Twins designate Woo-Suk Go for assignment after Triple-A struggles

The Twins designated right-hander Woo-Suk Go for assignment, the club announced, clearing a 40-man roster spot for outfielder Walker Jenkins. The move closes a brief chapter for Go in Minnesota, one that began with a July trade and included a four-inning major league debut but ended with a Triple-A line that made the roster math untenable.

What happened

Go came off the 40-man roster in a corresponding move after the Twins selected Jenkins' contract. The club also optioned outfielder Alan Roden to Triple-A St. Paul to open an active roster spot for Jenkins, per the announcement.

Go, 28, began the year with the Tigers on a minor league contract, MLB Trade Rumors reported. He triggered an assignment clause in that deal in July and was sent to the Twins. With Minnesota, he made his major league debut, allowing four earned runs in four innings. He was optioned to the minors after that appearance and has been at Triple-A St. Paul since.

Why it matters

The designation gives the Twins seven days to trade Go, release him, or place him on outright waivers. If he clears waivers, the club can outright him to the minors or release him. If another organization claims him, he moves to that team's 40-man roster.

For Minnesota, the move is a straightforward roster squeeze. Jenkins, a top prospect, required a 40-man spot, and Go's recent performance made him the logical candidate to come off. The Twins brought Go over in July presumably because of his Triple-A results with the Tigers' affiliate, but his time in St. Paul did not replicate that success.

The numbers

Before the trade, Go posted a 2.60 earned run average across 27 2/3 innings for Triple-A Toledo, per MLB Trade Rumors. He struck out 29.1% of batters faced, walked 10%, and generated ground balls at a 44.8% rate.

With Triple-A St. Paul, he allowed 13 earned runs in 9 1/3 innings. Control became a significant issue, the report noted, though specific walk figures for his time in Minnesota's system were not disclosed.

His major league debut spanned four innings and four earned runs. The Twins optioned him shortly after.

Where the club stands

The Twins are 68-74, third in the AL Central and six games behind the division lead. They sit seventh in the American League Wild Card race, 3.5 games behind the cut line. Minnesota has won one game in a row and opens a three-game series against the White Sox on Friday at Target Field, with Dean Kremer scheduled to face Luis Castillo.

Bailey Ober is slated to pitch Saturday against Erick Fedde, and Zebby Matthews is lined up for Sunday opposite Jordan Hicks.

The Jenkins promotion is the headline roster move. Go's departure creates the 40-man space, and Roden's option to St. Paul opens the active spot. The Twins are 28 games into August with a month of baseball remaining, and the Wild Card math is steep but not yet impossible.

What we don't know yet

Whether another club will claim Go on waivers is the immediate question. His Triple-A work with Toledo suggests he can miss bats and limit walks when things are working, but the St. Paul sample is recent and poor. A team with 40-man flexibility and a belief in the earlier performance might take a chance.

If Go clears waivers, the Twins can outright him to the minors, though he would have the right to refuse the assignment and elect free agency as a player with prior major league service. The club could also release him outright.

The seven-day window runs through early September, when rosters expand to 28 active players. That timing may influence how the Twins handle the designation if Go is not claimed.

What to watch

The waiver period will resolve Go's immediate future. If he is claimed, he moves to another organization's 40-man roster and could surface in a major league bullpen before the season ends. If he clears, his decision to accept or refuse an outright assignment will determine whether he remains in the Twins' system or tests the free-agent market.

For Minnesota, the focus shifts to Jenkins and the final month of the season. The Twins are 3.5 games out of the Wild Card with roughly 20 games to play, a deficit that requires near-perfect baseball and help from the teams ahead of them. The Jenkins call-up suggests the front office is evaluating its future pieces even as the playoff window narrows.

Go's departure is a reminder of how quickly minor league success can evaporate when the environment changes. His 2.60 ERA in Toledo looked like the foundation for a useful bullpen arm. His St. Paul line—13 earned runs in 9 1/3 innings—looked like a different pitcher entirely. The Twins made the trade in July with the Toledo version in mind. They made the designation in August with the St. Paul version in the books.

The White Sox series begins Friday night. The Twins will send Kremer to the mound against Castillo, a matchup that pairs two pitchers with different trajectories this season. Minnesota needs to win games in bunches to stay in the Wild Card conversation, and the schedule offers no favors. The Jenkins promotion adds a new name to the outfield mix. The Go designation removes a pitcher who never found his footing in the organization.

The 40-man roster now has an open spot, though that will not last long. The Twins have decisions to make as September approaches, and the roster churn that defines the final month of a season on the playoff bubble is already underway. Go's brief tenure in Minnesota is over. The waiver wire will decide what comes next.
