De Los Santos was optioned to Triple-A Scranton/Wilkes-Barre on Thursday, Max Goodman of NJ.com reports.

De Los Santos was activated from the injured list Saturday and has made two scoreless appearances since. The Yankees made a flurry of additions to their bullpen at the trade deadline, costing De Los Santos his spot on the big-league roster.

Hamilton was optioned to Triple-A Scranton/Wilkes-Barre on Thursday, Max Goodman of NJ.com reports.

Hamilton had been fairly effective for the first three months of the season, but his ERA ballooned to 6.10 across 10.1 innings in July. He could contribute in the majors again in 2025, though he'll likely be limited to low leverage given New York's stacked bullpen.

Enns was traded from the Tigers to the Rays in exchange for cash considerations Thursday.

Enns was designated for assignment earlier in the day after the Tigers acquired Codi Heuer. However, he now looks likely to immediately contribute to Baltimore's bullpen. He's maintained a 5.60 ERA and 1.53 WHIP across 17.2 innings in the majors this season.

The Guardians claimed Hernandez off waivers from the Tigers on Thursday, Tim Stebbins of MLB.com reports.

Hernandez was pushed off the Tigers' 40-man roster last Thursday after surrendering 13 runs (12 earned) in just 10.2 innings. He'll now reclaim a 40-man roster spot upon moving to the Guardians organization, though he'll likely have to redeem himself in Triple-A before he gets another shot in the bigs.

Loaisiga earned the save in Thursday's 7-4 win over the Rays, allowing one hit and logging a strikeout in a scoreless ninth inning.

With both Devin Williams and Luke Weaver having pitched Wednesday, it was Loaisiga who got the call in the ninth inning Thursday to close out a three-run lead. The right-hander managed to work around a Matt Thaiss lead-off double to pick up his first save since 2022. Loaisiga has been solid of late, delivering six straight scoreless appearances (4.2 innings). However, he's unlikely to see many save chances going forward, as the Yankees added both David Bednar and Camilo Doval at the trade deadline to fortify the back end of their bullpen.

Doval was traded from the Giants to the Yankees on Thursday in exchange for Jesus Rodriguez, Parks Harber and Trystan Vrieling, Jack Curry of YES Network reports.

Doval had been the Giants' closer for the past couple months, but he hadn't recorded a save since July 11. Now that he joins a loaded Yankees bullpen, Doval will likely have to settle for opportunities in the seventh and eighth innings.

Maton was traded from the Cardinals to the Rangers on Thursday in exchange for Skylar Hales, Mason Molina and international bonus pool money, Katie Woo of The Athletic reports.

The Cardinals dealt all their high-leverage relievers, so Maton's brief time atop the closer depth chart in St. Louis comes to an end. Robert Garcia is the incumbent in Texas, and he has had a lot of recent success, so Maton should return to a setup role.

The Blue Jays acquired Varland and Ty France from the Twins on Thursday in exchange for Alan Roden and Kendry Rojas, Mitch Bannon of The Athletic reports.

Varland has worked as a full-time reliever this season for the first time in his professional career, and he's transitioned to the role flawlessly with a 2.02 ERA, 1.10 WHIP and 47:13 K:BB across 49 innings. The right-hander should be in the high-leverage mix for Toronto but isn't likely to be a consistent candidate for saves.

The Rays acquired Jax from the Twins on Thursday in exchange for Taj Bradley, Marc Topkin of the Tampa Bay Times reports.

Jax briefly appeared poised to step in as Minnesota's closer after Jhoan Duran was dealt on Wednesday, but the Twins instead fully committed to being deadline sellers. Jax had been operating has a setup man and is likely to fill the same role in Tampa Bay, though closer Pete Fairbanks' 5.79 ERA in his past nine outings could provide a path to saves.

The Padres traded Neighbors to the Orioles on Thursday as part of the package for Ramon Laureano and Ryan O'Hearn, Dennis Lin of The Athletic reports. The Orioles also received Brandon Butterworth, Victor Figueroa, Cobb Hightower, Boston Bateman and Tanner Smith in return.

Neighbors has flown up the Padres' farm system since being drafted last season, and he currently boasts a 3.13 ERA with a 1.04 WHIP and a 27:13 K:BB through 23 innings in Double-A. The 22-year-old righty will aim to continue his fast ascent through the minors with the Orioles, though his MLB debut will likely have to wait until next season.
