Texas Rangers closer, Joe Nathan, is a New York Giants fan. Fellow reliever, Mike Adams, is a Dallas Cowboys fan. Put the two together, along with the Giants and Cowboys playing each other for the season opener,  and you've got a good old fashioned bet among teammates.

Nathan paid off the bet by wearing a full Tony Romo Cowboys uniform - including pads, helmet and cleats. He wore the uniform during Tuesday's (9/11) batting practice before the game against Cleveland. He also made a stop by the stands to sign autographs for some lucky fans.

Mike Adams also made a similar bet with Rangers General Manager, Jon Daniels, who had to wear a Cowboys cap during media interviews.
