Dangerous weather conditions suspended play in the second round at 3:25 p.m. local time on Saturday at Pinnacle Country Club in Rogers, Ark. 'The course received 3.25 (inches) of rain last night and after having assessed the golf course and consulted with our meteorologist and superintendent, the golf course is unplayable,' the LPGA said in a statement. 'Based on the weather forecast for the remainder of today and all-day Monday and Tuesday, it is highly unlikely that 36 holes could be completed to make it an official event. With scores reverting to 18 holes, the scheduled 54-hole event will be unofficial with no CME points awarded.
