Japan's Harukyo Nomura pulled herself into contention by shooting a 3-under 69 Friday to sit four shots behind leader Feng Shanshan after two rounds at the U.S. Women's Open.

Nomura carded four birdies and a single bogey for a 36-hole total of 4-under to share sixth place with three others, while Feng saw her overnight lead cut to two shots after a second-round 70 at the Trump National Golf Club.

"It's nice to play under pressure in a major championship. I did okay," said Nomura.

"It was good that I got two birdies on the front nine despite the rain. In these difficult circumstances, a 3-under is a passing grade. Both my long and short game is improving so I'm looking forward to the remaining two days."

Ai Miyazato, who is looking to earn her first major title before she retires at the end of the season, and Rumi Yoshiba, who entered the second round in third, were among the 62 players who finished the round on the right side of the 2-over cut line.

Three South Koreans -- Choi Hye Jin, Lee Jeon Geun and Amy Yang -- are tied for second two shots behind China's Feng.

With club owner and U.S. President Donald Trump watching from a private box near the 15th green, Miyazato snuck into the weekend at 1-over-par after claiming two of her three birdies in the final four holes. She needed the late flurry after finding water for a double at the seventh and taking a bogey on 13 after she was hung up in a bunker.

"I didn't see him, but I heard screaming and cheering so I was saying (to my caddy) maybe he's here," said Miyazato of Trump's arrival.

"I achieved my minimum goal. I kept missing my putts and it was one of those days where I had to convert the few chances I had. I'm happy to qualify (for the final two rounds) but I want to see more convincing play on the greens," she said.

After a competitive first-round 68, Yoshiba slipped back to a tie for 31st on Friday, closing out her round with a 4-over 76.

Her day started with a horror seven on the par-5 first and she followed it with three further dropped shots, only one birdie stemming the damage.
