Taiwan's Yani Tseng takes lead at Yokohama Tire LPGA Classic

Taiwan's Yani Tseng stormed into the lead after the weather-disrupted second round of the Yokohama Tire LPGA Classic after a stunning eagle-birdie finish in Alabama.

The former world No 1 covered her final six holes in five under par to card a flawless eight-under 64 on the Senator Course at Robert Trent Jones Golf Trail in Prattville.

Tseng struck a six-iron to four feet to set up an eagle at her 17th hole, the par-five eighth, before being frustrated by a 96-minute weather delay due to the threat of lightning.

Tseng has not won an LPGA event since 2012 but feels that she is moving in the right direction to claim her 16th career victory soon.

"It's just exciting. (I am) just very happy my game's really coming back... I want to win... It will come," she said.

"It doesn't matter if it's this week or next week or next year."

Behind Tseng, Ernst and Thompson spurred each other on and recorded a combined 13 birdies and an eagle.

"We both had a string of birdies there on the front nine," said Ernst.

"She was hitting it well. Definitely when you see putts going in with other people, too, I think it just kind of gives you a little bit more confidence that you can just take it deep."
