Casey Mize Earns 'F' Grade After Disastrous Stint with Padres

Casey Mize struggled severely after being traded from the Detroit Tigers to the San Diego Padres, earning an 'F' grade for his 2026 performance. Over 10 starts (44.2 innings), Mize posted a 7.46 ERA, 1.68 WHIP, and allowed a .306 opponent batting average while managing just two quality starts. Reports indicated he pitched through a groin injury and also twisted an ankle during a start. Acquired alongside prospect Gage Workman, Mize is now set to hit free agency.
