Pressel, who started the day two shots back of Pak, needed just four holes to take the lead. She overcame Pak at No. 4 when she rolled in a downhill 12-footer for birdie while Pak failed to get up and down from the left greenside bunker.
Pressel stepped to the tee first at the sixth. She pulled out a 7 iron and hit it to the front right edge of the green. "Get up! Get up!'' she yelled at the ball. It did.
The ball kicked off a large mound just off the green, took a sharp left turn and disappeared into the cup. Pressel didn't pump her fist or jump for joy, but smiled and looked for somebody to celebrate with. The first person she met was her playing partner, Pak, and the two hugged. Then Pressel embraced her caddie, Jon Yarbrough.
A large gallery roared at the tee and the volume rose as she walked onto the green. She plucked the ball out of the cup, smiled, and acknowledged the cheers.
Pressel thought maybe it was her day.
"I thought, 'Well, that's a nice time to get a lucky bounce,''' she said while holding her 5-year-old cousin on her lap. "I tried to keep hanging in there.''
Pak had every reason to be shaken, facing an 18-foot birdie putt. But she drilled it in the middle of the cup to trail by two strokes. It was a sign that she wouldn't back down.
"That was a great putt,'' Pressel said. "It was one of those things where I kind of had a feeling she was going to make it. And she did. And she kept making them.''
When Pak headed out of town to go to the airport, she was driven down the street that will bear her name for the next year - and has four other times.
