Prior to beating the Yankees on the Citi Field diamond last night, the Mets gauged their Bronx rivals at the ticket window.

According to a person with knowledge of the situation, the Mets charged Yankees family members $250 for last night’s Subway Series game.

The fact the Mets charged the Braves $80 per seat Friday, Saturday and Sunday angered the Yankees, who host the Mets tomorrow and Thursday night.

Not only did family members of the Yankees have to watch their team lose, 2-1, they paid much more to do it.
