Much was expected of Rose Zhang when she turned professional last week, and she is already delivering.

The two-time NCAA champion moved into position to win in her pro debut, shooting a 6-under 66 on Saturday to take a two-shot lead into the final round of the LPGA Tour’s Mizuho Americans Open.

“I’ve been in this position before, but I haven’t been in this position as a professional, since this is my first week, so I’m really just learning everything that I could,” Zhang said. “Tomorrow, I’ll be just trying to figure out what it feels like to be in the final group, navigate my way through, and I’m sure by the end of the day I’ll be able to, you know, just build my character more.”

The former Stanford star had six birdies in a bogey-free round on a raw, overcast day at Liberty National in jumping to the top of the leaderboard. It’s nothing new for the 20-year-old who won 12 of 20 events in her two years in college, with many viewing it as a sign of things to come.

Event 1 is certainly shaping up that way a day to go, and it could have been better. Zhang settled for a tap-in birdie at the driveable 16th hole after hitting her tee shot within about 5 feet.

Cheyenne Knight, who was tied with Minjee Lee for the halfway lead at 7 under, was tied for second with Atthaya Thitikul and Aditi Ashok, who both shot 68s. Knight had a 69, making a bogey at No, 17 and missing a 10-footer for birdie on the final hole.

Lee (72) was 7 under in fifth place, a shot ahead of Jennifer Kupcho (69) rookie Hae Ran Ryu (66) and Eun-Hee Ji (70).

Stephanie Kyriacoiu of Australia had the best round of the day, shooting a 65 that included an eagle, six birdies and an early bogey. The 22-year-old was at 5 under along with top-ranked Jin Young Ko (73) and fellow South Korean player Sei Young Kim (70).

They will all have to catch Zhang, who was the No. 1 women’s amateur for 141 weeks. She also is on a roll, having won the Augusta National Women’s Amateur this year and her second straight NCAA title last month.

This has been a hectic week for Zhang. Not only did she turn pro, but she has shown a lot of composure on the course and off with all the interview requests.

“I still think I’m human so I do feel little small butterflies here and there,” the Irvine resident said, “I’ve been pretty comfortable when I’ve been on the golf course. I’ve been able to tap into my zone and I’ve just been trying to think about how this is the sport that I’ve been playing for the last ten or so years. I’m just doing what I need to do and going back to what my body knows.”

Seven women have won their first start as a pro on the LPGA Tour since 1992, with Hinako Shibuno of Japan the last in the 2019 Women’s British Open.

PGA Tour

Rory McIlroy realized Muirfield Village was playing so tough that he set a goal of just trying to break 70. He didn’t quite get there, and his 2-under 70 still was enough for him to share the lead in the Memorial.

“I was really happy with how I scored out there, and how I just sort of hung in there for most of the day,” McIlroy said.

It helped that Hideki Matsuyama went from leading to dropping off the leaderboard in a span of six holes. And that Patrick Cantlay went into the water and over the green on his way to a triple bogey. David Lipsky bogeyed his last two holes.

What remained amid a few rumbles of thunder — but no weather delays — was an opportunity for just about everyone who had a tee time today.

Thirteen players were separated by two shots. Nine more were only three shots out of the lead.

Jordan Smith and Alexander Björk were among the golfers in a six-way tie for the lead heading into the final round of the European Open.

The others at 6 under include Tom McKibbin, David Law, John Axelsen and Julien Guerrier.
