Mayer (wrist) is expected to be ready for Opening Day, Lauren Campbell of MassLive.com reports.

Mayer is recovering from right wrist arthroscopy performed in August that ended his season after 44 games. He potentially could have played in the postseason had Boston extended its run, and Mayer is expected to be available for spring training. Depending on roster additions, the 23-year-old infielder could end up playing second base, shortstop or third base. He mainly played at the hot corner in his big-league debut, but a downturn in shortstop Trevor Story's defense (minus-9 OAA) in 2025 could allow Mayer to return to his natural position, which would allow Story to shift to second

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.

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 Pirates designated Cheng for assignment Friday, Kevin Gorman of TribLive.com reports.

The Pirates needed to clear some roster space after bringing in three players via a three-team trade with Houston and Tampa Bay on Friday, and Cheng will end up as one of the casualties. The 24-year-old infielder made his MLB debut near the beginning of last season, going 0-for-7 with three strikeouts before being sent back to the minors. He didn't fare well at the plate in Triple-A either, slashing .209/.310/.271 with 36 RBI, 37 runs scored and 18 steals across 398 plate appearances at Indianapolis.

Vasquez (undisclosed) signed a minor-league contact with the Orioles on Wednesday that includes an invitation to spring training, Andy Kostka of TheBaltimoreBanner.com reports.

Vasquez hit .256/.297/.359 with two homers and six steals over 44 contests at Double-A Montgomery in the Rays organization before missing the final three months with an undisclosed injury. It's unclear what his current health status is, but the infielder will be part of big-league spring training with the Orioles.

The Rangers signed Velazquez to a minor-league contract Dec. 8.

Velazquez spent all of this past season at Triple-A Scranton/Wilkes-Barre in the Yankees organization, slashing .242/.304/.345 with five homers and 25 steals. A career .189/.244/.293 hitter over parts of six big-league seasons, Velazquez will give the Rangers some experienced infield depth at Triple-A Round Rock.

Kim signed a one-year, $20 million contract with Atlanta on Monday, Jon Heyman of the New York Post reports.

Kim finished out the 2025 campaign with Atlanta after being claimed off waivers, and he did enough to earn himself another look with the club in 2026. He slashed .253/.316/.368 with three home runs, 12 RBI and 14 runs scored in 24 games down the stretch of the 2025 season after being dumped by the Rays. Kim figures to see the bulk of his playing time at shortstop heading into the upcoming season, though he can also manage at the keystone if necessary. Mauricio Dubon is expected to be deployed as a true utility man following the addition of Kim.

The Angels acquired Grissom from the Red Sox on Tuesday in exchange for Isaiah Jackson, Chris Cotillo of MassLive.com reports.

Grissom had a forgettable tenure in Boston after being sent there from Atlanta in the Chris Sale trade. He slashed only .190/.246/.219 with zero home runs over 31 games during the 2024 season before spending all of 2025 at Triple-A Worcester, where he slashed .270/.342/.441 with 13 home runs. Grissom -- who will turn just 25 in January -- is out of minor-league options and will get a fresh start with the Angels. Most of Grissom's experience has come in the middle infield, but he's also handled third base, first base and left field.

The Yankees do not expect Volpe (shoulder) to be ready for his season debut before the end of April, Bryan Hoch of MLB.com reports.

Volpe underwent surgery in mid-October to repair a partially torn labrum in his left shoulder. He is expected to be cleared to hit by February but will not be allowed to dive on the shoulder until around April. It's possible Volpe will be ready to go by early May, but a clearer picture of his timetable should be available at a later date. Jose Caballero is in line to serve as the Yankees' primary shortstop until Volpe is ready.

The Pirates claimed Luciano off waivers from the Giants on Friday, Kevin Gorman of TribLive.com reports.

Luciano was one of the top prospects in baseball a few years ago, but he has not progressed as hoped, slashing just .217/.286/.304 over 41 games in the majors and .227/.351/.401 at the Triple-A level. He's still just 24, though, so the Pirates felt he was worth a roll of the dice. Luciano -- who does not have minor-league options remaining -- has primarily been a shortstop but shifted to left field at Triple-A Sacramento in 2025. It's unclear at this point what position the Pirates have planned for him.
