The Tigers designated Leonard for assignment Tuesday.

Leonard slashed .263/.326/.455 with 10 home runs across 282 plate appearances for Triple-A Toledo in 2024. The Tigers are designating him for assignment to create space for one of the three pitchers being added to the 40-man roster Tuesday.

The Cubs selected Cowles to their 40-man roster Tuesday, Andy Martinez of Marquee Sports Network reports.

Cowles was acquired from the Yankees at the trade deadline as part of the Mark Leiter deal, though a wrist injury limited Cowles to playing just four games with Double-A Tennessee at the very end of the year. Prior to his injury, the 24-year-old infielder had slashed .292/.372/.471 with 52 RBI across 379 plate appearances. He'll likely be bumped up to Triple-A Iowa for the start of 2025.

The White Sox selected Montgomery's contract from Triple-A Charlotte on Tuesday, James Fegan of SoxMachine.com reports.

Montgomery slashed only .214/.329/.381 with 18 home runs and a 28.6 percent strikeout rate this season at Charlotte, although at 22 (he'll turn 23 in February), he was quite young for that level. He could use some more seasoning, but with a fast start next season, Montgomery could push to see time at shortstop with the big club.

Adames rejected the Brewers' one-year, $21.05 million qualifying offer Tuesday, Adam McCalvy of MLB.com reports.

It was an easy decision for Adames, who is set to receive a large, multi-year contract in free agency. Assuming the 29-year-old leaves Milwaukee -- which is fully expected -- the Brewers will receive a draft pick as compensation.

Barrero signed a minor-league contract with the Cardinals on Saturday and received an invitation to spring training, Francys Romero of BeisbolFR.com reports.

Barrero owns just a .497 OPS across 447 plate appearances in his major-league career, and his offensive woes followed him to Triple-A last season, where he slashed .188/.277/.345 over 49 games. His chances of contributing for the Cardinals will remain low as long as he continues to struggle at the plate, though the 26-year-old may still see a healthy amount of playing time with Triple-A Memphis.

The Angels signed Newman to a one-year, $2.5 million contract with a $2.5 million club option for 2026 on Thursday, Jon Heyman of the New York Post reports.

The veteran infielder could be the current favorite to open next season at shortstop for the Angels if Zach Neto (shoulder) isn't ready. Newman slashed .278/.311/.375 with three homers and eight steals in 111 games for the Diamondbacks in 2024 and graded out as a plus-four in Outs Above Average at shortstop.

The Angels are nearing a contract agreement with Newman, Will Sammon and Sam Blum of The Athletic report.

It's not clear whether it's a major-league or minor-league contract. Newman, 31, spent the 2024 season with the Diamondbacks, slashing .278/.311/.375 with three homers and eight steals in 111 games. With Zach Neto (shoulder) looking iffy for Opening Day, Newman would provide the Angels with some protection at shortstop.

Franco (personal) is facing charges of illegal use and possession of a firearm related to his arrest in an altercation in the Dominican Republic on Sunday, Juan Recio of ESPN.com reports.

Franco is expected to be granted provisional release Tuesday, although terms of his bail have not yet been defined. The 23-year-old is on MLB administrative leave and is due to stand trial on Dec. 12 in the Dominican Republic involving charges of sexual abuse, sexual exploitation against a minor and human trafficking. A concurrent investigation of Franco is being performed by MLB under its domestic violence, sexual assault and child abuse policy.

Atlanta acquired Allen from the Athletics on Monday in exchange for Jared Johnson.

Allen, 26, has managed just a .209/.254/.283 batting line over parts of three seasons at the major-league level. He does have a reputation as a solid glove at shortstop, although he came in at negative-2 Outs Above Average during his 41 games with the Athletics in 2024. Allen offers an alternative at shortstop to Orlando Arcia, who is coming off a disappointing season, but ultimately Allen should be more of a depth option.

Franco (personal) was arrested in the Dominican Republic on Monday following an altercation Sunday during which guns were drawn, Juan Recio of ESPN.com reports.

Franco is being held for questioning and it's not yet clear whether he faces charges as a result of the incident. The 23-year-old is on MLB administrative leave and is due to stand trial on Dec. 12 in the Dominican Republic involving charges of sexual abuse, sexual exploitation against a minor and human trafficking. If convicted, Franco faces up to 20 years in prison. MLB is also performing a concurrent investigation of Franco under its domestic violence, sexual assault and child abuse policy.
