Farmer, Cahill and Lawless Score Home Run for Baseball Venue

Jana Farmer (Partner-White Plains, NY), Pat Lawless (Partner-New York, NY) and John Cahill (Associate-White Plains, NY) secured summary judgment in a Little League matter pending before the New York Supreme Court, Suffolk County on the eve of mediation. The plaintiff, a spectator at our client town and Little League franchise baseball game, was struck by a foul ball from another field. She alleged a concussion, TBI and other neuropsychological symptoms as a result. Throughout discovery, Jana, Pat and John established that the plaintiff was a dedicated “baseball mom” who regularly attended professional games and watched baseball on TV. She was aware of the risks of being hit by foul balls. The court noted that our clients had provided adequate protective screening and were able to demonstrate through an experienced baseball field design expert that the protections they offered exceeded industry standards.
