"It has become increasingly unlikely that left fielder Carlos Guillen will return to the Detroit Tigers' lineup any earlier than one month from now. And Guillen's season will be in jeopardy if his right shoulder doesn't improve soon.
Guillen's agent, Peter Greenberg, said Monday that there could be a drop-dead date on the decision to have surgery sometime in July, in order to afford Guillen the best chance at making a full recovery before the 2010 season.
Greenberg acknowledged that off-season surgery is a possibility, even if the 33-year-old returns to action this year.
"He is trying to do everything he can to avoid surgery, especially since it's his throwing shoulder," Greenberg said.
According to that timetable, Tigers officials should have definitive word on Guillen's status before the July 31 non-waiver trade deadline. A power bat is currently one of the team's biggest needs; Detroit ranks among the bottom third of major league teams in production from both corner outfield spots.
