Phillies shortshop Jimmy Rollins is officially listed as day-to-day, but there appears to be a chance that he won't return in the regular season. Hamstrings can take time to heal and Rollins didn't sound very optimistic on Tuesday. "I hope so," said Rollins. "Studies show, even if it's a mild hamstring, even though the doctors like to say 7 to 10 days, it's usually 3 weeks. And that's at the mildest, before I can go and do what I need to do. But I'm not going to have 3 weeks. Three weeks, that puts us right at the playoffs, so I'm definitely going to try to do my best to come back before that."
