NAPLES - Thailand's Pornanong Phatlum fired a bogey-free five-under par 67 on Saturday to seize a share of the LPGA Titleholders third-round lead alongside Natalie Gulbis and Gerina Piller. Gulbis shook off a watery bogey at the par-five first hole at Tiburon Golf Club and carded eight birdies in a seven-under 65. It was her best round since the final day of the 2012 Kraft Nabisco Championship, and Gulbis said it was the product of recent hard work with coach Butch Harmon on getting used to some new irons. "As any player knows it's quite a process to change irons and switch to the new TaylorMade irons and just spent a lot of time with Butch redoing every aspect of my game and just working on fundamentals," she said. Piller and Pornanong are both fighting for a first career LPGA title.–AFP
