Gulbis and the rest of the field could never string enough birdies together to make Kerr nervous.

"You never expect any player to falter," McGill said. "I was just trying to do the best that I could and if you do make some birdies and bring it on, maybe they'll start thinking twice about it."

Kerr said she was scoreboard watching, a habit she picked up from Sorenstam. What she didn't see was Sorenstam.

Sorenstam shot 69 in the morning, but remained eight shots out of the lead. Her hopes for history ended when she took six shots to reach the green on No. 7 and double bogeyed.

"Just a lot of bad shots," she said of the seventh.

Sorenstam's troubles on the greens also continued. She needed 32 fourth-round putts and had only two birdies over her final 21 holes.

"I couldn't read the greens and (caddie) Terry (McNamara) also had a difficult time," she said. "Put that together and you're not going to make a lot of putts."

And unlike last year on the second hole when Kerr double bogeyed, there were no major meltdowns.

"When she gave a shot back, she kept plugging along," Eathorne said. "She has that fire and it doesn't matter what the shot is, she has complete concentration."

Around 8 p.m., after two rounds and over 10 hours of golf, Kerr was near complete exhaustion.

"I feel," she said, "like I've reached a new level in my game."
