Former Lotte Giants left-hander Ko Hyo-jun has broken a long silence regarding the turbulent internal dynamics of the club during the 2019 season, revealing a sharp conflict between the team’s field management and front office leadership. In a candid interview, the 43-year-old veteran pitcher detailed how a power struggle between then-manager Heo Moon-ho and General Manager Song Mingyu influenced player assignments and ultimately impacted his own free agency negotiations.
Ko, who spent the majority of his career protecting the Lotte mound, spoke on the YouTube program “Kim Gura’s Baseball Stalking,” a popular platform for unfiltered KBO insights. He described an environment where the chain of command was blurred, leading to friction that rippled through the roster. “I don’t think they were really suited for each other,” Ko said of the relationship between Song and Heo, noting that the General Manager’s active involvement in on-field decisions undermined the manager’s authority.
The friction came to a head during Ko’s own free agency negotiations following the 2019 season. Despite recording the first double-digit holds of his professional career that year, Ko found himself in a precarious position when leadership changes altered the team’s atmosphere. He recalled being suddenly removed from high-leverage situations as the club shifted focus toward developing younger players, a move he attributed to the changing guard in the front office.
A Disputed Free Agency Process
The most startling revelation concerned the terms of his contract renewal. Ko described a negotiation process marked by rigidity and ultimatums. According to the pitcher, General Manager Song Mingyu issued a strict 48-hour deadline for acceptance of the initial offer, warning that the value would decrease if the window closed.

“CEO Son has taken office and is negotiating the FA, and he notified the agent: ‘If you do not sign this amount within 48 hours, the amount will be reduced,'” Ko recounted. The initial offer stood at 100 million won per year with a 20 million won option, terms Ko felt were insufficient for a veteran free agent. When the deadline passed without a signature, the offer was indeed lowered.
Ko signed a one-year contract in March for 90 million won. “It was an amount that could not be called FA,” he admitted, expressing the damage the process inflicted on his pride. “My pride was badly damaged, but I had no choice but to accept it.”

Managerial Authority and Club Culture
When pressed by host Kim Gura on who was at fault in the organizational clash, Ko sided with the field manager. “Personally, it’s director Heo Moon Ho,” he stated. “What I felt while playing baseball was that the coach should be in complete control of the game. I have no doubt that it would have worked out if you had supported the director.”
Ko’s comments highlight a recurring debate in the Korea Baseball Organization regarding the balance of power between General Managers and field managers. While the American model often empowers the front office with data-driven roster construction, Ko argued that in-game authority must remain with the skipper to maintain clubhouse cohesion.
Beyond the specific conflict with Song, Ko offered a broader critique of the team’s culture during what fans often refer to as the club’s “Dark Ages.” He noted a disconnect between player performance and accountability, observing that popularity among fans sometimes shielded players from consequences even when their performance dipped. “As some young players become popular among fans, their attitude does not change even if they end up in the second group,” he observed, adding that this dynamic persisted from his initial tenure in 2002 through his return in 2018.
New Chapter in Ulsan
Despite the contentious end to his time in Busan, Ko Hyo-jun has found a new home in the independent leagues. He recently announced his signing with the Ulsan Weil Civic Club, expressing gratitude for the opportunity to extend his playing career. “I am grateful to the club for giving me the opportunity to challenge. I will repay you with fine grade,” Ko said.
Early results suggest the veteran still has command on the mound. In the current Futures League season, Ko has posted a 0.00 ERA over two games, demonstrating that his experience remains a valuable asset even as he transitions to a new chapter in his professional life.

As the KBO continues to evolve its front office structures, Ko’s testimony serves as a case study on the human cost of organizational misalignment. For now, the veteran pitcher is focused on the mound in Ulsan, looking to close out his career on his own terms.
