Washington Nationals outfielder Jose Guillen will have arthroscopic surgery Monday on his left shoulder, which bothered him throughout the second half of last season. Guillen, speaking after helping the team unveil its new alternate caps and jerseys at a sporting goods store Saturday, expects to be healed before next season. "We decided to get it done, get it out of the way," he said. "We've just got to repair this stuff, and hopefully I'll be ready for spring training."
