Taking a look at World Series history, how many back to back champions have there been? Since 1990, only the Blue Jays (92-93) and the Yankees (98-00) have done such a feat. In fact, even making it to the fall classic back-to-back is an accomplishment in itself, so the Rangers making it again this year convinced me to take a further look. 

Looks like winning the second time around isn't all that rare. My beloved Oakland A's won in 1989 after losing in 1988 and 1990. With the series tied at 1-1, lets see how they do.
