Kyle Leahy, the St. Louis Cardinals’ pitcher, has transitioned from a mixed-role reliever to a starter in 2026, achieving 2.4 fWAR and ranking 40th among MLB starters. His performance has shown improvement over the season, particularly from June onward, with a notable drop in HardHit% and an effective pitch mix, including a strong ground ball rate and low walk rate. However, challenges remain, especially in navigating lineups the third time through. Concerns about his increased workload and potential injury risks persist as he continues to develop at age 29.
