A state appeals court in Boston says a Massachusetts women who was hit in the head by a foul ball at Fenway Park cannot sue. Jane Costa was severely injured in 1998 when she was struck by a ball while sitting in the stands at a Red Sox game. She had to undergo extensive reconstructive surgery. But in its ruling yesterday, the court said the Red Sox had no duty to warn her of the possibility she'd get hit. The court says the danger is obvious. It says a central feature of baseball is that batters "forcefully hit balls that may go astray from their intended direction." The Red Sox say about three to four dozen fans get hit by foul balls every season.
