MLB perfect games remain exceptionally rare, with just 24 recorded across more than 150 years of play and none since Domingo Germán’s in 2023. The feat demands one starter retire all 27 opposing batters without a hit, walk, hit-by-pitch, or error while completing the game, a sequence made harder by modern bullpen usage, pitch-count restrictions, and defensive variability. Entering late September 2026 with limited regular-season games remaining, traders assign overwhelming probability to no occurrence, consistent with historical frequency of roughly one every several seasons. Still, a dominant starter facing a weak lineup on a favorable night with strong defensive support could produce one before the schedule concludes.
