Nordqvist was the Swedish Junior of the Year in 2004 and '05. She played at Arizona State and was the National Golf Coaches Freshman of the Year in '07.
Paige Mackenzie, a fourth-year pro from the University of Washington, also is off to a quick start. She made three consecutive birdies after making the turn. Mackenzie tied for 13th as an amateur at the U.S. Women's Open in '05. They were both at 4-under early atop the leaderboard. Play started with a gray sky with rain chances moving to 50 percent in the afternoon.
