Top guns expect a tough test at US Women's Open

Thai ace Jeeno says 'patience is the key'

- 

Top-ranked Nelly Korda, world No.2 Jeeno Thitikul and third-ranked Lydia Ko chase a major title none of them has won when the 80th US Women's Open tees off today.

Defending champion Yuka Saso of Japan seeks her third US Women's Open crown in five seasons at the par-72, 6,829-yard Erin Hills layout in Erin, Wisconsin.

"Conditions here can be very difficult," Saso said. "I think it's going to be a good challenge.

"It would be nice to win another one. Any other tournament would make me as happy, but if I win again, it would be more special. Winning keeps me motivated."

Korda, a two-time major champion, seeks the only major title on home soil that has eluded her.

"It's going to test everyone's game, very demanding," Korda said. "The bunkers are not easy. It doesn't really matter how far you hit it. It's all about accuracy at the end of the day.
