What happened: If Jacob Misiorowski reaches ERA-title qualification without that figure rising, it would become the lowest opponent OPS on record. His latest start produced 12 strikeouts, one hit and one run over five innings.
Why it matters: Qualification separates a dominant partial-season rate from an official single-season record. His 1.58 ERA also leads MLB, placing the pursuit inside an ERA-title campaign.
By the numbers: Opponent OPS: .450. Innings needed: 42. Latest start: 5 IP, 1 H, 1 ER, 0 BB, 12 K.
What to watch: The rate and innings total will move together with each start. Workload management over the final two months will determine whether he reaches qualification.
