Rolex Rankings No. 8 Jiyai Shin outdueled Lydia Ko and held off a surging world No. 1 Yani Tseng to capture the ISPS Handa Australian Women’s Open at Royal Canberra Golf Club.

Shin stamped her authority on the championship when she hit a perfectly executed lob wedge chip shot into the 14^th hole from thick rough.

The 24-year-old South Korean had stood on the 14^th tee tied with the 15-year-old Ko at 16 under par, but Ko took bogey after finding a fairway bunker and after Shin birdied the 15^th, it was effectively over for Ko, the winner of the previous week’s ISPS Handa New Zealand Open, who finished in third place as the leading amateur.

Tseng fired the low round of the day, a 66, to shoot up to second position. She was still in the hunt coming down the 18^th, but needing an eagle she hit her second shot into the trees left of the green and took a par.

Shin, who is once again a force in women’s golf after recovering from hand surgery last year, said the pressure that mounted over Sunday’s highlight made her lob wedge shot one of the best shots of her career.

“Well I think today this chip shot is much – make the important of this tournament because before when I chip it in, my play wasn’t bad,” said Shin. “But after chipped it in I get more in the legs and then more enjoy the other few holes. So it was great up and down for me.”

The 2012 Ricoh Women’s British Open champion said she could’ve taken relief but she preferred the lie she already had near the wooden fence fixture.

“Yes, from the ball to the hole around the 15 yard and then I hit a low wedge, 60 degree wedges and I hit a little bit high shot and then it was land perfectly,” said Shin. “Then the actual lie, the green lie was straight, so I just keep focus, hit it straight (laughs) because the fence is really close to the ball flight, so I just – I’m thinking, just keep headed down.”
