Cristie Kerr won the rain-delayed LPGA State Farm Classic by one shot over Anna Nordqvist and Na Yeon Choi on Monday. The final round of the event was played Monday due to weekend rains interrupting play. Kerr fought off flulike symptoms and late challenges from Nordqvist and Choi to win with a tournament-record total of 22-under 266 at Panther Creek Country Club.
