Nunez was outrighted to Triple-A Columbus by the Guardians and elected free agency Thursday, Tim Stebbins of MLB.com reports.

Nunez had a very brief stint in the majors in early June, but he otherwise spent his season in Columbus. He could get a minor-league deal elsewhere this winter.

Atlanta outrighted Robinson to Triple-A Gwinnett on Thursday.

He'll have the opportunity to elect free agency if he wants. Robinson holds a career .131/.169/.192 slash line over 138 plate appearances in parts of three seasons in the majors.

The Blue Jays selected Valenzuela's contract from Triple-A Buffalo on Thursday.

Valenzuela is now protected from next month's Rule 5 Draft. Acquired at the trade deadline from the Padres in exchange for Will Wagner, Valenzuela slashed .224/.309/.383 with 15 home runs over 113 games between the Double- and Triple-A levels in 2025. The 25-year-old will likely begin the 2026 campaign back at Buffalo.

The Marlins outrighted Navarreto to Triple-A Jacksonville on Wednesday.

Having been outrighted before, Navarreto can reject Wednesday's outright assignment and become a free agent if he wants. The catcher went 4-for-14 at the dish during his brief time with Miami in 2025.

The Rangers claimed MacIver off waivers from the Athletics on Wednesday.

MacIver got his feet wet at the big-league level in 2025, slashing .186/.252/.324 over 32 games for the Athletics. The Rangers have Jonah Heim and Kyle Higashioka slated to handle catching duties in 2026, so MacIver is merely a depth addition.

The Giants declined Murphy's (back) $4 million team option for 2026 on Monday, Maria Guardado of MLB.com reports.

Murphy received a $250,000 buyout and will take home $8.25 million over his two-year stay with the Giants, during which he appeared in just 13 games. He didn't play after early May of the 2024 season after suffering a knee sprain, then missed the entire 2025 campaign due to a mid-back disc herniation that cropped up during spring training. The Giants didn't provide a clear indication on where Murphy stood in his rehab program before the end of this past season, making it uncertain if he'll be healthy in advance of spring training. If the 34-year-old backstop elects to continue his playing career in 2026, he'll likely have to settle for a minor-league deal.

The Padres declined Diaz's (oblique) $7 million club option for 2026 on Tuesday, Jeff Sanders of The San Diego Union-Tribune reports.

Diaz posted a .607 OPS across 283 regular-season plate appearances in 2025 -- his worst mark since 2019. Rather than pay him $7 million to likely act as a backup in 2026, the Friars will instead give the 34-year-old a $2 million buyout and send him into free agency. His defense should still be enough for him to draw interest from other clubs, but he doesn't offer much fantasy upside at this stage in his career.

Perez signed a two-year, $25 million contract extension with the Royals on Tuesday.

Perez had a $13.5 million team option for 2026, but his new deal will slightly decrease his AAV while ensuring the veteran backstop remains in Kansas City through 2027. Perez's .236 batting average from 2025 was the second-lowest mark of his 15-year MLB career, but he also finished the season with 30 homers for the first time since 2021 and 100 RBI for the third time in five years.

Contreras underwent a minor procedure on his fractured left middle finger Tuesday, Adam McCalvy of MLB.com reports.

General manager Matt Arnold said Contreras is roughly 5-to-6 weeks away from resuming baseball activity, so his surgery isn't expected to affect Contreras' availability for the start of the 2026 season. The 27-year-old backstop also had his $12 million club option declined Tuesday after posting a .754 OPS in the regular season -- his worst as a Brewer. However, he will remain under team control as an arbitration-eligible player.

The Brewers declined Contreras' $12 million option for 2026.

Contreras will receive a $100,000 buyout instead, and he remains under team control for 2026 and 2027 as an arbitration-eligible player. The catcher slashed .260/.355/.399 with 17 home runs over 150 regular-season games for the Brewers in 2025. Contreras was scheduled to visit a hand specialist last week to determine whether he needs surgery to repair a fractured left middle finger, but there's no word on whether an operation is required. Even if he does have surgery, his availability for spring training is not expected to be in peril.
