Sanmartin will be sidelined for three months after being diagnosed Monday with a severe right hip flexor strain, Susan Slusser of the San Francisco Chronicle reports.

Sanmartin suffered the injury during a recent exhibition game and an MRI revealed a serious injury. The left-hander had been competing for a spot in the Giants bullpen after being claimed off waivers from the Reds back in November.

Miller (back) is scheduled to throw a live batting practice session Tuesday, Susan Slusser of the San Francisco Chronicle reports.

The live BP session will be the final hurdle that Miller needs to clear in his recovery from a back injury before making his Cactus League debut, perhaps as soon as later this week. Considering that Miller wasn't tasked with recording more than four outs in any of his 36 relief appearances for the Giants last season, he won't require much ramp-up time and should be ready to go for Opening Day.

Soriano (illness) will start Monday's Cactus League game against the Giants.

Soriano missed his last turn because he was battling an illness, but he's been cleared to return to action after more than a week of rest. The right-hander will be looking to get back on track after being knocked around for seven runs over 3.2 innings in his first two starts this spring.

Lopez (elbow) allowed three runs on three hits and a walk across two innings in Sunday's Cactus League win over the Dodgers. He struck out one.

Lopez returned to the mound after closing the 2025 season on the injured list with a left elbow strain and being slow-played to open spring. The right-hander was hit around over his two frames, surrendering a solo homer to Andy Pages in the first inning and back-to-back doubles to Nick Senzel and Ryan Ward in the second inning that each plated a run. Aside from the results, Lopez simply returning to action is an encouraging sign as he looks to be healthy for the regular season. After posting a 4.08 ERA, 1.27 WHIP and a 113:37 K:BB across 21 appearances (17 starts) and 92.2 innings last year, Lopez is a strong candidate to open the 2026 season in the rotation, though a number of arms -- including Luis Morales, Jack Perkins and J.T. Ginn -- are also vying for spots at the back end of the staff.

Topa gave up four earned runs on four hits, including a home run, with two strikeouts Sunday to increase his spring ERA to 30.38. He's given up nine earned runs in 2.2 innings.

Topa does have a 5:3 K:BB in 2.2 innings, so he's at least striking out batters. It's still early in the spring and Topa as a veteran may be focusing on some aspects of his arsenal. However, this isn't inspiring for his chances to earn saves in the unsettled Twins closer competition.

Hader (biceps) will throw a bullpen session Tuesday, Brian McTaggart of MLB.com reports.

Hader will take the mound for the first time since he developed left biceps inflammation prior to reporting to Astros camp. While he hasn't yet been officially ruled out for Opening Day, Hader is unlikely to avoid a stint on the injured list. Bryan Abreu appears to be in line to serve as the Astros' closer at the beginning of the season.

Nunez was optioned to the Orioles' minor-league camp Sunday, Roch Kubatko of MASNSports.com reports.

Nunez appeared in five games with Baltimore during spring training, tossing five scoreless innings while allowing three hits and striking out six batters over five innings. The right-handed pitcher will now likely open the season with Triple-A Norfolk, and he'll look to impress in an attempt to get a shot with the major-league roster this season.

De Los Santos (knee) is expected to complete one more bullpen session before facing hitters in live batting practice Friday, Brian McTaggart of MLB.com reports.

The upcoming live BP session will represent the final checkpoint De Los Santos will need to hit in his recovery from a right knee strain before gaining clearance to make his Grapefruit League debut. De Los Santos worked mainly in middle relief between stops with Atlanta and Houston last season, picking up six wins and six holds and submitting a 4.36 ERA, 1.29 WHIP and 62:24 K:BB across 66 innings.

The Rays optioned Cook to minor-league camp Sunday.

The 24-year-old was added to Tampa Bay's 40-man roster in November but was always a longshot to crack the Opening Day roster. Cook missed some time in 2025 due to injuries but pitched well for Double-A Montgomery when available, finishing with a 2.30 ERA, 0.86 WHIP and 18:3 K:BB over 15.2 innings.

Colorado optioned Peralta to Triple-A Albuquerque on Sunday, Patrick Lyons of JustBaseball.com reports.

The left-hander finished 2025 working in the majors but is set to open 2026 in the minor leagues. Peralta had a 9.47 ERA and 16:18 K:BB across 19 frames in the big leagues last year, and he wasn't much better at Triple-A with a 9.09 ERA.
