During the 2012 NL Wild Card game between the St. Louis Cardinals and the Atlanta Braves, a fly ball was hit by Atlanta. St. Louis let the ball drop due to miscommunication, but an umpire called "infield fly rule."

Do the umpires have grounds to call "infield fly rule" when a fly ball will clearly land that deep in the outfield? What are the rules regarding the "infield fly rule?"
