PITTSFORD, N.Y. — Inbee Park birdied the third hole of a sudden-death playoff with Catriona Matthew to win the rain-delayed LPGA Championship on Sunday.

Park made a 20-foot putt on the par-4 18th to go 2-for-2 in LPGA Tour majors this season. She rebounded in the playoff after blowing a three-shot lead with a closing 3-over 75. The top-ranked South Korean star bogeyed three of her final five holes in regulation and hit only six fairways in the final round.

“It feels great. It was a tough day out there,” Park said. “The amount of fairways I was missing today, it’s almost a miracle that I won today. I think I got a little lucky there, too. And I really tried to fight off and tried not to give up. That really paid off.”

The 42-year-old Matthew, from Scotland, shot a bogey-free 68 to match Park at 5-under 283 at Locust Hill.

It was a dramatic finish to a marathon of a day in which organizers were forced to squeeze in the final two rounds after torrential rain postponed the first round Thursday.

And a 36-hole day ended up going 39. The tournament wasn’t decided until nearly 8 p.m., local time some 12 hours after Matthew teed off to open her third round.

After both made par on the first two playoff holes, Matthew struggled off the 18th tee on the third. After having difficulty advancing the ball out of the rough just below the green on her third shot, Matthew missed a 50-foot par chip.

The 24-year-old Park also won the Kraft Nabisco in California in early April and has four victories this year. With the victory, Asian players have won nine straight majors.

Also the 2008 U.S. Women’s Open winner, Park became only the seventh player to win the LPGA’s first two majors in a season, and the first since Annika Sorenstam won the same two events in 2005.

Park has seven career LPGA Tour victories, six in her past 22 starts.
