Rancho Mirage, Calif. ? Annika Sorenstam had reason to celebrate Sunday, and celebrate she did.

She was doused in champagne after sinking her putt on the final hole before taking the traditional winner’s plunge into the pond next to the 18th green along with sister Charlotta and mother Gunilla.

“I’m going to remember this Easter weekend for a long time,” Sorenstam said after shooting a final-round 68 and winning the Nabisco Championship by eight shots and extending her LPGA Tour win streak to five.

Sorenstam was so dominating with 10 birdies and no bogeys over the final 36 holes that fellow competitors only could marvel at the new heights her game is reaching.

“It only shows that she’s that much better than the rest of us,” defending champion Grace Park said.

The victory was Sorenstam’s fifth in a row over two seasons, tying a record set by Nancy Lopez in 1978. It also was the 59th LPGA Tour victory of her career — a number Sorenstam is very familiar with — and her eighth major-championship win.

She finished 15 under, eight shots ahead of Rosie Jones and 10 ahead of the next two challengers, Laura Diaz and Cristie Kerr.

“Somebody said you didn’t make it exciting,” she said. “But for me it was exciting.”
