Avondale, La. • Ricky Barnes birdied six of the last eight holes Thursday at rain-softened TPC Louisiana to take a one-stroke lead in the Zurich Classic.
Barnes finished the opening round with an eagle, seven birdies and a bogey for an 8-under 64. Boo Weekley and Lucas Glover were a stroke back, and D.A. Points and Morgan Hoffmann shot 66.
Guan Tianlang, the 14-year-old Chinese amateur playing on a sponsor exemption, opened with an even-par 72, highlighted by a 5-wood that he hit to a foot on the par-3 17th. He tied for 58th in the Masters after becoming the youngest player to make the cut at Augusta National, and said Thursday that he will play in a U.S. Open qualifier in two weeks in Dallas.
Defending champion Jason Duffner shot 70, and 2011 winner Bubba Watson had a 73.
rookie Caroline Masson shot a bogey-free 7-under 64 on Thursday to take a two-stroke lead over Carlota Ciganda after the first round of the inaugural North Texas LPGA Shootout at Irving, Texas.
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 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.
