DAVAO CITY — Yvon Bisera rattled off four birdies in a row from No. 1 on her way home as she recovered from a wobbly backside start to shoot a 71 and snatch the first day honors from Mikha Fortuna in the ICTSI South Pacific Classic on Tuesday.

Bisera used her power and banked on steady putting to make a big turnaround then endured a bogey on the sixth to gain the head-start in the 54-hole championship on her home turf at the South Pacific Golf & Leisure Estates here.

"My driving was quite steady and strong and my putting clicked," said Bisera after coming out on top while bucking the heat in a punishing start to the P1 million championship serving as the ninth leg of this year's Ladies Philippine Golf Tour.

"I'm used to this kind of weather since this is my home course," added Bisera, whose six-foot birdie putt on No. 1 sparked a run that included a tap-in birdie on the par-5 second hole which she reached in two, and a clutch pitch-in feat on the par-3 No. 3.

She capped her blitz with a long putt on the fourth but missed posting a two-shot cushion with a missed-green mishap on No. 6.
