Instant replay in MLB actually had been used once before in the 1999 season during a Florida Marlins home game at Pro Player Stadium. This was the first instance in which instant replay was utilized in Major League Baseball. While playing the St. Louis Cardinals, Cliff Floyd hit a ball off the top of the left-field scoreboard. Originally ruled a double and then ruled a home run, NL Umpire Frank Pulli reverted the call back to a double after consulting a TV monitor in the Marlins' dugout. The Cardinals won the game, 5-2, and the Marlins protested the use of the TV monitor. The National League Office declared that the umpires erred in using instant replay, and the American League Office concurred that instant replay was not to be used in the future. However, the Marlins' protest was denied on the grounds that it was a judgment call rather than a rules violation as such, and the play stood. MLB did not use instant replay again for almost a decade.
