The 60-year-old Mourgue D'Algue, the runner-up in the 1999 tournament, had the lone sub-par round of the day to finish with a two-round total of 3-over 145.
'Yesterday morning I was out early and the wind picked up and it was quite cold,' Mourgue D'Algue said. 'It turned around nicely. It was one of these days where I got the nice putts in. If I hit one putt a little bit hard, I managed to get the second one in. It was that kind of a day. It was very nice.'
Nancy Smith of North Port, Fla., shot her second straight 73 to earn the second spot at 4 over, and 2004 winner Carolyn Creekmore of Dallas and Anna Schultz of Rockwall, Texas, had 72s to tie for third at 6 over.
'I was playing pretty well today and I thought maybe I'd do it,' the 59-year-old Smith said. 'But I made too many bogeys and not enough birdies on the back side. But I'm very pleased with myself.'
Carol Semple Thompson, the 57-year-old star from Sewickley, Pa., who beat Mourgue D'Algue in 19 holes in the 1999 final for the first of her four consecutive titles, followed her opening 79 with a 75 to earn a spot with a 14th-place tie at 12 over.
Defending champion Diane Lang of Weston, Fla., tied for 20th at 14 over with rounds of 79 and 77.
'I was happier, but still not happy,' Lang said. 'My irons were still not good. So I went back to the range and it feels a lot better. I think I figured something out.'
Marlene Streit, the 72-year-old Canadian player who has won four USGA titles, also advanced, shooting 79-82 to tie for 37th at 19 over.
