Matthews is still viewed as a second baseman long term, but he'll also play in the outfield in 2026, Brian McTaggart of MLB.com reports.

"He's going to get some run in the outfield, but second base is still going to be his main position," general manager Dana Brown said. "We project he'll turn the corner with the bat and get maybe some run in the outfield a little bit, as well." Matthews is situated as a backup option at shortstop and second base, and he would need an injury to Jeremy Pena or Jose Altuve to see significant work in the middle infield in 2026. The Astros probably aren't done making moves this offseason either and could add more outfield options, but Brown and manager Joe Espada were complimentary about Matthews' potential in the short term and long term. Matthews is a great athlete with plus speed and above-average raw power. He slashed .260/.371/.458 with 17 home runs, 41 steals and a 27.9 percent strikeout rate in 112 games in the Pacific Coast League. A .167 BABIP and 42.6 percent strikeout rate led to a .167 batting average and .222 on-base percentage in the majors, but he showed off his tools with four home runs and one steal in 13 games.

Tiedemann (elbow) is expected to be fully healthy in time for camp, Keegan Matheson of MLB.com reports.

Tiedemann missed the entire 2025 season after undergoing Tommy John surgery in July of 2024, and he has totaled just 140 innings in the minors since being drafted by Toronto in 2021. Despite that, it was still an easy call for the Blue Jays to add Tiedemann to the 40-man roster in November for Rule 5 protection. While the hard-throwing lefty has flashed high upside and is close to full health, Tiedemann is highly unlikely to handle a big workload in 2026 given all the missed time. "Hopefully he's a factor for us in our rotation," GM Ross Atkins said. "That's the plan, but we would be open to him impacting the team in a bulk role or some creative way, depending on how things are going."

The Athletics signed Soderstrom to a seven-year, $86 million contract extension Thursday, Jeff Passan of ESPN.com reports. The deal includes a club option for 2033.

The deal buys out at least three free-agent years and can max out at $131 million if Soderstrom reaches all of the escalators in the contract. Soderstrom broke out in 2025 in his first full major-league season, slashing .276/.346/.474 with 25 home runs and 93 RBI. He also learned to play left field on the fly and took to it surprisingly well, finishing as a Gold Glove finalist. Soderstrom will be only 31 in the final year of the contract if the Athletics pick up his option, so it's a deal that is likely to be very team-friendly if he continues his upward trajectory.

The White Sox designated Rolison for assignment Tuesday.

The transaction frees up a spot on the 40-man roster for Sean Newcomb, who was signed Tuesday. Rolison was a waiver claim of the White Sox earlier this month and will now be up for grabs on waivers again. He held a 7.02 ERA and 25:20 K:BB over 42.1 innings with the Rockies in 2025.

The White Sox signed Newcomb (elbow) to a one-year, $4.5 million contract Tuesday.

Newcomb was terrific as a full-time reliever after being traded to the Athletics last season, collecting a 1.75 ERA and 50:14 K:BB over 51.1 innings. The left-hander will get an opportunity to start in Chicago, per Will Sammon of The Athletic, though he could eventually shift back to a relief role. Newcomb's 2025 campaign ended prematurely due to left elbow inflammation, but he should be ready to go for spring training.

Young is expected to see the majority of playing time at second base for the Mariners in 2026 even if the team acquires a second baseman from outside the organization, Ken Rosenthal and Will Sammon of The Athletic report.

The Mariners remain very high on Young even after he had just a .607 OPS in 257 plate appearances during his rookie season. Young is just 22, but the Mariners appear committed to giving him some leash in the majors in 2026. It seemingly makes a trade for Ketel Marte unlikely, and if Brendan Donovan is acquired, he would be in line to see the bulk of his reps at a position other than second base.

The Mariners signed Refsnyder to a one-year, $6.25 million contract Monday, Chris Cotillo of MassLive.com reports.

Refsnyder slashed a robust .312/.407/.516 versus left-handed pitching during his four seasons with the Red Sox, and it should be against southpaws that he sees most of his playing time with the Mariners. He's capable of handling all three outfield spots, and while Refsnyder does have past infield experience, he hasn't played on the dirt regularly since 2017.

The Athletics designated Waldichuk for assignment Monday.

The move frees up a spot on the 40-man roster for the addition of Jeff McNeil (shoulder), who was acquired via trade. Waldichuk missed all of 2024 and the first half of 2025 while recovering from Tommy John surgery, and he posted an 8.65 ERA, 2.06 WHIP and 64:42 K:BB across 51 innings this past season at Triple-A Las Vegas. The lefty will turn 28 in January and hasn't pitched in the majors since 2023, but with a career 33.9 percent strikeout rate in the minors and team control through 2029, he could draw interest via trade or waivers.

The Athletics acquired McNeil (shoulder) and cash considerations from the Mets on Monday in exchange for Yordan Rodriguez, Jeff Passan of ESPN.com reports.

McNeil finished the 2025 season with a .243/.335/.411 batting line and 12 home runs over 462 plate appearances, which was his best offensive season since he made the All-Star team and won the National League batting title in 2022. He underwent thoracic outlet surgery after this past season but is expected to be ready for spring training. Slated to turn 34 just after Opening Day, McNeil will take over as the Athletics' starting second baseman and will get a boost with a move from Citi Field to Sutter Health Park.

The Tigers re-signed Mattison to a minor-league contract Dec. 18 that includes an invitation to spring training, Evan Petzold of the Detroit Free Press reports.

Mattison was non-tendered by the Tigers last month, but he's now back in the organization and will be in big-league camp this spring. The righty reliever boasts a 32.8 percent strikeout rate in the minors but has been held back by a bloated 13.4 percent walk rate.
