On her 22nd birthday, Minjee Lee notched her fourth LPGA Tour title, capturing the LPGA Volvik Championship by one shot after a 4-under-par 68 on Sunday.

Lee got off to a quick start, making three birdies in her first five holes. She made a costly bogey on the par-4 17th but bounced back with another birdie on the 72nd hole of the tournament to nail down the victory.

“I started off pretty solid, so I think I made three birdies on the front nine and I just pretty much was pretty steady until the end,” she said. “Overall I had a really solid day. I think I was striking it well and putting it pretty well.”

Lee’s approach on No. 18 got lucky as it went around a collection of trees en route to the green. But a delicate chip shot ended up close enough to the hole for a final birdie and the win.

“My drive went pretty far. I didn’t expect it to go that far. I had a 5-iron in, but I sort of had to cut it around the tree and I overcut it a little bit and I was lucky not to clip the very top end of the tree,” Lee admitted. “I had a pretty easy chip shot after that shot.”

After winning twice in 2016, Lee has since gone through a winless drought on the LPGA Tour, she won the Oates Vic Open at 13th Beach earlier this year, a European Ladies Tour and ALPG Tour event.

However, Sunday’s victory was a nice weight off her shoulders. And leading into the U.S. Women’s Open next week, she feels as confident as ever.

“I’ll go there and check out the golf course and hopefully have a good week, too,” she said.

Lee’s fourth career LPGA victory is the fourth-most among Australian players on the LPGA All-Time Winners list, behind Karrie Webb (41), Jan Stephenson (16) and Rachel Hetherington (eight).

She is the first Australian player to win in 2018 and the first since Katherine Kirk at the 2017 Thornberry Creek LPGA Classic.

Minjee Lee is an ambassador for MyGolf, Australia’s national junior introductory program to develop and promote participation in golf. A 10-week introductory program to the sport, the MyGolf program is designed for 5 to 12-year-olds and is the major driver of junior golf participation in Australia.

Both Lee and fellow MyGolf ambassador Jason Day have recorded international victories for the 2018 season.
