For a man who enjoys singing, Scottish professional Russell Knox certainly hit the high notes in 2015.
Knox broke through with his maiden PGA Tour title in spectacular fashion when he won the WGC-HSBC Champions this year.
A final round of 68 saw Knox finish two shots clear of Kevin Kisner to take the title on his debut in this tournament.
"It's incredible. I always kind of thought I was going to win a big one for some reason as my first one. I've been close a few times before. But this is going to take a long time to sink in," he said.
Born in Inverness in Scotland, Knox has spent most of his career in the United States. He played college golf at Jacksonville University and after turning professional in 2007 he focused mainly on the mini tours in America.
But it was in 2014 that Knox started to make a real impact on the PGA Tour. He finished second in the Honda Classic after losing in a playoff, and made it through to the FedExCup Playoffs to secure his place on the Tour in 2015.
Third-place finishes in both the Shriners Hospitals for Children Open and the Honda Classic as well as making 20 cuts throughout the season saw him again through to the FedExCup Playoffs, where he narrowly missed out on a place in the Tour Championship.
And then in November Knox became the first Scot to win a WGC tournament with his triumph in China.
"I always hoped it was going to happen but you're just never sure," he said of breaking through at this level of the game.
"There are just so many unbelievable players on tours all around the world and to win at this stage is a dream come true. I still can't quite believe it."
And Knox had his wife Andrea to thank for even playing in the tournament.
"I owe my wife everything for this. I had not committed to the tournament, just because I thought I had no chance of getting in the field. So I thank her very much for even committing me to the tournament. Then when I did find out the week before that I was in, my wife frantically had to fill out all the paperwork for myself and my caddie, Bradley. She was at the Chinese Embassy all day. It was extremely hectic on her behalf, and she's a superstar."
Knox now takes another step up in his career as he makes his debut in the Nedbank Golf Challenge.
And it's a career he admits he never thought would look quite like it does at this point, especially considering he didn't really shine as an amateur.
"There weren't many highlights. I think I finished third in the Scottish Under 21 Championship or something. I wasn't very good. I think I top-10ed in the Scottish Amateur Stroke Play one year at Royal Aberdeen, and that was kind of the turning point for me, because I was still playing football at the time. And when I top-10ed there, I was like, I think I can do this."
After a watershed 2015, Knox is certainly not doubting anymore.
