According to ESPN's Buster Olney, the Brewers were the third team in the rumored Jermaine Dye deal between the White Sox and Red Sox.
If they couldn't get one of Boston's elite prospects, the White Sox wanted Hideki Okajima from the Red Sox. That wasn't going to work, so Boston may have been trying to get Derrick Turnbow from Milwaukee for Chicago. The proposed deal ended up falling through last week, and it's unclear whether there's any chance of it being revisited.
