NORTH TEXAS LPGA SHOOTOUT
IRVING, Texas (AP)—LPGA Tour rookie Caroline Masson shot a bogey-free 7-under 64 to take a two-stroke lead over Carlota Ciganda after the first round of the inaugural North Texas LPGA Shootout.
Inbee Park, the No. 1 women's player in the world, was in a group at 67.
While Masson has made only one of five cuts in her first LPGA season, the 23-year-old German played on the Ladies European Tour the last three years and won the 2012 South African Women's Open. She closed with a curling putt from about 18 feet on the ninth hole, her longest birdie putt of the day.
Ciganda, from Spain, was the top rookie and top money winner on the European tour last year.
Taylor Coleman, a 16-year-old high school sophomore from San Antonio, shot 68.
Second-ranked Stacy Lewis, from The Woodlands near Houston, had a 72.

South Africa's Louis Oosthuizen was a stroke back with two holes left when darkness forced the suspension of play on the Blackstone course. The tournament is sanctioned by the European and Asian tours.
