Already the best amateur in women’s golf, Rose Zhang set another record Thursday to take a five-shot lead in the Augusta National Women’s Amateur, leaving her one round away at the home of the Masters from another big title.

Zhang opened with a 6-under 66 at Champions Retreat to set the tournament record. She went one lower Thursday with a 7-under 65 — despite making her only bogey of the tournament — and finished with a long chip to 3 feet for birdie.

“This is not a course where I can see a bogey-free 66. And what did she shoot today, 65? That doesn’t even enter my brain,” said Megha Ganne, who plays with Zhang at Stanford.

It trundled onto the green to 30 feet, and she made the eagle putt.

“All I was thinking was don’t hook it so far it goes into the trees,” she said with a laugh. “I was also thinking of not topping it.”

She was at 13-under 131.

No one else was within fewer than 10 shots of Zhang, a 19-year-old sophomore at Stanford and the reigning NCAA champion.

Zhang has a practice round Friday at Augusta National with the rest of the 72-player field, and then 31 players who made the cut at 2-over 146 will play the final round at the home of the Masters, which starts next week.

“From my past experience (with a big lead), it’s very important to know you have a whole field chasing you and anything can happen,” Zhang said. “Every hole, every score matters. I’m just going to play as hard as I can.”

The final round will include another 15-year-old in Gianna Clemente, who played her first U.S. Women’s Amateur at age 11 and last year made it through Monday qualifying for three consecutive LPGA Tour events.

Anna Davis, the defending champion, never recovered from a four-shot penalty she was assessed on her opening hole Wednesday for lifting and cleaning her golf ball when it wasn’t in the fairway. She had a 9 and shot 76. Davis had a pair of bogeys on par 5s and missed the cut by two shots.

Also making the cut were Amari Avery, the No. 9 player in the women’s amateur ranking, with birdies on her last two holes. The most unlikely to advance was Ting-Hsuan Huang of Taiwan. She opened with a 79 and bounced back with a 66 to make it to the final round with two shots to spare.
