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.

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

Vrieling has a 4.50 ERA, 1.52 WHIP and 42:18 K:BB in 46 innings across 12 appearances at Double-A. The 24-year-old righty has a good curveball and cutter and may fit better in the bullpen long term.

The Brewers acquired Miller (forearm) and left-hander Jordan Montgomery (elbow) from the Diamondbacks on Thursday in exchange for a player to be named late, Robert Murray of FanSided.com reports.

Miller has been on the shelf since July 7 with a strained right forearm, but after turning in a 1.98 ERA and 0.96 WHIP in 36.1 innings with Arizona, he'll most likely take on a high-leverage role in Milwaukee's bullpen once healthy. However, after notching 10 saves for Arizona prior to getting hurt, Miller is unlikely to be in line for many ninth-inning chances in Milwaukee while Trevor Megill has performed as one of the top closers in baseball this season. Miller recently resumed throwing bullpen sessions and should soon face hitters again before likely heading out on a brief minor-league rehab assignment prior to being activated from the 15-day injured list.

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.

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

A pure reliever, Hales has had flashes of looking like a future late-inning arm, but he has struggled to prevent runs this year in the upper minors. The 23-year-old righty has a 7.64 ERA and 3.88 xFIP in 33 innings, primarily at Double-A, so he has been pretty unlucky while logging a 40:14 K:BB and five saves.

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.
