Go Woo-suk career transition from MLB to KBO

Pitcher Go Woo-suk elected free agency in late August 2026 after clearing waivers following his designation for assignment by the Minnesota Twins. His time with the Twins included a brief Major League Baseball debut followed by a stint with the Triple-A St. Paul Saints, which was marked by command struggles and an eight-game suspension for using a foreign substance.

Following his pursuit of Major League Baseball, which included stints with the San Diego Padres, Miami Marlins, and Detroit Tigers, Go returned to the LG Twins in South Korea on a one-year contract. While his return provides bullpen depth, KBO regulations regarding postseason eligibility mean he will be ineligible to participate in the playoffs, as players must be registered by July 31.

On September 4, 2026, Go successfully completed his KBO return by recording a save during a 4-3 victory against the Samsung Lions at Jamsil Baseball Stadium. Pitching one scoreless inning with a maximum fastball velocity of 154 km/h, Go secured his 140th career save, making him the 14th player in league history to reach that milestone. The win extended the LG Twins’ winning streak to five games, narrowing the gap with second-place Samsung to 3.5 games.
