Ko Woo-seok (28, Minnesota Twins), who will wear his fourth uniform since moving to the United States, is finally realizing his dream of making his big league debut. He has seized a golden opportunity due to Minnesota's weak bullpen.
Minnesota acquired Ko Woo-seok from the Detroit Tigers in a cash trade on the 6th (Korean time).
Twins Daily reported on the 7th, "While this acquisition may not spark major headlines, it is significant for the Twins, who are continuing their fight for an American League wild card spot, as they have secured another promising pitcher." The outlet added, "Because Ko Woo-seok's contract includes a no-trade clause, the Twins were required to include him on the 40th-man roster. Fortunately, there was an open spot on the 40th-man roster, so no additional measures were necessary."
The media stated, "He recorded an ERA of 2.60 this season with a strikeout rate of 29.3%. He also allowed zero home runs. While these records reflect his ability to limit hits against batters (a high batting average against of 0.239), his fundamental skills remain attractive." The outlet continued, "His ability to record strikeouts and induce ground balls provides the Twins with another potential bullpen option. This is especially valuable given Minnesota's inconsistent performance from its bullpen."

It appears Ko Woo-seok is a perfect fit for Minnesota's weak bullpen. The media noted, "Aside from Yoendrys Gómez and Andrew Morris, there are almost no pitchers who have shown consistent performance in the bullpen during the first half of the season." They evaluated that "Minnesota's bullpen posted an ERA of 5.28, a strikeout rate of 19.9%, a walk rate of 11.5%, and a ground ball rate of 39.7%. All four metrics rank in the bottom 10 percent."
This acquisition is even more valuable given that Minnesota is a small-market team. The media remarked, "It is another attempt by the club's front office to create value without sacrificing future assets," highlighting Ko Woo-seok's performance as a closer during his time in the KBO League. They added, "They expect these strengths to translate against big league batters as well. The timing is also appropriate. With only a few weeks remaining until the trade deadline, the front office is not constrained by player acquisitions or releases. The club can reduce salary burdens and maintain its pool of prospects while making potential reinforcements."
The media predicted that Ko Woo-seok would join the team on the 8th and make his big league debut immediately.
Having served as one of Korea's top closers, Ko Woo-seok secured the saves champion title with 42 saves in 2022 and helped LG Twins win the championship the following year. He moved to the United States after being selected by San Diego in 2024 but was involved in a 1-for-4 trade with young prospects midway through the 2024 season, enduring two instances of outright assignment. Although he played for the Miami Marlins and Detroit Tigers, he never achieved his dream of promotion to the big leagues.
In particular, he appeared in 19 games over 27⅔ innings at Triple-A, recording 3 wins, 1 loss, 2 saves, 3 holds, an ERA of 2.60, a batting average against of 0.162, and a WHIP of 0.98, posting statistics befitting an elite pitcher. Despite never being called up even once, he has finally secured his opportunity. Although he received offers to return to Korea, the result is especially meaningful as it was achieved after steadfastly persevering.
