South Korea's Ha Na Jang shot a flawless 4-under 68 on Saturday to grab a one-stroke lead heading into the final round of the HSBC Women's Champions tournament.

Chasing her second LPGA title this year, the 23-year-old racked up four birdies and her second straight bogey-free round to lead the tournament on 12-under 204 at the Sentosa Golf Club in Singapore.

Thailand's Pornanong Phatlum knocked in six birdies in her 68 to end the third round in outright second at 11-under, one clear of the South Korean pair of Amy Yang and Mirim Lee.

Yang reeled off five birdies in her last eight holes for a 68 to charge up the leaderboard while the overnight co-leader Lee signed for a 70 after a round with five birdies and three bogeys.
