Vallejo, Calif. Dorothy Delasin is playing her best golf in a place where everybody seems to know her name.
With the gallery shouting constant encouragement, Delasin birdied three of the final four holes to move one stroke ahead of Karrie Webb and Se Ri Pak on Saturday at the Samsung World Championship.
Delasin, a 21-year-old second-year pro who grew up in the San Francisco Bay area, had a 5-under 67 for a 208 total. She waved and blew a kiss to the gallery after tapping in her final putt.
"It's cool. It's like people saying 'Tiger!' or 'Sergio!"' Delasin said. "Now, they're saying 'Dorothy! Dorothy!"'
Webb, who started strong but had just one birdie in the final 11 holes, shot a 70. Pak, who tied Delasin for the first-round lead, fought off a stiff neck muscle for a bogey-free 67.
Delasin learned the game on San Francisco's municipal courses, and her family still lives in South San Francisco. She declined college scholarship offers to turn pro before last season, when she became the youngest player to win an LPGA event since 1975.
She has been the clear crowd favorite at the event, which pits 20 of the world's top women players against each other at Hiddenbrooke Golf Club in the suburban hills northeast of the Bay.
After hanging behind second-round leader Webb with steady play for most of the day, Delasin passed the two-time Player of the Year with birdies on the final two holes. She nearly eagled the par-5 18th, but her 30-foot putt sat on the lip of the cup.
