Moore is a two-time victor of this event as well, last winning in 2014.
The highest-ranked player in the field this week, Justin Thomas, follows in an eight-way tie for sixth on six under, alongside the likes of Louis Oosthuizen, Byeonghun An and European Ryder Cup star Paul Casey.
I guess the hard part will be having to leave home to compete on the PGA TOUR.
American Pat Perez returns to Malaysia to defend the title he won at the US$7 million (RM28.7 million) CIMB Classic at TPC Kuala Lumpur (TPC KL) a year ago. Coming back to Malaysia will be a good starting point, for sure. "I think I have an opportunity to play well and hopefully knock off a win or two".
Perez: As golfers, sometimes you just like a golf course the minute you set eyes on it. TPC KL is one of those golf courses where I feel comfortable standing on the tee boxes and seeing what's in front of me. The course suits my style of play and I just played beautifully. The greens are fantastic.
He also won the Malaysian Open on the same golf course in 2015, his first win on the European Tour. The fairway will be more hard because it's going to roll off the fairways because previously, it just stops or just end up a yard away. Winning the Order of Merit is something I want to achieve by December and playing well here goes a long way to achieve that.
Following a three-week break at home, Kiradech is sufficiently recharged and plans to challenge for the title against a stellar line-up which includes title holder Pat Perez, 2017 FedEx Cup champion Justin Thomas, last week's season-opening event victor Kevin Tway and World Golf Hall of Famers Ernie Els and Davis Love III.
"No doubt very, very important", said Sharma, who came to worldwide prominence with his T9 finish at the WGC-Mexico Championship where he led after the second and third rounds.
"Obviously all three events are big".
Here you can find everything you need to stay up to date with the world's foremost golf tour.
I'm looking forward to defending my title and seeing my fans there again. "They're all PGA TOUR events", said Sharma, 22. If I just play well in these three events and have consistent finishes, I'll get off to a very good start and obviously help my world ranking. I made my plans in the off-season assuming that I would play, so it came as a bit of a surprise.
He likes his chances of beating 2017 champion Pat Perez, Brandt Snedeker, Keegan Bradley and 2013 and 2014 victor Ryan Moore, who are among the starters in the CIMB field this week.
