I can see people saying the Cardinals, Red Sox, Giants, or Dodgers. Maybe even Braves or Cubs (probably not either, though).
Anyways, I say second because it's basically uncontested that the Yankees are the best. Nobody has 2.5 times the rings they have, and they have 39 pennants (second place has 22). They have had some of the best managers in history, and a team of their best players would absolutely dominate every other team. They finished first in 44 seasons. For a bad part, they have 22 seasons under .500 (although they have 87 over, 56 over .600, and three over .700). They have 18 100 win seasons and in seven WS victories, they swept the other team. It's uncontested.
Anyways, back to the question, who do you think?
* Active franchises, as the second answerer said, by the way.
