Jonathan Bowlan Earns High Marks in First Season with Philadelphia Phillies

Philadelphia Phillies reliever Jonathan Bowlan earned a B+ grade for his 2026 campaign after being acquired in a trade. Bowlan registered a 3.36 ERA, 3.37 FIP, 31.9 K%, and 6.6 BB% across 59 appearances (56.1 IP). Utilizing a high-velocity fastball and effective slider, Bowlan developed into one of manager Don Mattingly's most trusted high-leverage arms before late-season fatigue and an IL stint affected his workload.
