Jeffrey Maier (born November 15, 1983) is an American baseball fan who received media attention for an incident in which he was involved as a 12-year-old at a baseball game. During Game 1 of the 1996 American League Championship Series between the New York Yankees and the Baltimore Orioles, Maier deflected a batted ball, hit by Derek Jeter, into the Yankee Stadium stands for what umpires ruled to be a home run, rather than fan interference. His action altered the course of Game 1, as the resulting home run allowed the Yankees to tie the score. They won the game and won the series four games to one en route to winning the World Series.
