Replay for home run calls is relatively new. The Berkman Decision (which neither ne nor his team argued) was only the third in postseason history. A-Rod benefited from a replay review last Oct. 31 against the Phillies in the World Series. A non-home run call was overturned and ruled a home run.
Just nine days ago, a home run by Chase Utley of the Phillies was reviewed and upheld.
