Kim Song-hee fired a nine-under 62 to set the 18-hole record and surge into a tie for first place after two rounds of the LPGA's Canadian Women's Open on Friday.

The 21-year-old South Korean shattered the previous mark of 64 which was set on four different courses and matched eight times.

She is tied at nine-under 133 with Norway's Suzann Pettersen who posted a three-under 68 Friday on Calgary's Priddis Greens which is hosting the event for the first time.

Catriona Matthew (66) and world number one Lorena Ochoa (68) are tied for third place at eight under par.

Ochoa won here in 2008. She made bogey on two of the last three holes to fall out of sole possession of first.

MJ Hur (67), Angela Stanford (65) and Sun Young Yoo (66) are tied for fifth at seven-under-par 135.

The 21-year-old Kim is seeking her first win on the LPGA Tour posted six straight birdies.

"I thought I couldn't make all the birdie putts, even though I hit it my second shot on the green and make a birdie," Kim said. "I didn't know I had six birdies in a row, it was awesome. I mean it was fantastic."

Pettersen is hoping to end a two-year drought with a win here. She won five times in 2007. Pettersen began on the back nine and rolled in three straight birdies, finishing the run off by two-putting on the par-five 12th.

"I tried to play my own game. I got off to a great start," said Pettersen.

"I had three birdies on my first three holes. I gave myself a lot of putts, and I was rolling the putts nicely. A few kind of annoying bogeys out there, especially the two coming in.

"But like I said, there's a lot more golf to be played."

First-round leader Anna Rawson of Australia stumbled to a two-over 73 to slide into a tie for 10th place at five-under-par 137.
