Fox said his victory came about due to a helpful mix of skill and luck.
"I've always liked matchplay. I played a lot of matchplay as an amateur and generally played pretty well. Having not played it for about eight years, I knew at least I had some history there. I played some decent golf the whole week and it was nice to carry that into the matchplay as well," he told Jason Pine on Radio Sport.
"I had some decent luck — there were a few guys who missed putts to win holes, and I was very lucky in the first playoff — I think Jazz [Janewattananond] missed a four-footer to knock me out. It's nice to get that sort of luck and take advantage of it in the end."
Fox now prepares for next week's New Zealand Open, before taking time off for his wedding, and then playing at the Maybank Championship in Malaysia.
His next goal is to make the top 50 in the world, which ensures automatic entry into events such as the Players Championship, the Masters and the Open Championship, though Fox is aware it might take a few months to realise that objective.
"There's an opportunity to get into that top 50 if I play really well — I'd probably have to win the New Zealand Open and Malaysia — but it's not as far away as it seemed earlier in the year. I've put myself in a good place and can hopefully kick on nicely from here."
