The Red Sox optioned Booser to Triple-A Worcester on Wednesday, Pete Abraham of The Boston Globe reports.

The 32-year-old has a 2.00 ERA and 4:3 K:BB over nine innings since being recalled by Boston on July 12, but he'll be the odd man out of the bullpen as Chris Martin (elbow) returns from the injured list. Booser has been a reliable bullpen piece for the Red Sox this season with a 2.77 ERA and 1.13 WHIP in 38 outings, so he should be back in the big leagues before too long.

The Red Sox reinstated Martin (elbow) from the 15-day injured list Wednesday, Chris Cotillo of MassLive.com reports.

The right-hander looked good during his bullpen sessions over the past week and will rejoin the Red Sox without a minor-league rehab assignment. Martin has a 3.42 ERA, 1.03 WHIP and 29:2 K:BB across 26.1 innings this season and should return to a setup role now that he's healthy.

Brash, who underwent season-ending elbow surgery May 8, has been with the Mariners during their current homestand and is set to begin playing catch in Arizona next week, Daniel Kramer of MLB.com reports.

Brash has been taking a brief respite from rehabilitation activities and reconnecting with the big-league staff and teammates, but he'll be heading to Arizona for what will be a closely monitored start to his throwing program. Brash has already been engaged in one-handed pitch-and-catch plyometric exercises on a trampoline, and he reports being very pleased with the pace of the early stages of his recovery and the way he's felt while carrying it out. Due to the fact Brash had an internal brace procedure instead of a full Tommy John surgery, his recovery isn't expected to take much more than 12 months, leaving him with a chance to be back in action by June 2025.

The Orioles recalled Baker from Triple-A Norfolk on Wednesday.

Baker has made 14 appearances out of Baltimore's bullpen this season, allowing nine runs with a 14:5 K:BB across 17.2 innings. He will be utilized in middle relief.

The Orioles placed Webb on the 15-day injured list Wednesday with right elbow inflammation.

It's not clear when Webb's elbow began bothering him, but his last appearance came Saturday, when he went 1.2 scoreless innings against the Guardians. Bryan Baker was called up from Triple-A Norfolk to take Webb's spot in the bullpen and on the 26-man active roster.

The Orioles recalled Akin from Triple-A Norfolk on Wednesday.

He'll make his return to the big club as a replacement on the 26-man active roster for right-hander Grayson Rodriguez (shoulder), who was placed on the 15-day injured list. Before he was sent back to Triple-A on Aug. 1, Akin had struck out 12 while allowing one earned run on four hits and two walks over 10 innings across his last nine relief appearances, so his demotion likely had more to do with the fact that he had a minor-league option remaining rather than the Orioles being dissatisfied with his performance.

The Rays optioned Kuhnel to Triple-A Durham on Wednesday.

Kuhnel tossed two scoreless innings out of the bullpen in Tuesday's 4-3 loss to the Cardinals and was unlikely to be available for another day or two, so he was an easy choice for the Rays to move off the active roster to clear room for right-hander Drew Rasmussen (elbow), who was reinstated from the 60-day injured list in a corresponding move. The 29-year-old right-hander will head back to Durham after making a pair of two-inning appearances in relief following his July 30 promotion.

Jimenez (oblique) fired a scoreless inning in Triple-A Las Vegas' win over Sacramento on Tuesday, allowing a hit and recording two strikeouts.

Jimenez got through his one frame on a tidy 12 pitches, eight of which he located for strikes. The right-hander may only need to make a couple more rehab appearances before being deemed ready for activation, especially if they go as smoothly as Tuesday's did.

The Athletics designated Reyes for assignment Wednesday, Martin Gallegos of MLB.com reports.

Reyes was up with the big club for a week, allowing three runs (two earned) over four innings covering three relief appearances. The 31-year-old is likely to clear waivers and stick around in the organization as bullpen depth at Triple-A Las Vegas.

The Athletics activated Miller (finger) from the 15-day injured list Wednesday, Martin Gallegos of MLB.com reports.

Miller is back after a minimum 15-day absence as a result of a fractured left pinkie finger. He did not make a rehab appearance but completed a live batting practice session Monday to convince the Athletics he was ready to go. Miller should immediately regain his closer role for Oakland.
