Ryu widens lead in Ontario

London, ON ( - Following her course-record 63 in the opening round, So Yeon Ryu fired a 6-under 66 on Friday to widen her lead to five heading into the weekend at the Canadian Pacific Women's Open.

Ryu, who entered the second round with a 1-shot lead, finished 36 holes at 15- under 129, five shots clear of Anna Nordqvist, Danielle Kang and Na Yeon Choi. Choi was right behind Ryu after her 64 on Thursday at London Hunt and Country Club.

Ryu is looking for her third career victory on the LPGA Tour, with her last one coming at the 2012 Jamie Farr Owens Toledo Classic. Ryu has nine top-10 finishes this season.

"A lot of birdies still this time, but no bogeys is still more a great sign because it means I've played really consistent," said Ryu. "When I was in trouble, I proved I can prove it with a bogey-free round, so I'm more happy with a bogey-free round."

Kang (68), Nordqvist (69) and Choi (70) are the closest players to Ryu at 10- under 134.

Cristie Kerr shot a 4-under 68 on Friday and she is alone in fifth at minus-9. Brittany Lincicome, who lost to Inbee Park on the first playoff at last week's LPGA Championship, shot a 65 and she is tied for sixth at 8-under 136. Lincicome was joined there by Lizette Salas (66), Lindsey Wright (69), Mi Hyang Lee (69) and Xi Yu Lin (70).

Ryu started her second round on the back nine and began with two straight pars from 10. She then rattled off back-to-back birdies followed by another birdie at 15 to get to 12-under early.

Following four straight pars from 16, Ryu rolled to three straight gains from No. 2. Ryu finished her second round with five straight pars to complete her second consecutive bogey-free round.

"After I shot 9-under, 6-under is not that great, but still it's a really great score, and I did a lot of great putts," Ryu said. "I had a bogey-free round two days in a row, so I feel really great about that. I do love Canadian fans so much. I'm really happy I was able to show really great golf in front of them."

Kang also had a bogey-free day on Friday with four birdies at four, seven, nine and 18. Kang has just one bogey through 36 holes and she has made 11 birdies.

After her bogey-free round on Thursday, Nordqvist tripped to one on 16 in round two, but she also drained four birdies on Friday to grab a share of second place.

Choi scattered four birdies on day two as well, but she also tripped to bogeys at five and 11.

NOTES: Ryu has yet to win on tour this year, with her best finish coming at the Marathon Classic where she finished runner-up to Lydia Ko ... Ko, who is the two-time defending champion at this event, is tied for 24th at 5-under following her second-round 69 ... With the cut falling at 1-under 143, 87 players advanced to the weekend.
