The final round was suspended due to darkness as the tournament has had problems since the opening round. There were so many rulings on Friday that the pace of play was amazingly slow.
A three-and-a-half-hour fog delay pushed back the start of Saturday's action, meaning the second round would not be able to be completed until Sunday at the earliest.
The second round finished on Sunday afternoon, but the final round will be completed Monday morning. The field will be back at the Trump National Golf Club of Los Angeles at 11:00 a.m. (ET) Monday to complete the tournament.
Catriona Matthew is 3 under par in her final round and is tied for second place with Frenchwoman Karine Icher, who is 1 over par. The pair is knotted at 8 under par for the tournament.
Women's British Open champion Jeong Jang is 2 over through eight holes, but is part of a group tied for fourth place at minus-7. Natalie Gulbis is even through eight, Young Jo is three-under through 12 and Soo-Yun Kang is 2 under through nine.
Beth Daniel, Jamie Hullett and Marisa Baena are all 1 under through 11 holes. Mi Hyun Kim is even through nine holes, but the foursome is knotted at 6 under par.
Defending champion Annika Sorenstam is 1-under through 14 holes and stands at 4-under par for the championship.
