Coco Crisp has no doubts he's ready to join the Boston Red Sox. Crisp, on the disabled list since April 9 with a non-displaced fracture at the base of his left index finger, played center field and batted leadoff Saturday in a rehabilitation game for the Triple-A Pawtucket Red Sox against the Norfolk Tides. Crisp drove in the first two runs in Pawtucket's 4-0 victory with a two-run single off losing pitcher Jason Scobie. Crisp was 1-for-3 with a walk in four plate appearances.
