Pitcher finds success with a sub-100 km/h curveball

Samsung Lions pitcher Choi Ji-gwang is experiencing a resurgence in his performance, largely attributed to his effective use of a slow curveball. This unique pitch, often traveling at speeds below 100 km/h, has been catching opposing batters by surprise, leading to successful outcomes for Choi. Choi, 28, has been utilizing this 'slow curve' to his advantage, creating confusion for hitters accustomed to faster pitches. The effectiveness of this strategy was evident in his recent outing on June 23rd against LG at Jamsil Stadium, where he threw a curveball clocked at 96 km/h to Moon Bo-gyeong on the first pitch. This newfound success comes after Choi underwent elbow surgery in September 2024. The recovery process and subsequent adaptation of his pitching repertoire, particularly the incorporation of this slower, deceptive curveball, seem to be paying dividends for the pitcher. While the article notes Choi's possession of a similar curveball, he expressed surprise at how effective his current version has become. The strategy appears to be a key element in his ability to compete and find success on the mound.
