Obviously without Liriano the Twins are less intimidating, but assuming he is back they have one hell of a rotation. The falling apart old man Radke has a 3.12 ERA and a 1.06 ERA since the ASB. He's gotten his act together, and is a huge reason why they've managed to stay in the WC race with Liriano out. This is Radke's last season, and he's doing all he can to keep himself on the mound, taking cortizone shots instead of getting surgery on his shoulder. For the time being it's working, but it is possible it will catch up to him in October.
The Twins lineup is nothing to sneeze at, although could you imagine what they'd look like if the GM pulled the trigger on a deal for Soriano? Nontheless Mauer is leading the league in hitting, and his OPS is .948, Morneau is hitting the piss out of the ball with 32 homers and 110 RBIs. As a team they have the highest batting average in the MLB. Guys like Castillo, Punto, Cuddyer, Hunter comprise a good, balanced lineup.
While the White Sox probably have the best 3-4-5 in baseball, it's the pitching that makes me confident. Not one of those guys scare me right now, Contreras is not even close to being the same pitcher he was with a 5.90 ERA Post-ASB. Garland, Garcia, Buehrle all have BAA over .285 and Vazquez' ERA is Unit-esque at 5.06. In the playoffs I'll always take my chances on the team with weak pitching.
The Twins have two shut down pitchers and a third who has been phenomenal in the second half, while the White Sox have emminently hittable pitching. I'll take my chances with the defending champs in this one.
All that said, I really don't think it matters who we play. The Yankees should take the whole f***in' thing.
