From Gene Wojciechowski on espn.com:
"This is the 103rd World Series. Only two teams have won successive championships by 4-0 sweeps: the Red Sox (2007, '04) and, before they began to self-destruct, the Yankees (1998-99)."
If i'm not mistaken, didn't the Reds sweep the Yankees in '76 and then sweep the A's in '90? Or am I missing something?
