Stupples in the hunt at LPGA major

WILMINGTON, Del. -- Annika Sorenstam got mad and finished with two birdies. Grace Park got a good break and then ended her round with two bogeys. Both wound up chasing Jennifer Rosales, who played a steady hand Thursday with a 5-under 66 in the LPGA Championship.

Rosales, who picked up her first LPGA victory last month in Atlanta, took advantage of the par 5s and never came seriously close to a bogey at difficult DuPont Country Club to take a one-shot lead over Karen Stupples, Gloria Park and Chiharu Yamaguchi.

It took her to her first 18-hole lead on the LPGA Tour -- at a major, no less.

But the 25-year-old Filipino, who won the NCAA title as a freshman at Southern Cal, must contend with Sorenstam and Park, only two shots behind at 68.

Sorenstam birdied two of her first three holes to make her presence felt quickly on a steamy day at DuPont

Stupples is seeking her second victory of the year and first career major.

PGA TourVijay Singh shot an 8-under 63 to take the first-round lead in the Buick Classic, the final PGA Tour event before the U.S. Open next week at Shinnecock Hills.

Singh, seeking his third victory in the tournament, played his final nine holes -- the front nine on the Westchester Country Club course -- in 6-under 30 to take a one-stroke lead over Fredrik Jacobson.

David Frost, the 1992 winner on the hilly, tree-lined course, opened with a 66, and Fred Couples topped a large group at 67. Ernie Els, a two-time Buick Classic champion coming off a victory Sunday in the Memorial, was five strokes back at 68.
