Did the New York Yankees the New York Rangers and the Dallas Cowboys ever win games on the same day?

This has in fact happened.

On November 1st, 2009:

Rangers beat Bruins 1-0

Cowboys beat Seahawks 38-17

Yankees beat Phillies 7-4 to take a 3-1 lead in the World Series

This has, according to sources, not happened before (or at least in a long time.)
