In 2004, Albert Pujols was considered one of the best baseball hitters in the world, leading the Major Leagues the previous year with a .359 batting average. Jennie Finch was considered the world’s best softball pitcher, leading the U.S. to a Gold Medal in the Olympics by striking out more than one hitter per inning and giving up 0 runs. So when Finch challenged Pujols to a matchup, it was billed as a classic showdown of men vs. women. But that was just on the surface. Deep down, this matchup also provided the perfect experiment to test the limits of a human’s reaction time – and how our brains make it possible to surpass them.
