Pauline del Rosario shot an eagle-aided four-under 68 to seize a three-stroke lead over defending champion Supamas Sangchan of Thailand at the start of the 2014 Champion Infinity Philippine Ladies Open Golf Championship in Antipolo on Wednesday. Del Rosario, who racked up six victories last year, including the Malaysia Kids World and the Singapore Juniors, settled down at the front after a rollercoaster start at the back, hitting two birdies from close range on Nos. 1 and 4 and a chip-in on No. 5 to complete a 33-35 card. Singapore’s Amelia Yong matched par 72 while Southwoods’ Miya Legaspi, the reigning Asian Youth Games gold medallist, turned in a 73 and young Mikhaela Fortuna of The Country Club carded a 74.
