The Marlins went into Friday 18 games under .500 but manager Ozzie Guillen didn't sound like a man worried about losing his job. "Can I say something about those (rumors)? Ha, ha, ha," Guillen said. "I laugh at that (expletive). I don't worry about what people say about that. I don't." Guillen said owner Jeffrey Loria has not spoken to him about keeping him beyond this season -- even though Guillen signed a four-year, $10-million contract last September. But Guillen, who is owed $7 1/2 million over the final three years of the contract, said he expects to be back. "The last thing that goes through my mind every day (is) if I'm going to have a job next year," Guillen said. "If Jeffrey thinks I don't do the job I should do, it's not the first time he's fired a manager." The Marlins have had six different managers since Loria took control of the team in 2002. "Look yourself in the mirror and ask why so many (expletive) managers come through here," Guillen said.
