Boston Red Sox have won 3 World Series in the 21st Century and the New York Yankees have won zero (last one was in 2000 which was still 20th Century).
I do have beer however and I intend to go on drinking for another hour or so as I have not seen a World Series win in Fenway Park during my lifetime.
Enjoy.
Yankees won in 2009.
How about this, the Red Sox have won 3 since the last time the other cursed team, the Cubs, last won a playoff game!
