Marquez signed a one-year contract with the Padres on Saturday, Alden Gonzalez of ESPN.com reports.

Marquez struggled mightily during his first full season back from Tommy John surgery, finishing 2025 with an unsightly 6.70 ERA and 1.71 WHIP over 126.1 innings with the Rockies. Leaving the pitcher-unfriendly environment of Colorado should help to improve the 30-year-old's numbers, but he still likely faces an uphill battle to make the Padres' rotation.

Chafin signed a minor-league contract with the Twins on Saturday that includes an invite to big-league spring training, Dan Hayes of The Athletic reports.

Chafin turned in a 2.41 ERA over 33.2 innings with the Nationals and Angels in 2025, though his 1.43 WHIP suggests that a handful of lucky breaks helped to prevent runs from scoring against him. Minnesota's bullpen competition is wide open, so the left-hander could land an Opening Day roster spot with a strong Grapefruit League showing.

Manager Torey Lovullo said Saturday that Kelly will start the Diamondbacks' March 26 season opener versus the Dodgers in Los Angeles, Nick Piecoro of The Arizona Republic reports.

The 37-year-old entered camp as the favorite for the Opening Day nod, but the re-signing of Zac Gallen on Friday made the decision less obvious. Kelly posted a 3.22 ERA and 1.06 WHIP over 128.2 innings with Arizona last season but failed to match that production after being traded to Texas, where he put up a 4.23 ERA across 55.1 frames.

Faucher will make $1.8 million in 2026 after losing his arbitration hearing with the Marlins on Saturday, Mark Feinsand of MLB.com reports.

Faucher had filed for $2.05 million, but he'll receive the lower of the two figures after posting a 3.28 ERA and 1.28 WHIP across 60.1 innings in 2025. The 30-year-old collected 15 saves while serving as Miami's primary closer last season, but he'll likely be relegated to a setup role in 2026 while new addition Pete Fairbanks works the ninth inning.

Manager Dave Roberts said Saturday that it will take some time to build Graterol (shoulder) up this spring, Sonja Chen of MLB.com reports.

Graterol missed all of 2025 while recovering from a shoulder procedure he underwent in November 2024. He threw a bullpen session Friday, but Roberts noted that the 27-year-old's velocity "wasn't near where it's going to be." The team's plan to slow Graterol's rehab down could delay his Cactus League debut, and it's unclear if he'll be ready to go by Opening Day.

Miller has been limited to playing catch thus far during spring training and is ramping up slowly after he underwent labral repair surgery on both of his hips in October, Jason Beck of MLB.com reports.

Though he's present at big-league camp and is soaking up knowledge from veteran pitchers such as Tarik Skubal and Justin Verlander, Miller isn't expected to pitch in any Grapefruit League games while he works his way back from a pair of surgeries. Instead, the 24-year-old prospect is focusing on a throwing program and getting back to full health. Miller showed some promise in 2025 when healthy, posting a 1.80 ERA and striking out 21 batters across 20 total innings between Single-A Lakeland and Double-A Erie. He will likely begin 2026 at Double-A again and could move up to Triple-A Toledo at some point if he continues to impress.

The Diamondbacks placed Martinez (elbow) on the 60-day injured list Saturday.

The move will create space on Arizona's 40-man roster for Paul Sewald, who signed with the club on Thursday. Martinez underwent Tommy John surgery in June and is expected to return to the D-backs' bullpen near the end of August.

Assad arrived at spring training Thursday after a slight delay due to a visa issue, Jordan Bastian of MLB.com reports.

Assad was slightly delayed in his arrival from his native Mexico, but it doesn't seem that the issue will interrupt his spring routine at all. The 28-year-old has served as both a starter and a long reliever the past few seasons for the Cubs. Assad missed most of last year with an oblique injury and will look to turn in a fully healthy campaign in 2026. He looks destined for the bullpen with the Cubs adding Edward Cabrera to the rotation and Cade Horton emerging as a strong starting option last season.

Ballesteros has not arrived at spring training yet due to a visa issue, but manager Craig Counsell said he is "expected shortly," Sarah Barber of Sports Illustrated reports.

Ballesteros has yet to receive clearance to travel from his native Venezuela, but Counsell downplayed the issue and said he's not worried at this point about the delay. It's an important spring for the 22-year-old catching prospect, who debuted for the Cubs last season and posted an impressive .868 OPS across 20 games. Ballesteros is the favorite at this point to serve as the Cubs' top DH option in 2026, and he could mix in some behind the plate in relief of Carson Kelly and Miguel Amaya.

Imanaga is working on his pitch repertoire in spring training, including tweaking his sweeper and sinker grips and adding a cutter, Jordan Bastian of MLB.com reports.

Chicago pitching coach Tommy Hottovy said the goal is to help Imanaga throw his sweeper from his "natural arm slot." With the sinker, they want to find a grip that helps the pitcher maintain velocity. Imanaga is also working to reintroduce a cutter after not throwing the pitch last season. The 32-year-old primarily used his four-seam fastball and splitter in 2025, and after a strong start to the year that resembled his stellar 2024 rookie campaign, he stumbled down the stretch to finish the regular season with a 3.73 ERA. Imanaga will aim to get back on track with his revamped pitch mix, and he makes for an intriguing fantasy option with some bounce-back appeal.
