BELMONT, Michigan (AP) ― Lee Mi-rim won the Meijer LPGA Classic on Sunday for her first LPGA Tour victory, beating fellow South Korean player Park In-bee with a birdie on the second hole of a playoff.

“I (was) nervous 100 percent,” Lee said. “First time in playoff. Park Inbee is like a hero in Korea and all the young girls want to be her now in Korea.”

The long-hitting Lee drove into greenside bunker on the second extra hole ― the short par-4 17th ― and blasted out to 5 feet. After Park’s 15-foot birdie try lipped out, Lee holed her putt for the victory.

They each parred the 18th to open the playoff. Park’s approach shot hit the cup on the way past and she missed a 15-foot birdie try. Lee two-putted from 35 feet.

The 23-year-old Lee, a rookie on the LPGA Tour, closed with a 2-under 69 to match Park at 14-under 270 at Blythefield Country Club. Park, a 10-time tour winner, finished with a 70.

Lee is projected to jump to 29th in the world ranking. She earned $225,000 to jump from 40th to eighth on the money list with $414,135. Her previous best was a second-place finish in Phoenix in March.

Norway’s Suzann Pettersen was a stroke back after a 69.

Park said the win will give Lee great confidence.

“I think she was kind of, you know, thinking about whether she should come to the LPGA or whether she should stay in KLPGA,” Park said. “But I think this will definitely make her see she made a good decision.”

Park said in the end the new blade putter she put in the bag this week let her down in the last round.

“I felt I hit a good putt, but it just didn’t go in,” she said of the final birdie attempt. “The putter just wasn’t there. It was nice to shoot under par, but Mirim played well in the playoff holes.”

Pettersen, seeking her first win this year after 14 in her career, said she just didn’t hit enough good shots or drives on the back nine in the final round.

“It’s nice to get four solid rounds of competition in,” she said. “I’ve struggled this year, but it is coming. Disappointed to be one short, but it was nice to be back in contention straight after a three-week break.”

With three holes to play, Park, Pettersen and Lee were tied for the lead 14 under, but Pettersen had tree and sand troubles and made a bogey at 16 to fall a shot behind.

Park and Lee each missed birdie chances at the 17th. On the 18th, Lee two-putted for par from 40 feet, and Park made a 6-foot par putt.

Pettersen, who was playing in the group in front of Park for the day, birdied the first two holes and eagled the par-5 fifth ― hitting a 3-wood shot to 6 feet ― to tie Park at 15 under.

Lee birdied the par-5 11th to pull within a shot of Park.

After 10 consecutive pars, Park three-putted the par-3 14th for a bogey. It happened about the same time Pettersen was punching a shot from the trees to eight feet at 15 to set up a birdie and another tie.

Lee, trailing most of the day by a shot or two, then joined Park and Pettersen at 14 under with a 5-foot birdie putt at 15.

Japan’s Haru Nomura was fourth at 10-under after a 68. Germany’s Sandra Gal, the first-round leader, was another stroke back after a 66. Top-ranked Stacy Lewis had her best round of the week with a 66 to tie for 11th at 6 under.

The tournament was the first LPGA Tour event in Michigan since 2000 when the Oldsmobile Classic in East Lansing ended its nine-year run.
