On July 7, 2001, Guerrero threw out Alberto Castillo in one of the most exalted throws in MLB history. After a base hit by Toronto, Castillo, then a baserunner on second base, saw a patent opportunity to reach home base and score a run, as the batter had hit the ball well into deep-right field. Guerrero caught the ball off a bounce and launched the ball all the way to his catcher, who received the throw, on the fly and squarely into his waiting mitt. Castillo was tagged out short of home plate. The throw's distance has been estimated to have been roughly three hundred feet, with its vertical arch peaking at merely twenty-one feet.
