Jose Guillen told Enrique Rojas of ESPNDeportes that he will call it a career if he doesn't have a contract offer within a week (link in Spanish). Guillen says he has told his agent to gauge interest around the league in case teams are looking for an outfielder/DH. And if no teams come calling, Guillen says he'll walk away from the game.
"If I don't have any offers within a week, I will retire from baseball permanently," Guillen said, before explaining that he's ready to play after a trying 2010 season. "If I receive an attractive offer, I'm willing to try. Otherwise, I know that it's over."
Guillen, 34, posted a .258/.314/.416 line with 19 homers for the Royals and Giants last year. He struggled with neck injuries, dealt with an HGH investigation and was left off of the Giants' playoff roster.
