Danny Lee has reflected on his "amazing" first PGA Tour title after winning a four-way playoff to clinch the Greenbrier Classic in West Virginia.

The New Zealander edged out American duo Robert Streb and Kevin Kisner, along with Canadian David Hearn, who forced him to a second playoff hole.

However, Lee sank a three-foot putt to par the 17th and eliminate Hearn for a maiden win on Tour - one that earns him qualification into The Open Championship and PGA Championship this summer.

"All I can say is wow," the 24-year-old told reporters.

"It's amazing just amazing. I've been so close so many times this year and to win one, wow. This is what winning feels like."

Coming into the final round, Lee, who finished on 13-under-par for the tournament, had only seven amateur victories under his belt.
