Despite Joba Chamberlain's drunk-driving arrest in Nebraska over the weekend, Yankees owner Hank Steinbrenner says he is "100 percent" behind his pitcher. "He knows he made a mistake, and he's come out and said that," Steinbrenner said today in a Manhattan press conference. "We've always said that we're an extended family. The Yankee family." OMG, does that mean that Joba is soon going to be related to Madonna?? [Newsday]
