NORTH PLAINS, Ore. — Long after she earned her first trophy on the LPGA Tour, shook hands with countless tournament organizers and fielded questions from the media, rookie M.J. Hur returned to the 18th green at Pumpkin Ridge Golf Club.

There, the winner of the Safeway Classic signed autographs for about 50 fans.

The South Korean made a 6-foot birdie putt on the second playoff hole to beat Suzann Pettersen for her first tour victory.

Hur pumped her fist and broke into giggles after sinking the putt on the par-4 No. 17 hole. Then fellow tour player and best friend Haeji Kang chased the 19-year-old Hur around the green, trying to douse her with champagne.

Hur's laughter continued unabated when she was finally caught. The tears of joy didn't come until she hugged her mother.

Hur shot a final-round 65, while Pettersen and veteran Michele Redman each shot a 67 to finish at 13-under 203 and set up the playoff.

Redman, whose last tour victory came in 2000, was knocked out when she missed a short putt for par on the first playoff hole, the par-4 No. 18.

Pettersen's putt for birdie on the second playoff hole missed to the left, opening the door for Hur to clinch it.

"It was a good putt but it just didn't break, so it's disappointing," Pettersen said. "But this is what we work for, and I guess there's next week."

Pettersen had four straight birdies to surge atop the leaderboard and at one point take a three-stroke lead, but a double bogey on the par-5 No. 15 hurt her.

"I've hoisted a lot of trophies in my head," she said. "All I can do is just keep plugging along."

While ominous clouds and scattered downpours marked the first two rounds, brilliant sunshine and temperatures in the 80s welcomed the last day. Hawai'i's Michelle Wie, Ai Miyazato and Seon Hwa Lee all finished two shots back at 11-under 205.

Wie, who closed with a 66, said she's been gaining confidence, boosted by her performance in the Solheim Cup.

"It's not really pressure," she said about getting her first victory. "I just want it to happen already."

While Wie and several others were playing in the Solheim Cup, Hur was practicing. Her performance on the tour is important, she said, because her father sold his sporting goods business in South Korea to accompany her.

"I practiced a lot," she said. "That's why I had a good score this tournament."
