PITTSFORD, New York (AP) ― Park In-bee successfully defended her title in the LPGA Championship, beating Brittany Lincicome with a par on the first hole of a playoff Sunday to end the United States’ major streak at three.

On the playoff hole on Monroe Golf Club’s par-4 18th, Park hit her second into the rough behind the hole. Lincicome hit her approach to the left fringe, nearly identical to her position on the final hole of regulation when she made a bogey to fall in the playoff.

Lincicome chipped 6 feet past the hole and failed to convert for bogey. Park, the winner last year at Locust Hill in a playoff with Catriona Matthew, chipped to 3 feet and calmly sank her par putt for her fifth major title and fourth in the last two seasons.

Park finished with a 2-under 70 to match Lincicome at 11-under 276. Lincicome had a 71.

Americans had won the first three majors of the LPGA Tour season for the first time since 1999. Lexi Thompson began the run at Kraft Nabisco, Michelle Wie won the U.S. Women’s Open and Mo Martin the Women’s British Open.

The 26-year-old Park, from South Korea, was coming off a playoff loss to Lee Mi-rim last week in Michigan. Park also won this season in Canada and has 11 LPGA Tour victories.

She’s projected to jump from third to second in the world, passing 17-year-old Lydia Ko of New Zealand. Ko, trying to become the youngest major winner in LPGA history, shot a 70 to finish third at 8 under.

Spain’s Azahara Munoz (70) and Sweden’s Anna Nordqvist (71) tied for fourth at 6 under.

Lincicome squandered the lead she had held all day on the final hole of regulation. She hit her second shot to the left fringe and was in a good spot, but a long delay for a ruling on a shot by Suzann Pettersen only heightened the tension, and it showed.

With top-ranked Stacy Lewis among the gallery clapping, Lincicome left her first putt 8 feet short and failed to make par, forcing the playoff.

Pettersen, a two-time major winner, started the day a shot behind as she chased her first win this year. But her day went badly at the start and she shot 4-over 76. She tied for sixth at 5 under with Lewis (68), Julieta Granada (71), Shanshan Feng (72) and Lee (74).

Park’s clutch birdie putt at No. 17 put her in position to challenge and her par save at 18 was crucial. Her approach on the closing hole landed in the rough to the right of the green and she botched her shot out. Her 12-foot putt left no margin for error and the crowd roared when it rolled in. Lincicome had held the 54-hole lead at a major only once before, at the 2006 U.S. Women’s Open, but she faltered with a closing 78 and finished seventh. This time, she shook off the nerves until the end as the chance to win her second major ended in disappointment.
