One of the most controversial plays of Rodriguez's career occurred late in Game 6 of the 2004 American League Championship Series. With one out and Derek Jeter on first base in the bottom of the eighth inning, Rodriguez hit a slow roller between the pitcher's mound and the first base line. Red Sox pitcher Bronson Arroyo fielded the ball and ran towards Rodriguez to apply a tag. As Arroyo reached towards him, Rodriguez swatted at his glove, knocking the ball loose. As the ball rolled away, Jeter scored all the way from first as Rodriguez took second on the play, which was initially ruled an error on Arroyo. However, the umpires quickly huddled, then ruled that Rodriguez was out for interference. Jeter was sent back to first base, and his run was nullified. The Yankees would then lose the ALCS to the eventual World Series champion Red Sox after leading the series 3 games to none.
