That win came in February 2012 in just his fifth Tour start but, due to changes to the event calendar, Huh has not had the opportunity to defend his crown until now.
In that time, the 23-year-old has claimed four top-10 finishes, including a tie for third at the Wyndham Championship in August, as he makes an impressive start to his top-level career.
And the 2012 PGA Tour Rookie of the Year is aiming to keep his cool as he defends a Tour title for the first time.
"Obviously it's been a while for me to come back here," he told a press conference.
"Normally it only takes a year to come back. Turns out I have to wait 21 months.
"So, I'm really excited and honoured to be here as defending champion and I look forward to playing good golf."
He added: "It will be the same, you know, the same as playing another tournament.
"Just give myself a good chance every single hole if possibly I can and really enjoy the moment I'm there.
"I think it's been a success on the PGA Tour. Trying to really enjoy myself on the road and inside the ropes.
"Hopefully this week will be the one week I can really enjoy. And really look forward to teeing it up on Thursday."
Huh claimed the title in 2012 in dramatic fashion as he won an eight-hole play-off against Australian Robert Allenby.
Allenby held a two-shot lead coming down the last but a double-bogey forced him into the play-off and Huh hopes there will be less drama this time around.
"Obviously last year was a little more than I expected, having an eight-hole play-off and having my first career win in my fifth start," he said.
"I'm in a little different situation. This is my pretty much third year on the PGA Tour and I think I can handle better than last year.
"So if I'm in that situation again, I would love to finish on the first hole."
Northern Ireland's Darren Clarke, Englishman Brian Davis and Spain's Alviro Quiros lead the European charge at El Camaleon but a host of Americans will fancy their chances this week.
Chris Kirk comes in off the back of his victory at the McGladrey Classic while Briny Baird, who finished second at Sea Island, has finished in the top 10 three times at this tournament.
Brian Gay won here in 2008 and comes in following a fourth-placed finish last week while major champions Angel Cabrera of Argentina, Korean Y.E. Yang, Lucas Glover and Ben Curtis are all in the field.
