Placido Polanco will not be able to return to action for the Tigers this season. "I am not going to play any more this year," Polanco said, stunning the assembled media and his teammates. "My shoulder. I just can't do it. I am out for the year." Polanco has been out with a left shoulder separation since Aug. 15. He took batting practice on Saturday, and the Tigers were hopeful he could return sometime this week.
