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.

The Diamondbacks reassigned Rashi to minor-league camp Sunday, Alex Weiner of ArizonaSports.com reports.

Rashi reached the majors for the first time with Arizona in 2025, appearing in 10 games and logging a 4.41 ERA, 1.47 WHIP and 22:8 K:BB over 16.1 innings. After being non-tendered in November, Rashi re-signed with Arizona on a minor-league deal shortly thereafter. He wasn't able to crack the Diamondbacks bullpen coming out of spring training, but Rashi could be in the mix for a promotion to the big club if he pitches well with Reno early in the upcoming season.

The Rockies optioned Herrera to Triple-A Albuquerque on Sunday, Patrick Lyons of JustBaseball.com reports.

The 21-year-old lefty was added to Colorado's 40-man roster in November but was never a likely bet to make the Opening Day roster. Herrera spent most of last season with Double-A Hartford, where he had a 3.69 ERA, 1.30 WHIP and 70:19 K:BB across 46.1 innings.

The Diamondbacks optioned Holman to Triple-A Reno on Sunday, Alex Weiner of ArizonaSports.com reports.

Holman tossed a scoreless inning in his lone Cactus League appearance to date, but having a pair of minor-league options remaining might have hurt his cause for breaking camp as a member of the Diamondbacks' Opening Day bullpen. With the Athletics last season, the 25-year-old righty made 22 appearances (two starts) at the big-league level, logging a 5.09 ERA, 1.52 WHIP and 17:9 K:BB in 23 innings.

The Diamondbacks optioned Burgos to Triple-A Reno on Sunday, Alex Weiner of ArizonaSports.com reports.

Burgos was one of 15 players dismissed from big-league camp in the Diamondbacks' latest round of roster cuts. The 26-year-old righty was unable to secure a spot in Arizona's Opening Day bullpen after yielding four earned runs on six hits and two walks over 2.1 innings in the Cactus League.

Garcia (illness) struck out three batters over two perfect innings in his last two Cactus League appearances Wednesday and Saturday.

During his second appearance of the spring Feb. 28, Garcia was lifted early after falling ill, but he needed just a few days to move past the issue. The 25-year-old lefty has allowed just two total baserunners over three innings this spring, putting him in good shape to break camp as a member of the Diamondbacks' Opening Day bullpen.

Ort (elbow) struck out one batter in a perfect inning of relief Thursday in the Angels' 16-11 loss to the Athletics in Cactus League play.

While he was a member of the Astros last season, Ort didn't make any appearances after Sept. 4 due to right elbow inflammation. The right-hander was briefly a member of the Yankees' 40-man roster over the offseason before being claimed off waivers in late January, and New York outrighted him just over a week later. Ort is attending big-league spring training as a non-roster invitee and will look to string together a few more quality relief appearances in the Cactus League to make his case for a spot in the Angels' Opening Day bullpen.

The Mariners optioned Loutos to Triple-A Tacoma on Sunday.

Scooped up off waivers from the Nationals earlier in the offseason, Loutos will begin his time in the Mariners organization at the Triple-A level after he was unable to secure a spot in the Opening Day bullpen. The right-hander took himself out of consideration after yielding seven runs (six earned) on seven hits over three innings in four appearances during Cactus League play.
