**No 4-homer game has occurred in the 2026 MLB regular season through late September, with the maximum in any contest remaining at three.** Multiple players, including Lucas Spence (September 24), Alex Bregman (twice in August), Pete Crow-Armstrong, and Cal Raleigh, have reached three home runs in a game, but none have extended to four amid the season’s final days. Four-home-run performances are exceptionally rare in MLB history—only 21 instances across more than a century, with the most recent in 2025. The absence through roughly 160+ games per team reflects typical late-season dynamics: strong pitching staffs, bullpen usage, and matchup-specific factors that limit single-player outbursts, even as team home-run totals remain elevated in some contests. With the regular season nearly complete and playoffs imminent, the remaining schedule offers few additional opportunities for such an outlier event. Trader consensus prices this scarcity accordingly, treating a 4-homer game as a low-probability outcome absent a dramatic late surge.
