Cristie Kerr did not look at the leader board, did not ask her caddie who was ahead, did not wonder about who was behind her.

Standing on the 18th green, with a chance to win the ShopRite LPGA Classic, she tried to focus on the eight-foot putt in front of her.

"I knew that I was close," Kerr said Sunday. "I said to myself, 'It doesn't mean anything unless you can execute the shot.' So that's what I did."

With playing partner Paula Creamer and Giulia Sergas sharing the lead with her at 10 under par, Kerr needed to pick up a stroke. She made the birdie putt, boosting her to 11 under and the victory.

"The putt was just an amazing, amazing under-pressure stroke that I made. I got a good read on it and it was perfect," she said.

"It's the stuff you dream about."

With Creamer, a 17-year-old amateur, in the clubhouse, all she had to worry about was Sergas, who was playing in a twosome behind her. Kerr, 26, was about to head to the practice green to prepare for a playoff when her caddie told her she had won.

The victory, which came with a $195,000 check, meant more than money.

"This was a little bit of mental breakthrough for me, this round and this tournament, because I came from behind to win. I handled the adversity well," said Kerr.

Kerr shot 66-68-68 for a three-day total of 202 to win her third LPGA title.

Creamer (69) and Sergas (71) finished one shot back at 203, followed by Juli Inkster (67) and Mi Hyun Kim (69) at 204.

Denise Killeen, who held a two-shot lead going into the final round and hoped to win her first LPGA event since joining the tour 12 years ago, shot an 8-over 79 and finished seven shots from the top.

Creamer, vying to become the first amateur to win an LPGA title since Joanne Carner in 1969, used a hot putter to shoot 7 under Saturday. She started Sunday four shots back.

But she missed birdie putt after birdie putt Sunday, including the clincher on the 508-yard 18th hole.

"I was so nervous on that putt," said Creamer, of Pleasanton, Calif. "I knew I had to make it. I think I pushed it out harder than I should have."

Cristie Kerr keeps close watch on second hole in final round on way to winning LPGA ShopRite Classic by 1 stroke over Paula Creamer, Giulia Sergas.
