Martín Pérez spun seven innings of one-hit ball, but Chicago’s bullpen flopped late, permitting five runs and blowing a lead as Kansas City surged to a 5-4 win. Colson Montgomery supplied a homer, Kyle Teel added an RBI knock, and the South Siders’ lineup fought back after Luis Robert Jr. left with hamstring soreness. Fantasy takeaways: Pérez remains a trusted start, while the White Sox bullpen continues to inject risk into any late-inning win potential. KC’s late rally boosts Witt Jr.’s fantasy profile, though the drama underscored volatility in both bullpens.
