The others are the in-form Gaganjeet Bhullar, Anirban Lahiri - who has been here before and was T-3 in 2015 - and Rahil Gangjee, who did play on the Web.com Tour in the United States, but it is in Asia that he is making his PGA Tour debut. Here's a look at the odds to win this tournament.
Other stars competing in the event include 2014 FedExCup Champion Billy Horschel, Europe's Ryder Cup star Paul Casey, double CIMB Classic victor Ryan Moore and Brandt Snedeker, who together with Moore finished runner-up at the Safeway Open after losing to Tway in a playoff on Sunday.
Justin Thomas arrives in Malaysia this week hot off the heels of another outstanding year of golf, and aiming for a CIMB Classic hat-trick. Last year's victor, Pat Perez, is going off at 40-1 and tees off with Moore and Thomas at 8:50 p.m. ET.
Tyrell Hatton, an under-the-radar star of the European Ryder Cup team, threw away his chance of a historic three-peat at the Alfred Dunhill Links Championship - he led by four shots at one point, and Brandt Snedeker failed to capitalize on a similarly healthy lead at the Safeway Open.
Not even a year on, he's already climbed from almost 2000th in the rankings to 328th in the world, making him the fifth highest Kiwi and proud of his achievements. He has had a pretty strong run as of late, finishing in the top 3 in three of his last four events.
Q: What have you enjoyed about Malaysia in the last few years and will this year be different coming back as defending champion?
At a TPC Kuala Lumpur layout that is easy enough to handle at the best of times, with the last three winning scores being -24, -23 and -26 here, the likelihood is that the CIMB Classic will descend into a pin-seeking shootout on such soft greens. He comes into the weekend 61 in the world rankings. Moore is winless this year in 20 events with five top-10 finishes.
This proprietary computer model was also all over Ryan Moore's strong performance at the Safeway Open last week. This year, Casey has played in 20 events and he has one win with six top-10 finishes.
The event will celebrate its ninth edition this year, and is the second tournament of the new 2018-19 PGA TOUR Season.
Now that the 2018 CIMB Classic field is locked, SportsLine simulated the event 10,000 times and the results were surprising.
Apart from Shubhankar, his three other compatriot - Gaganjeet Bhullar, Rahil Gangjee and Anirban Lahiri - are also taking part in this tournament.
