PHOENIX (AP) -- Morgan Pressel had a befitting start at Wildfire Golf Club.
She was 6 under after six holes, then 9 under through 11.
Golf's magic number of 59 - accomplished only on the LPGA Tour by Annika Sorenstam in 2001 at nearby Moon Valley - was in range and word spread quickly Thursday at the JTBC Founders Cup.
''Wow. Go Morgan,'' friend Natalie Gulbis tweeted.
''I don't know if I was necessarily thinking 59, but I probably just got a little bit excited, because I had never been that many under par in that short of a span,'' Pressel said. ''I just got a little bit quick and came back to earth.''
She did, bogeying the next two holes and closing with five pars for a 7-under 65 that left her a stroke behind first-round leader Mirim Lee.
After birdieing Nos. 1 and 2 - her 10th and 11th holes - to reach 9 under, Pressel pulled her drive left on the par-4 third. Her ball lodged at the base of a short bush, with the bulk of the branches between the right-hander and the ball. There were burrowing animal holes near the ball, but they didn't interfere with a possible swing or stance.
''I could have hit it left-handed and there were a couple of burrowing animal holes around,'' Pressel said. ''I brought them (rules officials) over to ask, but I didn't honestly think that I was going to get relief and I don't think that I deserved it.''
Pressel took an unplayable lie and missed the green to the right, chipped to 7 feet and made the putt to save bogey. She also dropped a stroke on the par-3 fourth, missing a 15-footer after hitting another iron to the right.
''It wasn't the finish that I would have hoped for, but it gives me a little bit of confidence knowing how many birdies I can make and I'm capable of,'' she said.
Pressel birdied the first four holes and made a 50-footer for eagle on the par-5 15th. She also birdied the par-3 17th and made the turn in 7-under 29.
''I don't know that I've ever gotten off to that hot of a start,'' Pressel said.
A tour regular since she was 17, the 25-year-old Pressel won the 2007 Kraft Nabisco to become the youngest women's major champion. She also won the 2008 Kapalua LPGA.
''I definitely feel like I have the ability to win again,'' Pressel said.
Lee also started on No. 10 and nearly matched Pressel's start, playing her opening nine in 6-under 30. She had three birdies and a bogey on the front side for a 64.
''Everything was good,'' said Lee, making her third LPGA Tour start.
Defending champion Stacy Lewis, top-ranked Inbee Park and Michelle Wie were two strokes back at 66 along with 2011 winner Karrie Webb, Eun-Hee Ji, Catriona Matthew, Gerina Piller and Pernilla Lindberg.
''A lot of tee shots set up well for me,'' Lewis said. ''They fit my eye.''
Coming off a victory two weeks ago in China in a Ladies European Tour event, Park birdied the final three holes. She closed with a tap-in birdie on the par-4 ninth after nearly holing a full pitching wedge.
''It was a very solid round,'' Park said. ''Very good irons.''
Wie eagled the par-5 fifth.
''I hit 3-wood, 5-iron over the green and then chipped in,'' Wie said.
Sixteen-year-old Lydia Ko had a 67. Playing alongside Park, Ko closed with a bogey after driving left into the desert.
''I forgot to bring my food and my protein bars,'' Ko said. ''That's my excuse.''
