Go began serving a 10-game suspension at Triple-A St. Paul on July 25 after he was ejected from his appearance against Columbus a day earlier when an illegal substance was found in his glove, Bobby Nightengale of The Minnesota Star Tribune reports.

The 28-year-old right-hander was making his debut for St. Paul after the Twins optioned him to the Triple-A affiliate. Go, who retains a spot on the Twins' 40-man roster, allowed four earned runs on eight hits and two walks while striking out five over four innings in four appearances for the big club prior to his demotion. He'll be eligible to return to action for St. Paul on Thursday.

Zeferjahn allowed two hits and struck out four without walking a batter over 1.2 scoreless innings to earn the save in Sunday's 3-0 win over the Brewers.

Zeferjahn came in during the eighth inning after Sam Bachman (arm) was lifted due to fatigue. While it wasn't quick and tidy from there, Zeferjahn threw 24 of 30 pitches for strikes and worked around a pair of singles to preserve the lead. He's given up three runs, nine hits, two walks and two hit batsmen while striking out 21 over his last 12.1 innings, adding two saves and three holds in that span. Zeferjahn is at a 3.66 ERA, 1.20 WHIP and 75:32 K:BB through 51.2 innings this season. He has held onto a high-leverage spot for most of the campaign, collecting four saves and nine holds for the worst team in the majors.

The Tigers released Guenther on Friday.

Guenther made nine appearances for the big club in 2025, but he's spent all of 2026 at Triple-A Toledo after losing his spot on the Tigers' 40-man roster over the winter. The 30-year-old lefty posted a 5.40 ERA and 1.73 WHIP across 16.2 innings over 12 appearances with Toledo before hitting the 7-day injured list May 6 due to an unspecified health concern.

Bachman is dealing with right arm fatigue, Jack Janes of TheSportingTribune.com reports.

Bachman entered Sunday's 3-0 win over Milwaukee in the top of the eighth inning, recording one out while walking a batter before he was removed from the contest. Bachman threw nine total pitches before his departure, and manager Kurt Suzuki explained after the game that the right-handed pitcher is dealing with some "dead arm." Bachman is expected to be further evaluated, and it's currently unclear if he'll need to undergo an MRI.

The Nationals acquired Bird and right-handers Yovanny Cruz, Ben Grable and Jack Cebert (undisclosed) from the Yankees on Sunday in exchange for first baseman Luis Garcia, Mark Feinsand of MLB.com reports. Washington optioned Bird to Triple-A Rochester.

Bird will be on the move from the second trade deadline in a row after being shipped from the Rockies to the Yankees last summer. Before the Yankees optioned him to Triple-A Scranton/Wilkes-Barre on July 19, Bird had struggled over 36 appearances with the Yankees, pitching to a 5.93 ERA and 1.55 WHIP with 31 strikeouts over 30.1 innings in 36 appearances. Though he'll start out his time in the Nationals organization at Triple-A, Bird might not have to wait long for a call-up to a Washington bullpen that's lacking in dependable arms.

Peguero (hamstring) threw a 15-pitch live bullpen session Friday at the Giants' facility in Arizona, MLB.com reports.

Peguero is scheduled to repeat the activity again Wednesday, and if all goes well, he could then start throwing live batting practice. The reliever has been on the shelf since June 1 due to a left hamstring strain and appears to be trending toward a late-August return from the injured list.

The Giants transferred Gage (elbow) from the 15-day injured list to the 60-day IL on Sunday.

After landing on the IL on July 4 due to a left flexor strain, Gage received a platelet-rich plasma injection July 11 and was scheduled to be re-evaluated in the second week of August, per MLB.com. Gage's move to the 60-day IL indicates that the Giants aren't counting on him being ready to rejoin the big-league bullpen until at least Sept. 2. The transaction also opens up a spot on the 40-man roster for infielder Buddy Kennedy, who was claimed off waivers from the Mariners on Sunday.

Cruz and three minor-league pitchers were traded to the Nationals from the Yankees in exchange for Luis Garcia on Sunday, Mark Feinsand of MLB.com reports.

Cruz will head to Washington after he posted a 1.69 ERA and 0.75 WHIP with six strikeouts over 5.1 innings in four appearances with the Yankees this season. The right-hander will likely slot right into the Nationals' major-league bullpen upon his arrival with the organization. Minor-league pitchers Jake Bird, Ben Grable and Jack Cebert will also head to Washington in the transaction.

The Mariners recalled Simpson from Triple-A Tacoma ahead of Sunday's game against the Twins.

Simpson has appeared in four games out of the Seattle bullpen this season, giving up three earned runs on four hits and two walks across three innings. He'll likely be in store for an abbreviated stay with the big club, as the Mariners will need to clear room on the 26-man active roster for the newly acquired Seranthony Dominguez prior to Tuesday's series opener with the Tigers.

The Tigers recalled Hanifee from Triple-A Toledo on Sunday.

The right-hander will fill the roster spot vacated by Tarik Skubal, whose trade to the Dodgers was made official Sunday. Hanifee has been a solid relief option for Detroit this season with a 3.98 ERA and 1.33 WHIP over 20.1 innings, though he's surrendered nine home runs and struck out just eight batters.
