Say the Red Sox got Garza, and Lester and Beckett turned it around... I don't think using Lester, Beckett or Buchholz in the WC play in game would kill us in a short series... especially since the format this year is WC winner gets games 1 and 2 at home followed by 3 at the divisonal leaders.
Also remember, we can play a divisonal team in the first round this year, so it is very possible that we could see the NYY in the first round, with the way things are lining up.
