China's Feng Shanshan takes one-stroke lead at Reignwood Classic

Chinese golfer Feng Shanshan shot a nine-under 64 to take a one-stroke lead over American Stacy Lewis after the third round of the Reignwood LPGA Classic.

Shrouded in smog, Feng carded nine birdies in a bogey-free round for a total of 21-under 198, boosting the chances of a home winner in the first LPGA tournament played in the country.

Feng was in a two-way duel with Lewis all day before grabbing the outright lead for good with a birdie on 16. Both players added birdies on the final two holes, making for a total of eight for Lewis, who remains bogey-free in the tournament.

Feng said she expects a similar duel in today's final round.

"I've played Stacy many times. I know she's a very aggressive player, and I know that on this course she could definitely drain a lot of birdies and chase back. I knew the lead wasn't secure," said Feng, who won last year's LPGA Championship to become the first Chinese major winner. "A one-stroke lead is very small. There are 18 holes left so there's still a challenge. If the conditions are right, you can get a very low score on this course."

The start of play was delayed because of the high levels of smog. Several players, including Korda, donned surgical masks in hopes of filtering out some of the pollution.

Top-ranked Park In-bee was another four strokes back in third after finishing with four straight birdies for a 66.
