Second Major Title of Year for Inbee Park Inbee Park of South Korea after defeating Catriona Matthew in a playoff. PITTSFORD, N.Y. - Inbee Park of South Korea nearly gave it away Sunday, but she held on at the Wegmans L.P.G.A. Championship to earn her fourth victory and second major title of the season. Park, 24, the world's top-ranked player, held a three-shot lead with five holes to play in regulation but watched that cushion disappear with bogeys on three of the holes after errant shots into the rough. Park bogeyed No. 18 to finish at three-over-par 75 and drop into a tie with Catriona Matthew of Scotland, who carded a bogey-free round of four-under 68. Matthew stormed from seven shots back to catch Park for a sudden-death showdown at Locust Hill Country Club. Park edged Matthew with a 20-foot birdie putt on 18 on the third extra hole; the two were tied at five-under 283 before the playoff. "It feels good to win because I hit the ball everywhere and it made the day so much tougher," said Park, who became one of six L.P.G.A. players to win the first two majors of a season. I struggled, and it's almost a miracle that I won. Park carded rounds of 72, 68, 68 and 75 on a course that had been saturated by nearly five inches of rain, forcing marshals to mark shots into the thick rough with tiny flags. Suzann Pettersen of Norway blistered the course with a seven-under 65 to move into a tie for third with Morgan Pressel at four-under 284. Pettersen birdied 5 of her last 11 holes and 3 of her last 6. The South Koreans Amy Yang (70), Chella Choi (72), Sun Young Yoo (73) and Jiyai Shin (75) tied for fifth at three-under. For most of the final round, it was a two-player race between Park and Pressel, but Pressel, who led the tournament after two rounds, also struggled with errant shots and putts that would not fall. She had three bogeys on the back nine and dropped out of the lead. "I'm definitely disappointed, but it's the first time in a long time I've contended, so I'm happy with the way that I played this week as a whole," said Pressel, who has not won since 2008 and has only one top-10 finish this year. Normally one of the tour's most accurate players, Park struggled to stay in the fairway in the final round and scrambled more than once to recover from the deep grass. She hit only 6 of 14 fairways and found 8 of 18 greens in regulation Sunday. But in the playoff, Park hit all three fairways. "I just wasn't comfortable with my swing in the final round," she said. I don't know if my swing was bad or my body was tired on the back nine, but I was happy I made the playoff. The stress of Locust Hill's unforgiving rough in a major championship was compounded by the fact that Park was one of 77 players who played 36 regulation holes Sunday in the rain-plagued event. Thursday's opening round was pushed back a day because of heavy rain, so the third round started Sunday at 6:30 a.m., with only 20 minutes between the conclusion of the third and the start of the final round at noon. "I feel like I ran a marathon today," Park said. This golf course was playing tough and I'm happy I got it done. The victory was Park's seventh and her third in a major championship. She also won the 2008 United States Women's Open and this year's Kraft Nabisco Championship. In 11 starts this year, she has won four tournaments, posted two other top-10 finishes and earned more than $1.2 million in prize money. And since her 2012 visit to this event, Park has jumped from No. 26 to No. 1 in the world rankings. "She's had an amazing run for the last two years," said Matthew, 43, who had no idea she was in contention until she reached the 18th green. She's just so consistent and really doesn't hit many bad shots. A mother of two, Matthew was hoping for a chance to win her fifth L.P.G.A. title and second major. "The big tournaments are the ones you want to win," she said. And for Park, that chance finally came after 39 holes Sunday.
