DH again in 2026.

The Royals plan to keep India at second base in 2026 rather than playing him at multiple positions, Ken Rosenthal of The Athletic reports.

India played third base and left field in addition to second base in 2025, and the Royals believe all the moving around could have affected the 29-year-old's offense, as he slashed just .233/.323/.346 in his first year in Kansas City. It was a bit of a surprise that Royals brought India back for $8 million rather than non-tendering him, but they're confident he can bounce back in his walk year.
