Go Woo-seok has been suspended for 10 games after a foreign substance was found on his glove in the U.S. minor leagues.
According to reports from Minnesota media outlets Pioneer Press and Star Tribune on July 27, the Major League Baseball (MLB) office confirmed Go's 10-game suspension.
Go was inspected by umpires before his relief appearance during a home game against the Columbus Clippers, a minor league affiliate of the Cleveland Guardians, on July 25.
MLB and minor league regulations strictly prohibit pitchers from applying sticky substances to their gloves to gain an advantage when throwing the ball.
Using substances like pine tar can increase a pitcher's spin rate, enhancing the effectiveness of fastballs and breaking balls.
As Go approached the mound, umpires inspected his glove and hands, discovering a foreign substance inside the glove. They called for additional umpires and instructed Go to leave the game, confiscating his glove.
Go accepted the suspension without contesting it, and the minor league umpires have sent his glove to the MLB office for a thorough investigation.
Since moving to the U.S. in 2024, Go has spent a considerable amount of time in the minor leagues. He was demoted after allowing three runs in one inning against Cleveland on July 21.
In four big league appearances, he recorded one hold with an earned run average of 9.00.
