The Yankees designated Shewmake for assignment Thursday.

The move frees a spot on the 40-man roster for waiver claim Osvaldo Bido. Shewmake spent all of the 2025 season at Triple-A Scranton/Wilkes-Barre, slashing .244/.318/.362 with four homers and 15 steals in 85 games. The 28-year-old infielder does not have minor-league options remaining, which will likely affect his appeal on waivers.

The Mariners could give Emerson more seasoning at Triple-A Tacoma following the acquisition of Brendan Donovan, Daniel Kramer of MLB.com reports.

Emerson will compete with Cole Young for a spot in the Mariners' lineup, but Young is considered the heavy favorite for the second-base job entering camp. The 20-year-old Emerson reached Tacoma in 2025, finishing with a .285/.383/.458 batting line with 16 home runs and 14 stolen bases over 130 games covering three levels of the minors. He should get an opportunity at the big-league level at some point during the 2026 campaign.

Young "would have to struggle mightily to lose his grip on the second-base job," Daniel Kramer of MLB.com reports.

New acquisition Brendan Donovan's primary position has been second base, but he will enter spring training slated to see most of his action in 2026 at third base. Young put up just a .607 OPS in 257 plate appearances during his rookie season, but he is only 22 and the Mariners remain high on his long-term potential. If Young stumbles, Seattle could consider shifting Donovan over to second base and installing Colt Emerson at the hot corner.

Genao showed more full extension on his swings while with Aquilas in the Dominican Winter League, Keith Law of The Athletic reports.

Genao suffered a right shoulder injury during spring training last year, and the effects of the injury lingered throughout the regular season. After a boffo 2024, the 21-year-old shortstop dropped to a .259/.323/.359 slash line over 77 games at Double-A Akron. In winter ball, Genao improved to .325/.387/.386 over 26 games for Aquilas, suggesting he regained strength and confidence in the shoulder. He might eventually move to second base in the majors, but his improved defense at Akron in 2025 suggest shortstop is still a possibility. Genao's a bounce-back candidate for 2026 and expected to reach Triple-A Columbus.

Red Sox manager Alex Cora noted at Fenway Fest in January that he envisions Mayer getting more playing time against left-handers in 2026, Jen McCaffrey of The Athletic reports.

Mayer was allotted 27 of 136 plate appearances at the MLB level against lefties in 2025, managing a miniscule .416 OPS in the small sample size. With the departure of Alex Bregman, it's likely Mayer will take over at third base this season, and Cora wants a more full-time role for the 23-year-old infielder, who is capable of slotting in at three infield positions. Boston's recent signing of Isiah Kiner-Falefa, a Gold Glove winner at third base in 2020 while with Texas, could impact the eventual infield positioning, but he appears ticketed for a rotation at second base with several other candidates.

The Tigers have extended McGonigle an invitation to big-league camp during spring training.

Fellow top prospects Max Clark, Max Anderson and Jose Briceno, among others, will also be in major-league camp. Arguably the top prospect in all of baseball, McGonigle is an extremely advanced hitter at just 21 years of age, having slashed .305/.408/.583 with 19 home runs, 10 stolen bases and a 59:46 BB:K across 88 games covering three levels in 2025. He can handle shortstop, second base and third base, and it's at shortstop where the left-handed batter has the clearest opening for playing time with the big club. The Tigers might not be ready to carry McGonigle on their Opening Day roster, but he should make an impact at some point during the 2026 season.

The Yankees outrighted Luciano to Triple-A Scranton/Wilkes-Barre on Tuesday.

After bouncing around via waivers for the past two months, Luciano cleared this time and will remain in the Yankees organization. The 24-year-old has managed just a .217/.286/.304 batting line over 41 games in the majors.

The Athletics signed Wilson to a seven-year, $70 million contract extension Friday, Jeff Passan of ESPN.com reports. The deal includes a club option for 2033.

Wilson finished runner-up to teammate Nick Kurtz in the American League Rookie of the Year voting in 2025 after slashing .311/.355/.444 with 13 home runs, five stolen bases and a 27:39 BB:K over 125 contests in his first full major-league season. The 23-year-old's upside is capped due to his lack of power and mediocre defense at shortstop, but Wilson has some of the best contact skills in the game. It's a contract that should turn out to be very team-friendly as long as he stays healthy.

The Mariners have extended Emerson an invitation to major-league camp during spring training.

Fellow top prospects Kade Anderson, Lazaro Montes and Ryan Sloan, among others, will join the 20-year-old infielder in big-league camp. Emerson has the best opportunity of all of them to break camp with the big club, as he is expected to be in the thick of the competition for the Mariners' third-base job. He slashed .285/.383/.458 with 16 home runs and 14 stolen bases over 130 games covering three levels of the minors in 2025.

Wilson said earlier this month that adding strength has "been the main focus for the last couple of offseasons now," Martin Gallegos of MLB.com reports.

Wilson showed a little more pop than expected in 2025, slugging 13 home runs. Power is considered the weakest part of his offensive game, though, so he's working on adding a little bulk this winter. Still, fantasy managers should consider it a bonus if they get double-digit home runs out of Wilson again in 2026, as he is most likely to provide an elite batting average but not much else.
