Veteran outfielder Marquis Grissom ended what he called a "fun ride" and retired from baseball Tuesday, ending his career after 17 seasons. "When it's time, it's time," Grissom said. "I think this is the best thing for me, at this point, to officially hang the cleats up and go home and enjoy the second half of my life and do things I've always wanted to do." Grissom, 38, was a non-roster invitee in the Chicago Cubs camp and his decision creates an opening for Angel Pagan to make the team as a backup outfielder.
