The Twins are taking a low-cost shot on Woo-Suk Go, landing the right-hander from the Tigers in exchange for cash considerations, according to MLive Media Group’s Evan Woodbery. Detroit had not carried Go on its 40-man roster, and Dan Hayes of The Athletic reported that Go’s assignment clause means Minnesota will have to add him to its roster.
Go had been with the Tigers on a non-roster deal since December, but he never got the spring training invite and spent most of the season at Triple-A instead. The numbers there were strong enough to turn heads: a 2.60 ERA across 27 2/3 innings, a 29.1% strikeout rate, and no home runs allowed. His .239 average on balls in play points to some good fortune, but the overall performance was enough to push him back into the conversation for a big league job.
Detroit apparently wasn’t willing to open a roster spot for him, so the Twins get the benefit instead. Minnesota has an open place on its 40-man roster, which means no corresponding move is required to bring Go aboard. He is set to join the club on Tuesday, per Hayes.
The timing makes sense for a Twins bullpen that has been one of the league’s weakest units in 2026. Andrew Morris has been the lone qualified reliever in the group with an ERA under 4.00, and he has posted a 17.1% K-BB rate with a 3.04 xERA in 40 innings. Beyond him, the relief corps has struggled badly, carrying a 5.28 ERA, a 19.9% strikeout rate, an 11.5% walk rate, and a 39.7% ground ball rate, all of which rank in the bottom 10 in the majors.
Go’s calling card is still the same one that made him interesting in the first place: strikeouts and ground balls. His control has been uneven since he came over from Korea in 2024, but Minnesota is betting the stuff plays.
The Twins are 44-47 after beating the Yankees today and sit tied with the Astros, two games out of an AL Wild Card spot. That leaves the door open for this to be more than just a flyer, though the club still has time to decide whether it’s buying or selling before the deadline.
For now, Go looks like a bullpen lottery ticket with a real path to innings. He will be making his big league debut once he gets into a game.
If the Twins stay in the race, he may not get much runway. If they fade by the deadline, he could be around longer in August and September.
There is also a bit of roster flexibility baked into the move. Go was outrighted by the Marlins in 2024, which means he would be able to reject another outright assignment if Minnesota were to designate him in the future.

Tigers Finally Have A Flaherty Trade Prospect Worth Watching Again
When the Tigers sent Jack Flaherty to the Dodgers in 2024, the return looked like the kind of deal that would need time to sort itself out. Trey Sweeney has not given Detroit much to celebrate so far, but Thayron Liranzo is starting to change the tone around that trade package, and his progress has put him back on the radar as one of the more interesting young names in the system.
Liranzos path has not been smooth, with injuries and personal tragedy helping drag down a season that pushed him off multiple top-100 lists. Even so, the catcher has shown enough improvement to earn another look on a bigger stage, and his renewed attention gives the Tigers at least one reason to keep watching the Flaherty deal with fresh eyes.

Tigers Make Sudden Coaching Change Amid Growing Baserunning Scrutiny
The Tigers made a notable coaching adjustment in the middle of the season, with A.J. Hinch saying third base coach Joey Cora has left the organization and Billy Boyer is stepping into the role right away. Boyer had been working in the clubs system as quality control coach and minor league infield coordinator, so this is a familiar internal move rather than a hire from outside the building.
The timing adds weight to the change, coming as Detroits baserunning has drawn more attention and the club continues to look for cleaner execution on the margins. Cora had also been handling infield instruction, and Boyer is expected to take on those responsibilities as well, giving the Tigers a broader shift in how that part of the staff is organized moving forward.

Baseball America Just Delivered A Brutal Reality Check On Tigers Prospects
Baseball Americas midseason farm system rankings delivered a sharp reminder of how quickly a prospect pipeline can lose its shine. Detroit slid to No. 22, an 18-spot drop from where it stood before the season, with the decline tied to a mix of injuries and the natural churn that comes when top talent moves up the ladder.
The Tigers have already watched Kevin McGonigle and Hao-Yu Lee graduate from the system, and the depth behind them has been thinned by a wave of injuries across the organization. Even with Max Clark and Bryce Rainer still among Baseball Americas top-100 prospects, the ranking underscores how much pressure is now on the rest of the farm to rebound and restore some of the luster that made Detroits system so highly regarded not long ago.
