Rogers, Arkansas: World No. 1 Yani Tseng of Taiwan closed with an eagle to fire a five-under par 66 and grab a share of the lead after Friday's first round of the 54-hole LPGA Northwest Arkansas Championship.
Defending champion Tseng, seeking her eighth worldwide triumph of the year and 10th career LPGA victory in the $2 million event, was level atop the field with local heroine Stacy Lewis, who birdied three of the last four holes.
"I just focus on every shot," Tseng said. "I don't feel like I need to win this because I won last year. Every year is different. All the great players improve from the last year, so you never know."
