What happened: The longest game in professional baseball history stretched to 33 innings and lasted more than eight hours before being suspended without a decision. When play resumed at a later date, it took just a single inning to settle the outcome.

Why it matters: The marathon endures as one of the sport's great oddities, a reminder that baseball has no clock and a single game can spill across days. It remains the benchmark by which every long, extra-inning slog is measured.

What to watch: Expect the record to keep resurfacing each time a modern extra-inning game tests the limits of endurance.
