Ochoa shot a 5-under 67 to move to 9 under through two rounds, three shots ahead of first-day leader Angela Park (72) and four in front of Paula Creamer (71).

The world's No. 1 player and already a two-time LPGA Tour winner this season, Ochoa took control at RiverTowne Country Club with her bogey-free round. She carded only one score higher than 4, a par on the par-5 ninth hole, and continued her stellar run with her sixth straight round of less than 70.

But with Annika Sorenstam, 1 under after a 71, not close to 100 percent and Michelle Wie's withdrawal Thursday after going 14 over for 16 holes, the friendly, polite 25-year-old star from Mexico has so far stolen the show.

ALSO FRIDAY

BOEING CHAMPIONSHIP: Tom Purtzer and Eduardo Romero took advantage of perfect scoring conditions, matching the course record with bogey-free 9-under 62s to share the first-round lead at Destin, Fla.

Jim Thorpe and Jay Haas opened with 64s in the Champions Tour's event, and nine players -- including Senior PGA Championship winner Denis Watson -- had 65s on the Sandestin Golf and Beach Resort's Raven Golf Club course.

Romero, coming off a second-place finish last week in the Senior PGA in Kiawah Island, S.C., narrowly missed a hole-in-one on the 158-yard eighth hole. His ball landed about a foot from the pin.

WALES OPEN: Denmark's Mads Vibe-Hastrup shot a 6-under 63 to take a one-stroke lead halfway through the event at Newport, Wales.

LASALLE BANK OPEN: Omar Uresti and Chez Reavie each fired 9-under 63s, but Uresti has a one-stroke lead after two rounds of the Nationwide Tour event in Glenview, Ill.

NOTE

MICKELSON HAS MRI: Phil Mickelson had an MRI exam on his left wrist Friday that showed inflammation, but no break, and the three-time major champion said he still wants to try to play next week on the PGA Tour.

Mickelson believes he injured his wrist while chipping out of the deep rough at Oakmont earlier this week.
