Answer Capsule

WHIP = (BB + H) / IP. Lower is better. 0.90 elite, 1.00 great, 1.20 average, 1.30 MLB average. Pedro Martinez 2000: 0.737 WHIP. Addie Joss career: 0.968.

Key Takeaways

  • WHIP measures baserunners per inning. Fewer is better.
  • Below 1.00 is elite; MLB average is around 1.30.
  • BR/9 = WHIP × 9 (baserunners per 9 innings).

ERA Correlation

WHIP and ERA correlate; fewer baserunners usually mean fewer runs.
