SAN MARTIN, Calif. — When Sung Hyun Park entered her first U.S. Women's Open, her goals were modest. Halfway through the tournament, Park has put herself in prime position to contend.
Park capitalized on favorable morning scoring conditions, shooting 6-under 72 Friday to take a two-stroke lead after the second round of the U.S. Women's Open at CordeValle.
"I didn't even think about winning because this is the first time for me," Park, a 22-year-old from South Korea, said through an interpreter. "I would like more experience with the USGA, LPGA. But I'm trying to enjoy this tournament. That's why I am just more comfortable, don't even think about the winning, I just enjoy the play. That's why it happened today."
Park made her LPGA debut last year when she finished second at the KEB-HanaBank Championship in South Korea. She has played three LPGA tournaments this year, tying for sixth in her first major at the ANA Inspiration in the spring.
Park drove into a hazard on the par-5 18th for a one-shot penalty before saving par with a 15-foot putt.
Amy Yang shot a 71 to get to 6 under, tied for second with first-round leader Mirim Lee. World No. 1 Lydia Ko bounced back from a 1-over par first round to shoot 66 for a tie for fourth with Haru Nomura.
Among players who missed the cut at 4 over were last year's winner In Gee Chun, 2014 U.S. Open champion Michelle Wie and 1998 winner Se Ri Pak.
Pak, whose success helped lead to the surge of South Koreans on the tour, double-bogeyed her final hole to finish at 80 on the day and plus-9 in her final scheduled tournament in the United States.
Some players, including Karrie Webb and Christina Kim, came back to the 18th green to watch Pak's final shot and congratulate her on her career.
In other news, Martha Burk is encouraging people to join a protest over the U.S. Women's Open being held next year at Trump National in New Jersey. In 2002 Burk challenged Augusta National to invite a female member.
CHAMPIONS: Scott Dunlap shot 8-under 64 to take the first-round lead at the Dick's Sporting Goods Open in Endicott, N.Y.
Dunlap began with a bogey at No. 1, then rallied with four birdies in a five-hole span before the turn at En-Joie Golf Club and reeled off five straight birdies to start the back nine. He leads Glen Day, Bart Bryant, and John Riegger, who were tied for second at 66.
"Well, bogeying the first hole is usually my best way to start a round," Dunlap said with a smile. "I did that, so I knew it was going to be a good day."
Gibby Gilbert III, Kevin Sutherland, Paul Goydos and Joe Durant were at 67.
Frenchman Jean Van de Velde shot 75 in his Champions Tour debut.
