Choi, Pettersen spur each other to share of Kraft Nabisco lead

Former major winners Choi Na-yeon and Suzann Pettersen spurred each other on to a share of the lead with unheralded Briton Jodi Ewart Shadoff in the opening round of the Kraft Nabisco Championship on Thursday.

South Korean Choi and Norwegian Pettersen, playing together, fired unblemished rounds of four-under-par 68 to top a crowded leaderboard at the opening women's major of the year at the Mission Hills Country Club in Rancho Mirage, California. World number 110 Ewart Shadoff needed six birdies to offset her two bogeys and stay with her more decorated rivals, a stroke clear of South Korean Amy Yang and Swede Anna Nordqvist at three-under. World number eight Pettersen, winner of the 2007 LPGA Championship, has finished runner-up on three previous occasions at this event and was pleased with the start of her quest to go one better.
