CHARLESTON, S.C. -- Jeongeun Lee6 is currently No. 1 after winning the U.S. Women's Open on Sunday, June 2, by two shots for the first win of her LPGA career.

The 23-year-old Lee6 shot a 1-under 70 in the final round at Country Club of Charleston in South Carolina to finish with a 6-under 278 total and a $1 million check, the largest ever for a women's golf championship event.

The South Korean put together two rounds of 69s and two 70s during a consistent performance.

Lee6, speaking through translator and manager Jennifer Kim, became emotional during a post-round interview with FOX.

"Throughout the year playing golf she couldn't imagine coming this far and winning her first LPGA tournament, also a major championship," Kim said Lee6 stated.

South Korea's So Yeon Ryu (final-round 70, 280 total) and Americans Angel Yin (68) and Lexi Thompson (73) tied for second.

The five-way tie for fifth included France's Celine Boutier (75, 281), who was the biggest threat to Lee6 before collapsing down the stretch.

Lee6 had four birdes and three bogeys but the two of latter occurred on 16 and 18 to give Boutier a chance.

She had an opportunity to move to 6-under on 16 but her short birdie putt lipped out. Boutier was in second place when she arrived at 18 and needed to hole a shot from the bunker to force a playoff.

But her shot wasn't close -- giving Lee6 the title -- and she went on to double-bogey the hole to finish three shots back.

"Honestly, I played so bad, I didn't even think I had a chance," Boutier said afterward. "And then on 16, when I missed a putt, I kind of knew that it was going to be hard."

At the same time, Lee6 was feeling the pressure.

"I felt pretty nervous starting on holes 16, 17 and 18 but I tried the best that I can," she said through the translator. "I know I made two bogeys but I didn't want to think about it too much. I tried the best that I can."

Lee6 has the numeral as part of her name because she is the sixth Korean golfer named Jeongeun Lee to play on the Korean LPGA Tour. Each of the other five with the name are older.

Lee6 has a fan club called "Lucky 6" and she lists her hobby as shopping. She was mostly stoic during the post-round interview but smiled when she heard "1 million dollars."

Americans Gerina Piller (68) and Jaye Marie Green (74), Japan's Mamiko Higa (74) and China's Yu Liu (75) also tied for fifth with Boutier.
