NEW YORK – American Rose Zhang shot an immaculate nine under-par 63 to hold a two-stroke lead — and a six shot advantage over record-chasing Nelly Korda — after the first round of the LPGA's Founders Cup on Thursday (Friday in Manila).

Zhang's bogey-free round leaves world number one Korda with plenty of work to do if she is to mount a bid for an LPGA record sixth consecutive victory.

Korda's three-under 69 left her six shots behind the leader at Upper Montclair Country Club in Clifton, New Jersey.

The 25-year-old American equalled Annika Sorenstam and Nancy Lopez for the all-time record win streak of five in five starts by taking last month's Chevron Championship, beating Sweden's Maja Stark by two strokes in the year's first women's major championship.

After a two week break, she was quickly into her stride with a birdie on the par-5 second and the par-5 ninth but after another birdie on the 12th she bogeyed the par-4 13th.

Korda's round ended on a positive note with birdie on the final hole and she was happy with a solid return.

"There is still three more days. You still have a lot of things.... I know the weather is not supposed to be great and there is just different factors that go into the rest of the tournament," she said.

"So it's definitely nice to get a good round in. Still a long, long ways away from Sunday," she said.

"Overall a solid day. Didn't really make too many mistakes, and if I did — this golf course is very, very narrow off the tee — I kind of gave myself a good chance at par.

"So definitely got bailed out with my short game a couple times. Overall, it was a solid day," she added.

Zhang, however, received full rewards for her outstanding front nine, where she made six birdies including four in a row before reaching the turn.

She also left the course with the boost of a birdie on the 18th and the 20-year-old said she had been in an incredible groove, carding her career-low round on the LPGA Tour.

Zhang's only win on the LPGA came in New Jersey, where she won the Mizuho Americas Open in Jersey City in her first LPGA start as a professional last June.

Sweden's Madelene Sagstrom was two shots back of Zhang after her seven-under 65.
