Lydia Ko/Harry How/Getty Images The third round of the CN Canadian Women s Open has an amateur at the top of the leaderboard at the end of the day, the amazing Kiwi Lydia Ko, with a tournament score of -8 under par. The fifteen-year-old World number one amateur Lydia will enter the final round at the CN Canadian Women’s Open with a chance to rewrite the record books. The New Zealander holds a one-shot lead over major champions Stacy Lewis, Inbee Park, Jiyai Shin, and also Chella Choi, who is fighting for her first win, in the last round of play at Vancouver Golf Club on Sunday. Lydia was very happy to still be at the top of the board, a position way beyond her expectations coming into this event; "It's good to stay at the top of the leaderboard, but my first goal was to make the cut and hopefully top-15 or something. But to be up there is just an honor, especially playing against the world's best. Fifteen year olds don't lead at an LPGA event all the time. Like I said, I'm very surprised. But I've been playing really good golf and I've been really confident with my game. Today I tried to have more fun, but my score wasn't as good, I mean, 72 is better than 73 or any other score, so I'm pretty happy. Tomorrow, I'm just going to try my best. I've got to play my own game. I can't concentrate on what the other players are doing. If they shoot 66 and I shoot 68 and I lose, I can't control what they do." Biggest mover on the day was Stacy Lewis, she began the third round seven strokes behind Lydia and Chella. "It's the kind of course if you get some birdies early and kind of get rolling on the par 5s, you can shoot a good number, if you don't, you'll be struggling for pars. I mean, it's a course that you can play well and shoot 1 or 2 under. So it's just kind of the way the course plays, I think." Talking about being beaten by a fifteen year old Stacy admitted it was not good; "Suzann Pettersen and I were talking about it yesterday and it is kind of because we are working, this is our job, and we're working full-time on it. It's not supposed to be her job, and yet she's beating us. But I think its' good for the game. She's obviously playing well, she won an Australian LPGA event earlier in the year, and I played with her actually in Australia. She's solid. She hits it good, she putts it good, and she's rolling with the confidence. I say why not. She's playing good golf, and more power to her." Obviously everybody down here in New Zealand is rooting for Lydia, what a truly talented golfer.
