On the final play of the June 12, 2009 Subway Series, Alex Rodriguez looked like he hit a pop up to end the game. Instead, Mets second baseman Luis Castillo dropped the ball and Derek Jeter who was at second scored as did Mark Teixeira from first.
Arod had just arrived at first when he saw Castillo drop the ball. He ROUNDED first base which could have cost the Yankees a run. He went back to first after first base coach Mick Kelleher started screaming and was pointing to first with both hands.
With two out in the 9th inning, had Arod been tagged out rounding first before Teixeira touched home, the inning would have ended at that point and the game would have been tied. Teixeira's run would not have counted.
Arod had nothing to gain by heading to second. The winning run was ahead of him. Once he touches first, he is irrelevant! He should have ran to first and stayed there. Luckily for him, he wasn't tagged out and all ended well, for the Yankees.
