The WALL STREET JOURNAL conducted a study in baseball “clutchness” and came to a surprising verdict as the sport’s greatest hit: Tony Womack’s one-out, ninth-inning double off Mariano Rivera in 2001, which improved the Diamondbacks’ chances of winning the World Series from 39% to 83%, the largest differential a single at-bat has ever made in terms of a team’s likelihood to win it all.

Bill Mazeroski’s more famous 1960 W.S. walk-off homer rates slightly lower, because the Pirates already has a 65% chance of winning the title when Maz led off the bottom of the ninth.
