Aaron Civale RP | CHC
Athletics' Aaron Civale: Lands in Sacramento
Civale agreed to a one-year $6 million contract with the A's on Tuesday, Jon Heyman of the New York Post reports.
The 30-year-old right-hander split the 2025 campaign between the Brewers, White Sox and Cubs, finishing the regular season with a 4.85 ERA, 1.26 WHIP and 88:33 K:BB across 102 innings. Civale started in 18 of those 23 appearances last year and is a safe bet to work out of the Athletics' rotation, providing another veteran presence in a unit that's unsettled at the back end.

Jason Adam RP | SD
Padres' Jason Adam: Could be back by mid-April
Adam (quadriceps) could be ready for his season debut "by mid-April or thereabouts," AJ Cassavell of MLB.com reports.
Adam is working his way back from left quadriceps tendon repair surgery, which he had last September. The Padres anticipate the veteran reliever throwing off a mound during spring training, and he could be ready for a rehab assignment around Opening Day. Once healthy, Adam will be a top setup man to closer Mason Miller.

Sung-Mun Song 2B | SD
Padres' Sung-Mun Song: Projected for utility role
The Padres expect Song to be used in a utility role this season, AJ Cassavell of MLB.com reports.
Inked to a four-year, $15 million contract in December, Song primarily played third base during his time with the Kiwoom Heroes of the Korea Baseball Organization. However, he also has ample experience at second and first base, and the Padres will try him out in the outfield, as well. Additionally, Song will compete with Miguel Andujar for playing time at designated hitter.

Packy Naughton RP | STL
Cardinals' Packy Naughton: Ready to go at start of spring
Naughton (elbow) will not have any restrictions at the beginning of spring training, Jeff Jones of the Belleville News-Democrat reports.
Naughton missed all of 2025 and most of 2024 due to a pair of elbow surgeries, first to repair a flexor strain and later to fix a torn UCL. He's finally fully healthy and is in camp as a non-roster invitee to compete for a spot in the Cardinals' bullpen. Naughton held a 4.14 ERA and 36:8 K:BB over 37 frames from 2022-2023 with St. Louis.

Bryce Eldridge DH | SF
Giants' Bryce Eldridge: Fully recovered from wrist surgery
Eldridge said Tuesday that he's full-go at the start of spring training after surgery in October to remove a bone spur from his left wrist, Justice delos Santos of The San Jose Mercury News reports.
Eldridge got a late start to last season after hurting his wrist in spring training, and, after playing with the injury for several months, it was eventually decided an operation was needed. The 21-year-old is tentatively penciled in as the Giants' designated hitter, though he will have to earn that gig with a strong showing during Cactus League play. Eldridge went just 3-for-28 during his brief time with the Giants last season and slashed .260/.333/.510 with 25 homers over 102 games in the minors last year.

A.J. Puk RP | ARI
Diamondbacks' A.J. Puk: Expects to be back before July
Puk (elbow) said Tuesday that he expects to be ready for his season debut before July, Alex Weiner of ArizonaSports.com reports.
Puk had an internal brace procedure last June rather than a full Tommy John repair of his UCL injury. The less invasive surgery gives him a chance at a quicker return, so a season debut before the All-Star break is possible. The left-hander expects to be cleared to throw off a mound by the end of March, and a clearer picture of his timetable could be available around that time. Puk will have a good shot to assume the closer role in Arizona when he does return, as the Diamondbacks bullpen lacks established options.

Diamondbacks' Corbin Burnes: Aims for mound work in late spring
Burnes (elbow) expects to throw off a mound by the end of spring training, Jack Sommers of SI.com reports.
Burnes also reiterated his goal of making his season debut around the All-Star break. The veteran right-hander is working his way back from Tommy John surgery, which he had last June. A midseason return would appear to be a best-case scenario for Burnes, who is entering the second year of a six-year, $210 million contract.

Marcelo Mayer 3B | SF
Red Sox's Marcelo Mayer: Position to be determined
Mayer's starting position has yet to be determined, Jen McCaffrey of The Athletic reports. He played both second base and third base during his rookie season in 2025.
Mayer had been ticketed for a starting role at third base, replacing the departed Alex Bregman, but Monday's acquisition of Caleb Durbin from Milwaukee creates uncertainty. Both Mayer and Durbin have experience at the hot corner and second base in the majors, and manager Alex Cora was hesitant to make any decisions Monday. An early indicator of the infielders' eventual landing spot should come Feb. 15, when Boston's position players report to Fort Myers and where the two are stationed during spring training drills.

Justin Martinez RP | ARI
Diamondbacks' Justin Martinez: Aiming for late August return
Martinez (elbow) hopes to make his season debut by late August, Jack Sommers of SI.com reports.
Recovering from Tommy John surgery that he had last June, Martinez began a throwing program in mid-January. He will continue with a deliberate pace to his rehab and likely begin a rehab assignment a little after the All-Star break if all goes well. Martinez had been serving as the Diamondbacks' closer before getting hurt, but he could retake his old gig late in the 2026 campaign.

Brooks Lee 3B | MIN
Twins' Brooks Lee: Leading candidate for shortstop
Lee is the favorite to start at shortstop for the Twins but must show improved range and more consistent offense, Dan Hayes of The Athletic reports.
Lee took over as the everyday shortstop last season after Carlos Correa was traded, but he struggled at the position defensively. The Twins have very little depth behind Lee at shortstop, so they have little choice but to throw him out there and hope for improvement with the glove. If Lee falters, Ryan Kreidler and Orlando Arcia would be next in line at shortstop for Minnesota.
