The relationship between pitching performance and variability was analyzed using multiple regression analysis.<h4>Results</h4>MLB players exhibited smaller ball release point variability compared to MiLB players. The analysis showed that pitching performance was strongly related to ball release point variability, especially in the horizontal direction on the coronal plane. Horizontal ball release point variability was most strongly related to strikeout abiliFrontiers in sports and active living1447665https://www.ebi.ac.uk/biostudies/studies/S-EPMC11608975biostudies-literatureRelationship between ball release point variability and pitching performance in major league baseball.PMC11608975Wakamiya KOgawa YLiu ZNagamoto HYamaguchi RKumai TMaemichi TKobayashi YOkunuki TfalseRelationship between ball release point variability and pitching performance in major league baseball.<h4>Introduction</h4>This study examined the relationship between ball release points and pitching performance among professional baseball pitchers, with a focus on variability.<h4>Methods</h4>We used open-source data to compare ball release point variability between Major League Baseball (MLB) and Minor League Baseball (MiLB) players.
