The two best teams in the Central the past two weeks are playing each other in Detroit. I won't rule out the White Sox either. Their defense, with Moncada at third and Anderson at short isn't bad. Their starting pitching is coming around and they have several good offensive players.
Detroit has been one of the most efficient defensive teams this year. They have a lot of good arms and a suspect offense, to be sure. If they can find guys to increase the offensive output, they might contend, but I think too many are a year away and they have had too many pitching injuries.
