It's Gasser--last time, his start was pretty solid compared to his other ones, so I would have faith. Buetane can only do so much before his old body aches.
More seriously, though, I would be shocked if the Brewers did not win today--it seems improbable, but not impossible. They have to score the first run to be effective and gain momentum, though. Currently, I bet that Mitchell will do something awesome--his hard-hit percentage is up, and every advanced statistical indication shows that he's hot.
What do you guys all think about, like, the Brewers winning the NLDS and advancing to the NLCS? What is worse: Dodgers or Brewers? (Maybe even the negotiations will be impacted by the winner of the WS... who knows... so maybe even Sox hate will be an ironic bite in the ass.)
