White Sox manager Robin Ventura indicated Friday that who he uses as a closer could depend on the matchup. Obviously, it's not what fantasy owners want to hear, and it's the opposite of what pitching coach Don Cooper said in the Chicago Sun-Times. "No, we are not doing committee,'' Cooper said. "There will be a set closer.'' Matt Thornton is still probably the best bet for saves, but Jesse Crain, Addison Reed and Hector Santiago could all be in the mix.
