Sandlin (elbow) is listed among the Angels' available relievers for Sunday's Cactus League game against the Rockies, Jeff Fletcher of The Orange County Register reports.

The Angels haven't confirmed that Sandlin will pitch Sunday, but his inclusion on the lineup card nonetheless indicates that he's fully ramped back up after he was eased along during the first few weeks of spring training while he recovered from an offseason arthroscopic procedure on his right elbow. Since he's attending camp as a non-roster invitee, Sandlin likely won't have sufficient time to stake a claim to a spot in the Angels' Opening Day bullpen, but he could put himself in the mix for an early call-up if he pitches effectively at Triple-A Salt Lake to begin the season.

The Rangers outrighted Diaz to Triple-A Round Rock on Sunday.

After signing a one-year deal with Texas in December, Diaz entered spring training with a chance to stake his claim to the closer job in an unsettled bullpen. The right-hander's lack of command during spring training ultimately resulted in him not only falling short of a high-leverage role, but a spot on the 40-man roster. He'll remain in the Texas organization after drawing no interest on the waiver wire, having yielded eight earned runs on three hits and four walks over 1.2 innings in the Cactus League.

The Mariners reassigned Rucker to minor-league camp Sunday.

After sitting out the entire 2025 season, Rucker signed a minor-league deal with the Mariners in January and had been attending camp as a non-roster invitee. He's expected to open the upcoming campaign at Triple-A Tacoma and will serve as bullpen depth. The 31-year-old previously saw big-league action with the Cubs in 2021-23, logging a 4.96 ERA and 1.39 WHIP over 123.1 innings across 96 regular-season relief appearances.

Brieske (ribcage) worked around a walk to toss a scoreless inning of relief in Friday's 7-5 loss to the Pirates in Grapefruit League play.

After he was briefly shut down with right ribcage tightness, Brieske returned to the mound Friday for his third appearance of the spring and his first since March 2. Manager A.J. Hinch was satisfied with how the right-hander looked Friday, noting that he hit 96 miles per hour with his fastball and displayed "pretty good" stuff, per Chris McCosky of The Detroit News. Brieske looks poised to break camp with the Tigers and is likely to fill a middle-relief role.

Astros manager Joe Espada said that De Los Santos (knee) is slated to pitch in a game Tuesday, Brian McTaggart of MLB.com reports.

Espada didn't specify whether De Los Santos will be pitching in the Astros' Grapefruit League game against the Pirates that day or in a minor-league game, but either way, it will be the first action of the spring for the 30-year-old righty. De Los Santos has been slowed by a right knee strain suffered at the beginning of camp, but he's since resumed facing hitters and is slated to take part in pitcher's fielding practice Sunday. He shouldn't require much of a ramp-up period and appears on track for Opening Day.

Lopez allowed no hits and a walk across four scoreless innings in Saturday's Cactus League win over the Royals. He struck out seven.

After allowing a leadoff walk to Nick Loftin, Lopez proceeded to retire every other batter he faced, striking out over half of them. He was brought along slowly to open the spring after he closed the 2025 season on the injured list due to an elbow strain, but the southpaw looked fully healthy Saturday. Lopez is expected to open 2026 with a spot in the big-league rotation, as the 28-year-old looks to build on a season in which he posted a 4.08 ERA, 1.27 WHIP and a 113:37 K:BB across 21 appearances (17 starts) and 92.2 innings.

The Astros reassigned Willingham to minor-league camp Sunday, Brian McTaggart of MLB.com reports.

The 27-year-old right-hander made 19 appearances in the big leagues for Washington in 2023-24, but he spent all of 2025 in the minors as a member of the Atlanta organization, logging a 5.17 ERA in 55.2 innings across stops with four different affiliates. After being cut from the Astros' big-league camp, Willingham will likely open the 2026 campaign at Triple-A Sugar Land.

The Astros reassigned Cosgrove to minor-league camp Sunday, Brian McTaggart of MLB.com reports.

Cosgrove is expected to serve as organizational bullpen depth at Triple-A Sugar Land to begin the season after he was unable to secure a spot in the Astros' Opening Day bullpen. The 29-year-old lefty joined Houston on a minor-league deal over the winter after he spent time in the Padres and Cubs organizations in 2025 and made just two relief appearances at the big-league level.

The Mariners optioned Ortiz to Triple-A Tacoma on Saturday.

Ortiz spent the entire 2025 season in the minors before he was traded by the Dodgers to the Mariners in mid-November. The 26-year-old southpaw will not be on Seattle's Opening Day roster, but he could make his major-league debut in 2026 if the Mariners need additional depth out of the bullpen. In the minors last season, Ortiz posted a 2.73 ERA, 1.30 WHIP and 72:33 K:BB across 59.1 innings.

White Sox manager Will Venable told reporters Saturday that Newcomb will work out of the bullpen for the 2026 season, Kyle Williams of the Chicago Sun-Times reports.

Newcomb has operated as a starter for most of his major-league career, but he found success while primarily working out of the bullpen with the Red Sox and Athletics in 2025, posting a 2.73 ERA, 1.35 WHIP and 91:31 K:BB across 92.1 innings. He inked a one-year deal with the White Sox in December and was competing for a rotation spot early in camp. Although he won't open the season as a starter, Newcomb could see some spot starts to help give the White Sox's rotation extra rest.
