Tony Gwynn, who has joined with movie producer Thomas Tull in an effort to buy the Padres, owes more than $400,000 in unpaid federal income taxes, according to a report by the San Diego Union-Tribune. Tax notices show the Hall of Famer owes the government money from 2003, 2007 and 2009. Gwynn's tax attorney, Mitch Dubick, says his client is working to pay down the taxes and doesn't believe the issue will have a bearing on his role with the ownership group.
