Twins offense has struck out the most in baseball I think. It's not scary at all. Their starting rotation with Ryan, Gray and Lopez in a 3 game series could be tough. Ober has been pretty good as well. Like you said, opposite of the O's who have a great lineup and shut down pen, but lacking in their starting rotation.
Difference with winning WC3 and facing the Twins, if you advance you get the deGromless Rangers in the DS likely if they hold onto the division, which is a plus.
