Not a short series, where I will fully admit the A's wouldn't have enough frontline pitching. But everyone plays everyone-- either one or two games. Now Tomko being shut down would change my view, but before that development here are the teams that I believe would definitely finish ahead of the A's:
St Louis Cardinals
And that's it. The Giants, Phillies and Dodgers would be very close to the A's, IMHO. Frankly we're playing better ball than any of them right now and are stronger in the bullpen over all save the Dodgers. I think the A's would outplay the Marlins, Braves, Rangers, Tigers, Twins and other pseudo-contenders. And they're flat-out playing much better ball than just about every other team.
Interesting off-season because while the debate will undoubtedly be stoked around here as to whether or not to go for it in 2010, I believe BB is going to try to get a pitcher and perhaps a SS to do just that.
