The Red Sox acquired Gray from the Rays in exchange for Luis Guerrero on Tuesday.

Gray has managed a .207/.264/.369 batting line over parts of three big-league seasons. He can handle all four infield positions and will join Boston's 40-man roster.

The Rays acquired Guerrero from the Red Sox on Tuesday in exchange for Tristan Gray.

Guerrero was outrighted off Boston's 40-man roster last week after passing through waivers unclaimed, but now he's on the move to a new organization. The right-hander holds a 2.63 ERA but a 19:16 K:BB across 27.1 frames covering parts of two major-league seasons. Guerrero has a big arm and the Rays will now be tasked with getting him to throw more strikes, which is something they've had success with as an organization with other hurlers.

Altuve underwent a procedure to remove fluid between the fourth and fifth toes on his right foot Monday, Brian McTaggart of MLB.com reports.

Altuve played through the issue for the final few weeks of the regular season after suffering the injury Sept. 13 against Atlanta. McTaggart described the procedure as a minor skin aspiration, and the expectation is that the 35-year-old will be ready for the start of spring training.

Astros general manager Dana Brown said during last week's general managers' meetings that Paredes was about 65 percent recovered from his right hamstring injury, Brian McTaggart of MLB.com reports.

Brown added that he's hopeful Paredes will be 80-to-90 percent recovered by spring training and potentially be ready to go by Opening Day. Paredes missed two months due to a right hamstring tear suffered in mid-July before making a late-season return, though he was limited to designated hitter duty and severely compromised as a baserunner. The 26-year-old will continue to rehab the injury and it sounds like he'll be slow-played at the start of spring training.

Arrighetti (elbow) is expected to be 100 percent for the beginning of spring training, Matt Kawahara of the Houston Chronicle reports.

Arrighetti missed the final month of the season with a right elbow injury, but he's considered healthy now and is "having a very productive offseason," per Astros general manager Dana Brown. The 25-year-old was limited to only seven starts at the major-league level in 2025, as he was sidelined four months with a right thumb fracture in addition to the elbow issue. Brown indicated that Arrighetti has a rotation spot for 2026 locked up.

Ortiz was traded from the Dodgers to the Mariners in exchange for minor-league pitcher Tyler Gough (elbow) on Sunday, Fabian Ardaya of The Athletic reports.

Ortiz was just added to Los Angeles' 40-man roster Nov. 6, but he will now head to the Mariners organization. The left-hander began the 2025 campaign with Single-A Rancho Cucamonga, but he was able to work his way all the way up to Triple-A Oklahoma City, posting a 2.76 ERA with 14 strikeouts over 15 appearances, including one start, with OKC. Ortiz will look to compete for a spot in the major-league bullpen when Seattle regroups at spring training in February.

Naylor and the Mariners are finalizing a five-year contract Sunday, pending a physical, Jeff Passan of ESPN.com reports.

Naylor will remain with Seattle after being traded to the team from Arizona in late July. The first baseman compiled a .295/.353/.462 slash line while producing 20 home runs, 92 RBI, 81 runs scored and a career-high 30 stolen bases over 147 regular-season contests with the Diamondbacks and Mariners in 2025. Naylor registered a .299 average with nine homers and 33 RBI in 54 regular-season games with Seattle. The 28-year-old will now hold down the first-base position for the team for a half-decade moving forward.

Fitts (arm) heads into the winter with no limitations, Christopher Smith of MassLive.com reports.

Fitts, who missed the final 30 games of the season due to right arm neuritis, is throwing again and should have a normal offseason, per Boston chief baseball officer Craig Breslow. Injuries to projected rotation members during the spring opened a spot for Fitts early on before he landed on the IL with a pectoral strain. Pending the team's offseason moves -- re-sign Lucas Giolito or add a viable free agent -- Fitts will be part of a group competing for a spot at the back end of the rotation or the bullpen.

Meneses signed a minor-league contract with the Athletics on Saturday, Francys Romero of BeisbolFR.com reports.

Meneses spent the entire 2025 campaign with the Mets' Triple-A affiliate, slashing .264/.321/.444 with 11 homers, 55 RBI and 37 runs scored across 421 plate appearances. Signing with the Athletics figures to give the 33-year-old a higher chance of returning to the majors compared to New York, though he is still likely to spend most of his time at Triple-A Las Vegas.

Sandlin (elbow) cleared waivers Saturday and was sent outright to Triple-A Buffalo, Ben Nicholson-Smith of Sportsnet.ca reports.

Sandlin was effective in the big leagues in 2025, turning in a 2.20 ERA and 1.16 WHIP across 16.1 regular-season innings with the Jays. However, right elbow inflammation sent him to the injured list in early July, and multiple setbacks in his recovery prevented him from returning. The 28-year-old righty will likely elect free agency and could attract significant attention after posting a 3.19 ERA through his first five MLB seasons.
