As the 2025 MLB season progresses, the spotlight shines on several starting pitchers showcasing noteworthy changes. Edward Cabrera of the Miami Marlins has made significant adjustments, including a dramatic decrease in four-seam fastball usage. Instead, he is now leaning on breaking balls, particularly a newly refined slider and a revamped curveball that shows promise for whiffs. These changes may herald a breakout season if Cabrera can maintain control.

Ben Brown of the Chicago Cubs, despite a recent impressive performance against the Dodgers, struggles with consistency. His high walk rates and reliance on two pitches raise red flags for long-term success. Shane Smith from the White Sox is also navigating his own challenges. While he showcases effective velocity, his pitch distribution needs refinement to effectively compete against right-handed hitters. Finally, Yusei Kikuchi's transformation with the Angels has initially yielded disappointing results, with concerns surrounding his new arm slot and pitch command.
