Game: 1996 ALCS, Game 1
Match-up: Baltimore Orioles vs. New York Yankees
If we've learned anything from Steve Bartman or Jeffrey Maier, it's that fan interference can be profound enough to warrant a biographical Wikipedia page. And while Bartman's transgression led him to go into hiding, Maier's become a pop culture phenomenon. The then-pre teen is famous for grabbing a Derek Jeter fly out away from Orioles right fielder Tony Tarasco. By bringing the ball into the front row seats at Yankee Stadium, Maier contributed to an egregious missed call by Umpire Richie Garcia and effectually tied the game for the Yankees. New York would go on to win the game in extra innings and, later, the World Series.
