Miyazato tackles Canadian Women`s Open

Winnipeg: Japan`s Ai Miyazato, fresh off a victory in Portland, Oregon, heads into the Canadian Women`s Open in Winnipeg Thursday clinging to the top spot in the world rankings of women`s golf.

Miyazato has little room for error if she wants to stay atop the rankings, with American Cristie Kerr, Suzanne Pettersen of Norway, Korean Jiyai Shin and Taiwan`s Yani Tseng in hot pursuit.Pettersen, currently ranked third, will be making her first title defence of the season after capturing her sixth LPGA title last year, when the event was held in Calgary. "If I make it, I`m really happy," Miyazato said of her chance of hanging on to number one for a second week after regaining it with her victory. "But it`s just too close in top five players. I just never know what`s going to happen after this week, but I try my best."Miyazato`s victory in Portland was her fifth of 2010, a feat she called "very surprising." The key to the win last week, she said, was keeping her emotions in check. Miyazato led after every round in the first wire-to-wire victory of her career. "If it`s high expectations ... it`s really tough to keep control of myself. So just stayed calm and tried to be myself, and it happened, so I was really happy," she said. Bureau Report
