Kyung Heon-ho (49), the SSG Landers pitching coach who coached Ko Woo-suk (28, Triple A under the Detroit Tigers) for a long time with the LG Twins, revealed the hidden story. It is a hot topic as he revealed an episode of Ko Woo-seok, who purposely showed off his stubbornness by throwing as many as 15 breaking balls in response to media criticism that he does not throw breaking balls.

Coach Kyung Heon-ho mentioned Ko Woo-seok by appearing with MC Kim Gu-ra, NC Dinos pitching coach Seo Jae-eung, and commentator Kim Sun-woo in a video released by YouTube channel "Stocking" on the 6th. Coach Ko Woo-seok and Kyung Heon-ho have been together at LG for a long time.

When Kim Gu-ra asked if there was a player with strong stubbornness and personality among the players who coached in the past, coach Kyung Heon-ho recalled Ko Woo-seok. Then, Kim Gu-ra said, "I have to come (from the United States) by now. "I don't think he's listening to others because he's not coming to Korea yet," he said.

Coach Kyung, who laughed off Kim Gu-ra's joke, said, "It was a time when Ko Woo-seok was making good saves. He kept saying something in the media or broadcasts that he didn't throw breaking balls. It was such a situation, but one day, he threw 15 breaking balls in a row in the game. Even when I went up to the mound and asked, 'What are you doing now, are you kidding me?' he said, 'Okay,' and kept throwing breaking balls. "I felt like I was sending a message saying, 'I know how to throw a breaking ball,' and 'Don't say anything,'" he recalled.

Coach Kyung Heon-ho then added, "Fortunately, I didn't ruin the game. (Ko Woo-seok) is a very stubborn and very thoughtful player."

As coach Kyung Heon-ho and Kim Gu-ra pointed out, Ko Woo-seok's recent moves are very honest. He is showing his will to make his Major League debut. Ko Woo-seok, who crossed to the San Diego Padres through the posting system ahead of the 2024 season, is aiming to take the mound in the Major League for the third year ahead of the 2026 season.

After being traded from San Diego to the Miami Marlins for the previous two years, he suffered an absurd finger injury during spring camp in the 2025 season. Ko Woo-seok, who was eventually notified of his release in June last year, continued his dream by signing a minor contract with Detroit, but he never made a call-up. Ko Woo-seok has played only minor leagues for two years, recording 76 games (three starts) with 6 wins, 4 losses, 6 saves and an ERA of 5.61. Attention is also focusing on whether Ko Woo-suk's stubbornness, who will mark his third season in the U.S. in 2026, can come true as a dream.
