Mets are stunned on Castillo’s error

Alex Rodriguez slammed his bat and then threw it. The first Subway Series game at new Yankee Stadium was over.

And then it wasn’t.

Second baseman Luis Castillo dropped A-Rod’s popup with two out in the ninth inning as two runs scored, and the Yankees escaped with a 9-8 victory over the Mets on Friday night.

David Wright had put the Mets ahead 8-7 with an eighth-inning double off Mariano Rivera (1-2), and Francisco Rodriguez (1-1) appeared to get his 17th save on the popup by A-Rod.

But the ball popped out of Castillo’s glove in short right field, and the Yankees ran onto the field as Derek Jeter scored from second and Mark Teixeira from first.
