The in-form Lahiri won his fourth Asian Tour title in Indonesia last week and he will take aim at cementing his position atop the summit with another victory at the challenging Wack Wack Golf and Country Club.
He will be joined by EurAsia Cup teammates Prayad Marksaeng of Thailand, an eight-time Asian Tour winner, Siddikur Rahman of Bangladesh, Boonchu Ruangkit of Thailand and Nicholas Fung of Malaysia.
Lahiri is enjoying a hot streak after sensationally contributing two points in Team Asia's draw with Team Europe in the inaugural EurAsia Cup in Malaysia in March.
His growing confidence spilled over to the Maybank Malaysian Open where he finished in 10th place, before going on to win the CIMB Niaga Indonesian Masters when he eagled the last hole.
"It feels great to be top on the Asian Tour Order of Merit right now. One of my goals at the beginning of this year was to contend for the Order of Merit. I am glad I got off to a good start. I just have to keep focusing on playing good golf and keep getting better as the year progresses," said Lahiri.
