The World’s No.1 and 2, Inbee Park and Suzann Pettersen, will go head to head in a final-round battle for the World Ladies Championship on Sunday after they tied for the third round lead at Mission Hills in Haikou, China.

Park fired a course record 11-under-par 62 in warm and breezy conditions on the signature Blackstone Course to join rival Pettersen at the top of the leader board on 18 under.

Ye Na Chung sits four strokes behind on 14 under after a third round of 68. An eagle on the par-4 16th was the day’s highlight for the KLPGA Tour player.

Minjee Lee (69) is the leading amateur in a share of sixth place on 11-under, two shots better than fellow Australian Nikki Campbell (73).

Park birdied three of the first six holes but really started firing in the middle of her round with six birdies in a row from the ninth.

She picked up two more shots on 16 and the last for the best round of her career.

Park’s score in relation to par ties the all-time record low round for 18 holes on the Ladies European Tour, set by six other players.

Her back nine score, of seven under, also tied the LET record for nine holes.

It could have been even lower as she missed a short putt for eagle on hole 12 and two-putted from 20 feet for birdie on the long 18th.

“The last couple of days the putting has been really hard. These greens are a little bit grainy and much slower,” the Korean said.

“We played on very fast greens the last two weeks and I just came here and I wasn’t used to the greens.”

Norway’s Pettersen, leader after each of the first two rounds, opened with a bogey but hit back with eight birdies, including one at the 18th, to end the day level with Park.

“Today wasn’t an easy ride but with all the holes coming up you just have to be patient,” Pettersen said.

“I hit a great putt on 11, missed a putt and then parred No.12 after just having a 7-iron left.

“If you have a par there you drop two or three shots to the field. I’m in a good position for tomorrow and it’s going to be a nice battle again.”
