Red Sox left fielder Carl Crawford continues to rehab his left hamstring strain and was finally able to run the bases Tuesday afternoon at Fenway Park. Crawford suffered the injury and was placed on the disabled list on June 18. "He had a really good day. It's been about three days in a row now," said Red Sox manager Terry Francona. "We'll keep letting him do that and I would think in the not-too-distant future we'll be talking about him coming back. When that is, I don't know, but he's doing real well." "We want him to be able to play and not think about running. That's so much a part of his game," Francona added.
