Santos (lat) is set to throw another live batting practice Friday in Seattle and could begin a rehab assignment shortly thereafter, MLB.com reports.

The right-hander put together a very encouraging live BP on Saturday in Miami before that day's game against the Marlins, using his sinker/slider combo with great effectiveness and impressive velocity against Ryan Bliss and Tyler Locklear in a 10-pitch session. If Santos encounters similar success Friday, it appears he'll be ticketed for what should be a fairly lengthy rehab assignment, given he's been sidelined since spring training.

Daniel will be recalled from Triple-A Salt Lake to start Thursday's game against the Tigers, Jeff Fletcher of The Orange County Register reports.

Other than a one-day stay with the Halos in mid-May in which he didn't make an appearance, Daniel has spent the entire season at Salt Lake, posting an ugly 5.33 ERA but a more promising 82:25 K:BB across 76 innings covering 14 starts. The 27-year-old right-hander appeared in three games out of the Angels bullpen in 2023, allowing three runs with a 9:9 K:BB over 12.1 frames. With Patrick Sandoval (elbow) out for the season and Jose Soriano (abdomen) still on the injured list, Daniel could get a chance to take multiple turns through the rotation.

The Yankees transferred Effross's (back) rehab assignment from Single-A Tampa to Triple-A Scranton/Wilkes-Barre on Wednesday.

Effross turned in a pair of clean rehab outings for Tampa, covering three shutout innings while striking out four. He'll likely be in store for a more extended stay at Scranton/Wilkes-Barre that could extend the full length of his 30-day rehab window, which began June 19. The right-hander missed the entire 2023 season while recovering from October 2022 Tommy John surgery and has been on the Yankees' injured list for the entirety of the current season while he works his way back from December back surgery.

The Rangers transferred Winn (shoulder) from the 15-day injured list to the 60-day IL on Wednesday.

Winn was placed on the 15-day IL earlier this week with what was referred to as right shoulder discomfort, but the Rangers are now classifying the injury as a sprained shoulder capsule. The expectation is that he will be sidelined for eight weeks, per Shawn McFarland of The Dallas Morning News.

Muller (shoulder) fired a scoreless inning in his rehab outing with Triple-A Las Vegas on Tuesday, allowing one hit and recording a strikeout.

Muller kicked off his rehab assignment in solid fashion, successfully working around a single and getting through his one frame on 10 pitches. The left-hander is due to make multiple appearances for the Aviators before activation is considered, although he may not need more than a couple of more outings considering he won't need to build up much as a result of his relief role.

The Tigers optioned Lucas to Triple-A Toledo on Wednesday.

Lucas' stay with the big club lasted just one day, and he went unused out of the bullpen in Tuesday's 4-1 win over the Phillies. He'll be replaced on the 26-man active roster by right-hander Keider Montero, who was called up from Toledo to serve as a bulk reliever in Wednesday's series finale versus Philadelphia.

Holton will serve as the Tigers' opening pitcher in Wednesday's game versus the Phillies, Evan Woodbery of MLive.com reports.

With left-handed sluggers Kyle Schwarber and Bryce Harper in the top three of the batting order, the Phillies are targets for southpaw openers. Holton will be followed by Keider Montero, who will be called up from Triple-A Toledo and will be deployed as a bulk reliever.

Hendriks (elbow) will throw a bullpen session Wednesday, Jen McCaffrey of The Athletic reports.

Red Sox pitching coach Andrew Bailey said Hendriks has been throwing "half-mound" sessions, but Wednesday's activity marks the reliever's first session throwing on the top of the mound since undergoing Tommy John elbow surgery last August. If Wednesday's workout goes well, a normal progression would have Hendriks throwing two bullpen sessions per week before ramping up to face hitters.

Hader allowed a solo home run and a walk with three strikeouts during Tuesday's 5-2 win over the Rockies.

Hader stepped into the game for the ninth inning despite not being eligible for the save and gave up his first home run since June 9 to Michael Toglia. After a shaky start to 2024, Hader owns a 2.25 ERA with 30 strikeouts and eight saves over his last 19 appearances. He's also walking batters at his lowest clip since 2019, with 2.4 BB/9 in 2024.

Spence (4-4) took the loss Tuesday, allowing six runs on eight hits and a walk across 5.1 innings against the Angels. He struck out six.

Spence surrendered his most runs in an outing this season Tuesday, with five of those runs coming in the fourth inning. The rookie right-hander allowed the first four batters he faced in the fourth to reach safely before Mickey Moniak cleared the bases with a grand slam. While Spence has been a bit inconsistent as a starter, he owns a 4.40 ERA in starts along with a 34:9 K:BB over 43.0 innings. He's projected for a rematch against the Angels early next week.
