As the MLB season nears its midpoint, several prominent hitters are struggling, and their difficulties may be linked to the quality of opposing pitchers they have faced. Hitters like Manny Machado (third baseman for the San Diego Padres) and Matt Chapman (third baseman for the San Francisco Giants) are encountering some of the highest average fastball velocities of their careers, which can adversely affect their performance. For instance, Machado has faced elite pitchers such as Shohei Ohtani and Jacob Misiorowski, which has contributed to his lower slugging percentage despite his underlying metrics remaining solid. Similarly, Chapman is dealing with increased fastball velocity and a flat swing that limits his ability to generate lift on the ball. Other players like Salvador Perez (catcher for the Kansas City Royals) are also showing signs of decline, with concerns about bat speed as they age. Additionally, Pete Alonso (first baseman for the Baltimore Orioles) faces a challenging division where he regularly encounters top-tier pitching. The overall trend indicates that hitters are struggling significantly against high-quality pitching, which is reflected in their performance statistics.
