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 the suspension for Go Woo-seok.
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 while pitching.
Using substances like pine tar can increase the spin rate of the ball, enhancing the effectiveness of fastballs and breaking pitches.
As Go Woo-seok approached the mound, umpires inspected his glove and hands, discovering a foreign substance inside the glove. They called for additional umpires and ordered Go to leave the game, confiscating his glove.
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.
