TOP Malaysian golfer Gavin Kyle Green has set himself up for a strong finish after carding a confidence-boosting three-under 69 in the third round of the CIMB Classic at the TPC Kuala Lumpur.
Perez sealed his first title in nearly a year despite carding a modest three-under 69 in the final round, courtesy of a strong start with three birdies in the first four holes.
Young gun Schauffele kept in touch with two birdies in his last three holes to post a second consecutive 67, with South Korea's Kang Sung (65) a stroke further behind on 16 under.
World No. 3 Hideki Matsuyama, who was in the same group as Perez, carded a 68 and was tied for eighth after starting his round with two birdies in three holes.
Defending champion Justin Thomas' chances appear over after he finished the day tied 24th at 6 under, despite posting his best round with a 69.
"I did not think I was going to win this week. I'm still not going to work out, I'm still going to have a bad diet and I'm going to enjoy myself", Perez said after his win.
In the final round, Lahiri scored four birdies and three bogeys for a 71.
Smith, tipped pre-tournament by Ben Coley, said: "I grew up in Brisbane".
"Unreal. I think I'm the last guy that expected to win this week, to be honest with you", Perez told reporters after the win.
"I have to keep the game-plan pretty much the same really: just be smart off the tee, try to hit the fairways and then really aggressive into the greens".
Thailand's Poom, who made six of his seven birdies on the front nine, said: "I played without any expectations". I'm going to work hard and I'm just going to - I'm just taking it a day at a time, I really am.
