KIA Tigers’ left-handed ace Lee Eui-ri is showing signs of a significant turnaround after completing a training stint in Japan. Once struggling with control and a high pitch count, Lee has found a new approach, attributing his improved performance to a shift in mindset and focused biomechanical analysis during his time at the NEXT BASE ATHLETES LAB in Japan.
From Struggles to Stability: Lee Eui-ri’s Mid-Season Transformation
The first half of the season was a difficult period for Lee Eui-ri. In his initial 10 starts, he recorded a mere 1-6 win-loss record with a 9.42 ERA over 35.1 innings. A primary concern was his control, evidenced by a high rate of 8.41 walks per nine innings and 21.1 pitches per inning. Despite possessing a powerful fastball that often exceeded 150 km/h, Lee was unable to translate this velocity into consistent success, leading to frustration.
Recognizing the challenges, KIA Tigers’ management offered Lee the opportunity to train in Japan in June. Facing a point of no return, Lee accepted the proposal. “I believe the team and the general manager considered me a lot when they suggested the training in Japan,” Lee stated. “It was definitely a time when I had to show something, and I think it was a good decision.”
The Japanese Training: A Focus on Biomechanics and Mindset
The training at NEXT BASE ATHLETES LAB focused on identifying the root causes of Lee’s issues and setting a direction for change. “The biomechanics analysis helped check things like the flow of power and how I distribute force,” Lee explained. “I don’t think my worries are entirely gone, but things have improved since I was in Japan. Instead of trying to do more, I wanted to hold onto this feeling of improvement and build upon it.” He added, “Originally, I might have tried to do something extra, but by being content and letting go a bit, things seem to be working out better.”
Upon his return to the first team at the start of the second half of the season, Lee demonstrated a revitalized presence on the mound. In his first three appearances of the latter half, he secured one win with a 3.2 innings pitched, allowing no runs. A key difference noted was the absence of walks, a stark contrast to his earlier struggles. Except for one hit by pitch against SSG Landers on July 19th, his recent pitching has been remarkably clean.
A New Approach to Pitching
Lee expressed cautious optimism about his current form. “It’s still early in the second half, so it’s premature to be too satisfied. However, I feel good about getting off to a solid start,” he said. “Before, I felt like the ball didn’t have much power behind it, and I didn’t feel like I was using my own strength effectively, relying too much on specific pitches or counts. Now, even though I’m in the bullpen and sometimes rely on specific pitches, I feel like I’m using my strength well, and that’s the most significant improvement.”
KIA manager Lee Beom-ho elaborated on the difference in Lee’s approach. “When he was a starter, he had to conserve his energy and be selective with his pitches to ensure he could go deep into the game. Sometimes, throwing too hard could lead to the ball being hit hard,” the manager explained. “Now, as a reliever, his primary job is to get batters out. He throws without holding back, which seems to lead to a clearer mental state. When starting, he had to think about pitching for a long time, worrying about things like the catcher’s glove positioning. As a reliever, he warms up and goes straight in, which simplifies his mental approach.”
Lee Eui-ri echoed this sentiment, stating, “When the ball feels like it has more power, I find myself focusing more on the situation rather than getting lost in my own mechanics. That’s why I think I’m seeing better results.”
Adapting to the Bullpen Role
Although Lee’s career has primarily been as a starting pitcher since his debut with KIA in 2021, he is adapting well to the bullpen role. “The difference from starting is that sometimes you have to prepare suddenly, and the game situation changes constantly with runners on base or when we’re batting,” he noted. “It’s challenging but also exciting. Multi-inning relief appearances aren’t significantly harder than starting, though maintaining focus for extended periods when moving to the next inning can be tough. Mentally, though, I feel more at ease.”
Manager Lee Beom-ho plans to continue developing Lee in the bullpen, with the intention of deploying him as a starter should an opening arise. Lee is eager to contribute to the team’s success in any capacity. “My biggest hope is to help the team,” he said. “Whether it’s pitching long relief in a losing game or coming in when needed in a winning situation, I’m ready. If I continue to prepare this way and get opportunities, I believe I can return to being a starter for multiple innings.” He added, “Our current starters are doing well, so by focusing on my role now, I think we increase our chances of winning.”
Looking Ahead: Consistency and Contribution
Despite facing his most significant challenge in his sixth professional season, Lee Eui-ri remains determined to persevere. “Every year is the same. I used to think a lot about which pitch to throw, what kind of pitch to use against a specific batter, and how to win the count,” he reflected. “But when my control faltered, things didn’t work out. During my time in the Futures League before returning to the first team, I gained some breathing room and stopped overthinking. Instead of struggling to find ways to face batters due to a lack of control, I’m now focusing on how to face them first. This simpler approach feels much more comfortable.”
Lee also expressed a desire to perform well for pitching coach Lee Dong-geol, who has been instrumental in his comeback. “Coach Lee always says encouraging things to me,” Lee said with a smile. “He keeps telling me to be a closer, but I believe closing is for someone else. For now, I’ll do as I’m told, and if I do well, I believe I can move to any position.”
