Overnight joint leader Shubhankar Sharma could not play his best golf on the final day, managing only an even par round to finish Tied-10th at the $7 million CIMB Classic on Sunday.
Coming on the heels of a period during which he has had six missed cuts in nine starts, a joint lead by round three augured well for the 22-year-old from India.
However, it did not turn out be his day and he was understandably disappointed at not being able to convert his second career 54-hole lead into a maiden PGA Tour title.
The genial Australian Marc Leishman, who came close to quitting the game in 2015 when his wife was discovered with a rare life-threatening condition, continued his fine run to win his fourth title on the PGA Tour.
Leishman, playing a very high level of golf since his second round 62, carded a 7-under 65, that took his total to 26-under 262, equalling the tournament record set in 2015 by Justin Thomas.
Leishman ended five shots ahead of second placed trio — first round leader, Bronson Burgoon (68), Emiliano Grillo (66) and Chesson Hadley (66) — who finished T-2 with 21-under 267.
