The Astros acquired Ferguson from the Yankees on Tuesday in exchange for right-hander Kelly Austin, Jack Curry of YES Network reports.

Ferguson will provide the Astros with additional bullpen depth after appearing in 42 games with the Yankees this season. The 27-year-old logged a 5.13 ERA, a 1.50 WHIP and 10 holds across 33.1 innings for New York. He's not expected to see much high-leverage work in Houston.

The Angels acquired Baumann from the Giants on Tuesday in exchange for cash, Robert Murray of FanSided.com reports.

San Francisco designated Baumann for assignment Saturday, but he'll regain a 40-man roster spot with a new organization. He's out of minor-league options and thus will need to be added to the Angels' 26-man active roster. The right-hander reliever holds a 4.84 ERA and 1.44 WHIP over 35.1 innings across 36 appearances with the Giants, Mariners and Orioles.

The Red Sox designated Walter (shoulder) for assignment Tuesday, Gabrielle Starr of the Boston Herald reports.

The move frees up a spot on the 40-man roster for trade-deadline acquisition Lucas Sims. Walter has been sidelined all season with a shoulder strain, an injury he suffered in early March. Assuming he clears waivers, Walter will remain on Triple-A Worcester's 60-day injured list.

The Red Sox acquired Sims from the Reds on Tuesday in exchange for right-hander Ovis Portes, Robert Murray of FanSided.com reports.

Sims has posted a 3.57 ERA and 40:20 K:BB over 35.1 innings in 2024 as a member of the Reds bullpen. The pending free agent boasts a career 27.5 percent strikeout rate but also an 11.9 percent walk rate. He'll slot in as a setup man for Boston in front of closer Kenley Jansen.

The Yankees acquired Leiter from the Cubs on Tuesday in exchange for infielder Benjamin Cowles (undisclosed) and right-hander Jack Neely, Jeff Passan of ESPN.com reports.

Leiter recorded 13 holds with a 4.21 ERA, 1.10 WHIP and 53:13 K:BB over 36.1 innings for the Cubs, and he's been lights out of late with seven straight scoreless appearances. The right-hander is unlikely to see save chances in New York but should work as part of the bridge to closer Clay Holmes.

The Twins are expected to call up Dobnak from Triple-A St. Paul on Tuesday, Phil Miller and Bobby Nightengale of the Minneapolis Star-Tribune report.

Dobnak hasn't pitched in the majors since 2021, having had to remake himself into a slider and changeup pitcher after permanent ligament damage in his right middle finger left him unable to throw his sinker. He's been on fire lately at St. Paul, collecting a 1.70 ERA and 42:16 K:BB over 42.1 innings covering his last eight starts. It's not clear what role the Twins have planned for Dobnak, but he could provide innings protection behind their starter for Tuesday's game against the Mets, David Festa.

Brebbia (0-6) allowed three earned runs on one hit and one walk while recording one out to take the loss Monday against the Royals.

Brebbia is the presumed closer in Chicago after Michael Kopech was dealt to the Dodgers on Monday. However, things didn't go as planned when he entered the game with a runner on first and a one-run lead, as he allowed the first two batters he faced to reach base -- one was hit by a pitch -- before serving up a game-winning grand slam to Bobby Witt. Brebbia has now allowed eight earned runs across his last five appearances -- spanning four innings -- so even if he does pick up rare save chances, he's likely to provide very poor ratios.

The Mariners outrighted Devenski off the 40-man roster and assigned him to Triple-A Tacoma on Tuesday.

The 33-year-old has been with Tacoma since signing a major-league contract with Seattle in early July, and he pitched well in six outings with two earned runs allowed and a 5:0 K:BB over 5.1 innings. Devenski is likely losing his place on the 40-man roster to make room for trade-acquisition Justin Turner.

Holton will serve as the Tigers' opening pitcher in Tuesday's contest versus the Guardians, Chris McCosky of The Detroit News reports.

Holton will draw his fourth opener assignment of the season, with three having come within the past week. In his previous three starts, Holton has allowed one run with a 5:2 K:BB over 5.1 innings. The Tigers haven't announced their plans for once Holton exits the contest, but Joey Wentz is available on three days' rest and could serve as a bulk reliever after covering at least two innings in four of his past five appearances.

Stratton (3-3) allowed one run on two hits and struck out one over 1.2 innings to earn the win over the White Sox on Monday.

Stratton got out of Angel Zerpa's jam in the sixth inning but went on to give up an Andrew Vaughn solo home run in the seventh. The Royals then rallied from behind with a six-run eighth, giving Stratton his first win since April 23. The right-hander is at a 4.60 ERA, 1.35 WHIP and 38:27 K:BB with four saves and five holds over 43 innings this season. He's played an important role in the bullpen, but Stratton's mediocre numbers make him a shaky fantasy option.
