Clark's fielding, never his specialty, played a pivotal role in the 1985 World Series. Umpire Don Denkinger's notorious controversial call in Game 6 came from Clark's throw to Todd Worrell at first. Clark would later misplay a foul popup that, while not ruled an error, should have been caught. Darrell Porter later admitted that he called off Clark but hesitated at the last minute when he thought Clark had called for the catch, which Clark had not. This opened the door for the Kansas City Royals to score two runs in the bottom of the 9th to win Game 6, and go on to capture the World Series in Game 7 the following night.
