0.737 was Pedro Martínez's WHIP in 2000, a remarkable statistic indicating his exceptional control over opposing batters. WHIP, or Walks and Hits per Inning Pitched, measures the number of walks and hits allowed by a pitcher per inning. Martínez's low WHIP demonstrates his ability to limit baserunners, making him one of the most dominant pitchers in Major League Baseball history.
