Arroyo will begin transitioning from second base to left field this month during the Columbian Winter League, Adam Jude of the Seattle Times reports.

Arroyo played second base exclusively in 2025 between High-A Everett and Double-A Arkansas, slashing .262/.401/.433 with 17 homers and 12 steals between the two stops. He has never played the outfield before, but with the Mariners' infield depth, the organization has elected to move the 21-year-old to left field. Arroyo could push to debut at some point during the 2026 season.

Young is the leading candidate to start at second base for the Mariners next season, Adam Jude of the Seattle Times reports.

Young's playing time tapered off for the Mariners down the stretch of the regular season and he did not play during the playoffs. However, Seattle remains high on the 22-year-old's potential despite a .211/.302/.305 batting line in 77 games this season. The Mariners could acquire a second baseman from outside the organization, but if they don't, the left-handed-hitting Young is the top candidate to start at least against righties. Leo Rivas and Ryan Bliss (knee) will also be in the mix.

Manoah signed a one-year, $1.95 million contract with the Angels on Tuesday, Jeff Passan of ESPN.com reports.

Manoah missed the majority of the 2025 season while working his way back from an elbow procedure he underwent in June 2024. Once healthy, the 27-year-old righty remained with the Blue Jays' Triple-A affiliate, where he turned in a 2.97 ERA and 1.36 WHIP in 33.1 innings over seven starts. Now with the Halos, he'll have a much greater chance of returning to the majors in 2026, as the Angels' rotation finished last in the American League with a 4.91 ERA this past season.

Jax, Garrett Cleavinger and Edwin Uceta are expected to be part of a closer-by-committee for the Rays in 2026, Marc Topkin of the Tampa Bay Times reports.

There's been some talk of Jax potentially stretching out to join the Rays' rotation, but the current plan is to leave the 31-year-old in the bullpen. Acquired from the Twins at the trade deadline, Jax had an elevated 4.23 ERA in 2025, but a 2.51 FIP and 35 percent strikeout rate were more indicative of how he pitched. Mason Montgomery, Bryan Baker, Hunter Bigge, Steven Wilson and Manuel Rodriguez (elbow) could also work their way into high-leverage work, but the tentative plan seems to be for Jax, Cleavinger and Uceta to share the closer role.

Uceta, Garrett Cleavinger and Griffin Jax are expected to be part of a closer-by-committee for the Rays next season, Marc Topkin of the Tampa Bay Times reports.

Pete Fairbanks easily paced the Rays with 27 saves in 2025, but he is a free agent after the team declined his $11 million option. That leaves a vacancy in the ninth inning, and it seems the Rays plan to fill that void with multiple arms. Uceta finished with a 3.79 ERA in 2025, but he had a 32.1 percent strikeout rate and boasts a 33.3 percent strikeout rate in his two seasons with Tampa Bay.

Cleavinger, Griffin Jax and Edwin Uceta are expected to be part of a closer-by-committee for the Rays in 2026, Marc Topkin of the Tampa Bay Times reports.

The Rays elected to decline Pete Fairbanks' $11 million option, and the plan for now is to fill that ninth-inning vacancy with multiple players. Cleavinger had the best season of his career in 2025, holding a 2.35 ERA and 82:18 K:BB over 61.1 innings. The lefty has neutral splits, so he should not be at a matchup disadvantage when it comes to who manager Kevin Cash chooses to deploy in save situations.

The Cubs are currently projecting regular playing time for Caissie next season, Patrick Mooney of The Athletic reports.

The club would also like to give Moises Ballesteros a chance to play regularly, though one of Caissie, Ballesteros and Seiya Suzuki will have to sit out most days. Caissie has nothing left to prove at Triple-A Iowa, having slashed .281/.380/.507 there over the last two seasons. He struggled in a cup of coffee with the Cubs, going 5-for-26 with 11 strikeouts, but is viewed as the team's top prospect.

Schmitt underwent surgery on his left wrist Tuesday and was given a rehab timeline of 8-to-10 weeks, Alex Pavlovic of NBC Sports Bay Area reports.

The 26-year-old could be limited for the start of spring training in February but should have plenty of time to get back to full health before Opening Day. Schmitt played in 95 games for the Giants last season and clubbed 12 home runs with a .237/.305/.401 slash line in 348 plate appearances. He should be in the mix to start at second base to begin 2026 but is likely better suited for more of a utility role.

Atlanta signed Young (elbow) to a one-year contract Tuesday.

It's a split contract for Young, who will miss at least the first half of the 2026 season while recovering from Tommy John surgery. The left-handed reliever holds a career 4.01 ERA and 78:25 K:BB over 60.2 innings covering parts of four major-league seasons, which includes stints in Atlanta in 2022 and 2023.

Williams agreed to a three-year contract with the Mets on Monday, Will Sammon of The Athletic reports.

Williams will remain in New York but is headed to Queens following Monday's signing. The 31-year-old had his fair share of struggles with the Yankees during the 2025 campaign, ending the year with four blown saves in 22 chances and ultimately losing his grip on the closer's role. He finished the regular season with a 4.79 ERA and 1.13 WHIP with a 90:25 K:BB across 62.0 frames. Williams will receive a fresh start with the Mets on a deal that will guarantee him more than $50 million, per Jeff Passan of ESPN.com.
