Twins Bullpen Addition Just Hit A Sudden And Bizarre Setback

Woo-Suk Go faces unexpected challenges with a suspension following his ejection for a foreign substance, leaving the Twins to navigate the reliever's immediate future.

Woo-Suk Go’s first night with Triple-A St. Paul ended before it ever really began.

The Twins’ recent trade pickup was supposed to work out of the Saints bullpen on Friday after Minnesota optioned the right-hander to Triple-A last week. Instead, he was tossed in the seventh inning before throwing a pitch after an alleged foreign substance was found on his glove.

Go is now in the middle of a mandatory 10-game suspension.

Major and Minor League Baseball umpires started regularly checking pitchers for foreign substances between innings and after pitching changes during the 2021 season, and Go’s ejection dropped him right into that enforcement.

Minnesota acquired Go from the Detroit Tigers for cash on July 5. Because of a clause in his contract, the Twins had to put him on their 26-man roster right away after the deal. He still has options, though, which gave the club the ability to send him to the minors.

The 27-year-old had already gotten a taste of the majors with Minnesota this year. In four relief appearances, he gave up four earned runs on eight hits, including two home runs, along with two walks and five strikeouts over four innings before being demoted.

Go’s move to St. Paul came as the corresponding transaction for right-hander Jack Anderson, who the Twins claimed off waivers from the Boston Red Sox earlier this month. Minnesota had just sent Anderson back to the Saints to make room for Cole Sands, who was reinstated from the injured list.

The suspension is a setback, but it doesn’t change the bigger picture around Go’s season. Because he still has options, the Twins can keep moving him between Triple-A and the big-league roster the rest of the year, and he could be the next arm up when Minnesota needs help.

Even with the 10-game ban, the missed time for a reliever should amount to roughly 2-4 games, and he can keep his arm moving with bullpen sessions while he serves it.

Go has been sharp in the minors. Across 27 appearances between Triple-A and Double-A this year, he has put up a 1.96 ERA, a 0.82 WHIP and a 34.0% strikeout rate.

Before reaching the Twins organization, Go pitched in the KBO from 2017-23. He signed a two-year, $4.5 million deal with the San Diego Padres in January 2024, then was traded to the Miami Marlins as part of the Luis Arraez deal on May 4, 2024. The Marlins released him on June 17, 2025, the Tigers signed him to a minor-league deal about a week later, and Detroit brought him back on another minor-league contract this past offseason before sending him to Minnesota on July 5.

Twins Rotation Suddenly Has A New Injury Problem

The Twins rotation took another hit this week, with Joe Ryan working through arm fatigue and getting back on the mound after a bullpen session, a reassuring sign for a staff that has been trying to hold together its depth for much of the season. Ryans status matters because he has been one of the anchors at the top of the rotation, and even a short scare around him can ripple through a group that has already been asked to absorb plenty of innings.

Minnesota is also dealing with more than one setback behind him, which only sharpens the focus on how much pitching help the club can realistically count on down the stretch. With the front office already having to think about coverage and contingency plans, the latest round of injuries has made the rotation picture feel a lot thinner than it did not long ago.

Twins Shortstop Decision Feels Closer Than Ever After Kreidler Slide

Ryan Kreidlers bat has been trending the wrong way for more than a month, but the Twins have kept finding reasons to lean on his glove. The utility man gave them a useful early-season boost and still offers the kind of defensive versatility that matters on a roster that is always shifting, especially at shortstop where reliability can be hard to come by.

The timing, though, is getting harder to ignore. Minnesota has been reshuffling infield pieces around him, and the organization now has another option moving closer to the picture in Kaelen Culpepper. Kreidlers recent surge was enough to remind everyone what he can do when the ball starts finding gaps, but the bigger question for the Twins is whether that brief lift can change the direction of a job that suddenly feels much less settled.

Rays May Be Pushing Twins Toward A Deadline Decision Fans Dread

The Twins have spent enough of the summer trying to stay afloat that the trade deadline is starting to look less like a chance to add and more like a moment to make hard choices. Tampa Bays heavy scouting of Minnesota is only sharpening that possibility, because the Rays rarely sit around without a plan, and the Twins know they have players with enough offensive value and team control to draw real interest.

Ryan Jeffers and Trevor Larnach fit the kind of profile that can tempt a front office into listening, especially with Minnesota carrying enough internal depth to absorb some of the blow if it decides to move in that direction. Larnachs bat has been one of the more reliable parts of the lineup, while Jeffers brings the sort of production that can matter to contenders, which is why this conversation feels less hypothetical by the day and more like the kind of deadline call fans would rather not see answered.
