Nationals second baseman Daniel Murphy ambled around the team's annual fan festival with the aid of a pair of crutches and declined to offer any sort of estimate about the length of his recovery from right knee surgery.

"I don't want to put any timetables on it, because if you miss 'em, you guys get really fishy when stuff like that happens," Murphy said Saturday, sitting on a chair during his session with reporters about eight weeks after the operation.
