The Reds selected Arroyo's contract from Double-A Chattanooga on Tuesday, Francys Romero of BeisbolFR.com reports.

Arroyo slashed .284/.345/.371 with three home runs and 12 stolen bases over 120 games with Chattanooga in 2025 after missing the 2024 campaign due to shoulder labrum surgery. The 22-year-old is now on the 40-man roster and could move up to Triple-A Louisville to begin the 2026 season.

The Mets designated Montas (elbow) for assignment Tuesday, Michael Mayer of MetsmerizedOnline.com reports.

The club needed to free up a spot on its 40-man roster ahead of Tuesday's Rule 5 protection deadline. Montas posted a 6.28 ERA in seven starts and two relief appearances in 2025 and is slated to miss the entire 2026 season while recovering from Tommy John surgery. He will become a free agent after clearing waivers and the Mets will be responsible for his $17 million salary for next season.

The Red Sox designated Winckowski (elbow) for assignment Tuesday, Chris Cotillo of MassLive.com reports.

The move frees up a spot on Boston's 40-man roster. Winckowski made just six appearances for the Red Sox in 2025, as he spent time in the minors and also missed a large chunk of action with a flexor strain. It's unclear what Winckowski's current health status is. The 27-year-old has a career 4.20 ERA and 195:89 K:BB across 242.1 innings.

The Red Sox designated Lowe for assignment Tuesday.

Lowe had been set to be non-tendered later this week, so this transaction just serves a way to remove him from the 40-man roster sooner. The veteran first baseman slashed only .228/.307/.381 with 18 home runs over 153 regular-season games between the Nationals and Red Sox in 2025. Lowe will become a free agent once he officially clears waivers.

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.

The Mets selected Morabito's contract from Double-A Binghamton on Tuesday, Will Sammon of The Athletic reports.

Morabito spent all of the 2025 campaign at Binghamton, slashing .273/.348/.385 with six home runs and 49 stolen bases over 118 contests. The 22-year-old can play all three outfield spots and has logged 130 steals in 300 pro games. Morabito is now protected from the Rule 5 Draft.

The Pirates are "strongly considering" giving Griffin the opportunity to win their starting shortstop job, Jeff Passan of ESPN.com reports.

The No. 9 overall pick in the 2024 First-Year Player Draft, Griffin slashed .333/.415/.527 with 21 home runs and 65 stolen bases across three levels in 2025 in his first professional season, finishing the year at Double-A Altoona. Griffin will not turn 20 until late April, and the last teenage position player to debut in the big leagues was Juan Soto in 2018. The Pirates have a clear opening at shortstop, though, and the organization is sending signals that it wants to surround ace Paul Skenes with more talent. Griffin's stock in redraft leagues will soar if it looks like the Pirates will indeed give him a real chance to crack the Opening Day roster.

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.

The Diamondbacks outrighted Montes De Oca (back) to Triple-A Reno on Monday.

The transaction frees up a spot on the Diamondbacks' 40-man roster. Montes De Oca is recovering from surgery to repair a stress fracture in his back and it's not clear when he will be ready to pitch again. The reliever tossed 2.2 scoreless frames in his lone appearance for Arizona in 2025 and held a 4.07 ERA and 26:6 K:BB over 24.1 innings at Triple-A Reno.
