The Red Sox will designate Burdi for assignment Monday, Chris Cotillo of MassLive.com reports.

The transaction will free up a spot on the 40-man roster for the addition of left-hander Jovani Moran, who will be called up from Triple-A Worcester. Burdi has allowed two runs with a 4:3 K:BB over three innings at Worcester since returning from a hip injury. The righty reliever has pitched well this season when healthy, so he could receive interest via trade or waivers.

Alexander is expected to pitch in bulk relief behind opening pitcher Elvis Peguero in Monday's game against the Tigers, Jack Ankony of SI.com reports.

Alexander made a 3.1-inning start versus the Phillies on July 30, but his last two appearances have come out of the Chicago bullpen. In his most recent outing last Wednesday against the Mariners, Alexander shined in long relief behind starter Jonathan Cannon, striking out five batters while allowing just two baserunners over 4.1 scoreless frames and 67 pitches. With Cannon having since been demoted to Triple-A Charlotte, Alexander will essentially be taking his spot in the rotation Monday, as Peguero is expected to work just one or two innings before Alexander likely steps in and covers multiple frames out of the bullpen.

Brash picked up the save Sunday against the Rays, striking out one batter during a perfect ninth inning.

Brash took the mound in the ninth inning for a save opportunity as regular closer Andres Munoz got some rest after pitching three times in the last four days. It was Brash's second save in three games, and his third save of the campaign. The 27-year-old reliever has been outstanding in 2025, boasting a 1.16 ERA and a 35:12 K:BB in 31 innings pitched.

Newcomb pitched a scoreless inning, allowing one hit and a walk in Sunday's 3-2 win over the Orioles.

Newcomb extended his scoreless outings streak to seven straight appearances, and he's surrendered four hits and three walks while striking out 12 batters over nine innings during that stretch. The left-hander has been vaulted into a late-inning role with the A's, helping to fill the void left by Mason Miller, who was dealt to the Padres at the trade deadline. Newcomb now owns a 3.08 ERA and 1.43 WHIP with 78 punchouts over 36 appearances, including five starts, with the Red Sox and Athletics in 2025. He remains in the mix for high-leverage appearances with Michael Kelly and Elvis Alvarado, both of whom are right-handed, setting Newcomb up for matchup-based chances against left-handed batters.

Alvarado (1-0) pitched 1.2 scoreless innings, walking two batters and striking out two on his way to a win in Sunday's 3-2 victory over the Orioles.

Alvarado has been thrust into a prominent late-inning role following the departure of Mason Miller. He made the most of his opportunity Sunday, securing the first win of his young career. The right-hander has compiled a 3.04 ERA and 1.27 WHIP with 29 strikeouts over 19 appearances this season, and he's competing with Michael Kelly and Sean Newcomb for high-leverage opportunities moving forward in 2025.

Fluharty struck out one without allowing a baserunner over two-thirds of an inning to earn the save in Sunday's 5-4 win over the Dodgers.

Fluharty was stuck into one of the most fearsome situations after an unusually ineffective performance by Jeff Hoffman, who walked five batters Sunday. Fluharty inherited the bases loaded with one out, and he got Shohei Ohtani to strike out before inducing a grounder from Mookie Betts that was enough to end the game. Fluharty is now at a 5.15 ERA, 1.21 WHIP and 45:18 K:BB through 43.2 innings while collecting a save and four holds. He's mostly served in a low-leverage role this year -- he was called upon for this save chance only because he was one of two relievers left in the bullpen after the Blue Jays had to empty the tank due to Eric Lauer's poor start.

Hoffman (7-4) walked five batters without allowing a hit or recording a strikeout over two-thirds of an inning, taking a blown save and picking up the win Sunday versus the Dodgers.

Hoffman allowed an inherited runner to score the tying run after being brought in with two outs in the eighth inning. Ernie Clement restored the lead for the Blue Jays with a solo home run in the ninth, and Hoffman stayed in the game but struggled again. He may have been rusty after not pitching since Aug. 3, ultimately throwing just 10 of 33 pitches for strikes, but Mason Fluharty was able to work out of the jam to make the lead stick. Hoffman is now 26-for-31 on converting saves this season while posting an uninspiring 4.50 ERA along with a 1.13 WHIP and 64:16 K:BB over 48 innings. He doesn't appear to be at risk of losing the closing job as long as Sunday's poor outing is an isolated incident.

Akin (3-2) took the loss and a blown save in Sunday's 3-2 defeat to the A's. He allowed two runs on two hits and a walk while striking out two in the ninth inning.

Akin had converted his previous two save chances, allowing just one earned run over four innings in the absence of Felix Bautista (shoulder). Overall, the southpaw Akin sports a 3.56 ERA with a 1.47 WHIP and 43:23 K:BB across 43 innings. Despite the hiccup Sunday, Akin should remain Baltimore's primary ninth-inning option for the time being.

Thornton underwent season-ending surgery Monday to repair a torn left Achilles tendon and is expected to face a recovery timeline of 6-to-8 months, Daniel Kramer of MLB.com reports.

Thornton suffered the Achilles injury during a July 30 relief appearance and finished the 2025 season with a 4.68 ERA, 1.30 WHIP and 32:14 K:BB over 42.1 innings. Given the timeline laid out by Seattle, Thornton's availability for the start of spring training will likely be affected, and the injury could prompt the Mariners to non-tender him this winter as he heads into his final season of arbitration in 2026.

Peguero will serve as the White Sox's opening pitcher for Monday's game against the Tigers, Jack Ankony of SI.com reports.

After being claimed off waivers from the Brewers on Aug. 3, Peguero was recalled from Triple-A Charlotte on Sunday and will make his White Sox debut Monday in what will be his first MLB start. The right-hander will likely be limited to just one or two innings before turning the ball over to lefty Tyler Alexander, who is expected to pitch in bulk relief.
