In the AL, I'm going with the Sox. White Sox, that is. I can't stand rooting for LaRussa's team, but they have some wow high end talent.
As for the bracket, Red Sox over NYY in WC, White Sox over Astros and Rays over Red Sox in the ALDS, then White Sox for the AL pennant and World Series.
In the NL, Cards over LAD in the WC, Giants over Cards and Brewers over Barves in the NLDS, Brewers for the NL pennant.
