Soomin Lee went wire-to-wire at the Shenzhen International to claim his first European Tour title at Genzon Golf Club.
A weather delay on Sunday meant that the tournament needed to be completed on Monday.
Lee had five holes left and held a share of the lead when play eventually got underway an hour late due to poor visibility caused by fog on the fifth day of the tournament.
Lee went par, par, birdie, eagle, bogey to complete his fourth and final round and finish on 16-under for the tournament. That was enough to earn him victory by two shots as Joost Luiten and Brandon Stone tied for second on 14-under.
Alexander Levy, Lee Slattery and Scott Hend were a further stroke back in a tie for fourth at 13-under.
Bubba Watson's final round 66 helped secure him a top-ten finish as he tied for eighth at 10-under.
Lee has now made six starts on the European Tour. He finished in the top three on his European Tour debut at the UBS Hong Kong Open before coming into the final round of the Maybank Championship Malaysia with a three-shot lead only to make two double-bogeys in his last three holes to eventually crawl to a share of second.
With that mind, it was no surprise that Lee was visibly relieved to have finally got over the line this week.
"I got a big chance in Malaysia but I didn't make it because I was really, really nervous. Now I made it," he said
"Yesterday I was really, really nervous. We had a lot of break times and then played again so that's really good for me and I just thought about my golf and then competed until I could do it.
"First time European Tour winner in just six events. It was really incredible.
"I really, really want to play Europe so it's good for me."
The South Korean is just 22-years-old and if the start to his professional career is anything to go by, then you can expect to be hearing a lot more about him in the years to come.
