Krook agreed to a minor-league contract with the Athletics on Saturday.

Krook elected free agency earlier in the month after being sent outright to Cleveland's Triple-A affiliate, and he's since decided to return to the A's. He made three appearances for the Athletics during the 2025 season, surrendering two runs on five hits and one walk while striking out three over 3.1 innings.

Robberse (elbow) signed a minor-league contract with the Cardinals on Monday, which includes an invitation to spring training, Derrick Goold of the St. Louis Post-Dispatch reports.

Robberse was non-tendered by St. Louis on Friday, but the club has since elected to bring him back on a minor-league deal. He's currently rehabbing from Tommy John surgery and is expected to miss the first few months of the 2026 campaign.

The Reds re-signed Spiers (elbow) to a minor-league contract with an invitation to spring training Monday.

Spiers was non-tendered by Cincinnati last week, but he'll remain in the organization on a minor-league pact. The right-hander is expected to miss most, if not all, of the 2026 season after having Tommy John surgery in late July, so it's likely a two-year minor-league contract.

The Cardinals re-signed Pozo to a major-league contract with an invitation Monday.

Pozo was non-tendered by St. Louis last week and is now back in the organization just a few days later. The Cardinals already have Ivan Herrera, Jimmy Crooks and Pedro Pages competing for reps at catcher on the major-league roster, but Pozo will also factor into the mix after coming to terms on a big-league deal. He slashed .231/.262/.375 with five home runs in 67 games for the Cardinals in 2025.

The Rockies signed Mushinski to a minor-league contract with an invitation to spring training Monday, Kevin Henry of The Denver Gazette reports.

Mushinski spent the entirety of the 2025 campaign at Triple-A Columbus in the Guardians organization, holding a 3.78 ERA and 66:33 K:BB over 50 innings. The lefty reliever has made 31 appearances at the big-league level, collecting a 5.45 ERA and 26:12 K:BB across 33 frames. Mushinski will compete for a spot in Colorado's Opening Day bullpen but will likely begin the year at Triple-A Albuquerque.

Long signed with NPB's Chiba Lotte on Sunday.

Long is a 30-year-old right-handed reliever who has played with three teams over five big-league seasons. He was solid in his first year in Kansas City in 2024, posting a 3.16 ERA and 1.20 WHIP along with a 44:17 K:BB over 42.2 innings, but Long struggled to a 5.36 ERA, 1.74 WHIP and 33:22 across 40.1 frames last season. He wasn't likely to get more than a minor-league deal in MLB free agency and has instead opted to try to put things back together overseas.

The Mets are finalizing a trade that will send Nimmo to the Rangers in exchange for infielder Marcus Semien, Jeff Passan of ESPN.com reports.

Nimmo is coming off a 2025 campaign during which he posted a .760 OPS with 25 home runs, 92 RBI and 13 stolen bases over 652 regular-season plate appearances. He also played in a career-high 155 contests and has been relatively durable in recent campaigns, logging at least 151 appearances every year since 2022 despite managing a foot injury. Nimmo should immediately take on a starting role in the Rangers' outfield and will be looked to for some pop, as he's averaged 24 regular-season long balls over the past three years. However, his defense has slipped of late (probably at least in part due to the foot issue), and he has five years remaining on his current deal, which may explain why the Mets decided to move him. Nimmo has a full no-trade clause in his contract, but he's already approved the deal, per Will Sammon of The Athletic.

The Rangers are trading Semien to the Mets in exchange for outfielder Brandon Nimmo, Jeff Passan of ESPN.com reports.

Semien's numbers have been trending down in recent years, and his .669 OPS last season was the lowest mark of his career. However, the 35-year-old still provided a mix of moderate power and speed with 15 homers and 11 stolen bases, and he offers elite defense at second base, as he's coming off winning his second Gold Glove Award. Semien ended the campaign on the 60-day injured list due to a foot injury, but he's expected to have a normal offseason and to be ready for spring training. Nimmo has a full no-trade clause in his contract, but per Will Sammon of The Athletic, the outfielder has already approved the deal.

Atlanta signed Payamps to a one-year, $2.25 million contract Sunday.

Payamps joined Atlanta as a waiver claim in late September and was outrighted to Triple-A on Nov. 6. That move was likely made by the team to avoid an arbitration hearing, as the $2.25 million agreed to by the sides Sunday is probably less than what the veteran reliever would have received in arbitration. Regardless, Payamps now seems ticketed for a role in Atlanta's bullpen in 2026. He's had plenty of major-league success but will be looking to rebound from a career-worst 2025 campaign during which he posted a 6.84 ERA, 1.52 WHIP and 24:9 K:BB over 26.1 innings across 30 appearances between Atlanta and Milwaukee.

Laskey agreed to a minor-league contract with the Rockies on Sunday, Aram Leighton of JustBaseball.com reports.

Laskey spent 2025 in the Marlins organization and split his time between the Double-A and Triple-A levels. He received an invitation to big-league spring training but is likely to open 2026 in the minors based on his production last year and the fact that he's yet to make his MLB debut.
