Lee Westwood shot an opening round of 65, seven-under, to take the lead in a shortened day at the Maybank Malaysian Open.
Play was suspended at the Kuala Lumpur Golf and Country Club due to the threat of lightening with many golfers still on the course, some of which had only reached the fourth hole.
Westwood has built on a respectable seventh place finish at last week's US Masters which represented his 64th major championship without a win.
But the 40-year old took encouragement from his performance at Augusta and his confidence was on show during his first round in Kuala Lumpur.
"I played well in Houston the week before the Masters and used that momentum going into the Masters," Westwood told Sky Sports. "I played well last week in finishing seventh and I was happy to carry that on today.
"I'm pleased to get off to a good start. It's nice to have a good one and build some momentum for the week."
Westwood is looking to end his two-year wait without a title in a tournament he won in 1997 and lost in a play-off the year later.
The world number 36 began his round on the 10th where he dropped his only shot of the round with a bogey on the 539-year par five. But he birdied four of the final five holes to finish the round in style.
"I didn't make the best of starts but fortunately that didn't set the tone for the day," added Westwood. "I hit it really well and hit it close a lot.
"I had to be patient because I was hitting good putts and they weren't going in. I holed one from about eight feet on my 16th, 25 feet on the second-last hole and a nice 15-footer with a bit of curl on the last. So it was a good round of golf in tricky conditions.
"It's obviously very hot and you have to keep hydrated. The course is soft so it's playing its longest, and the greens are firm. It's testament to how good the construction of the greens are when you consider the rain we've had over the past couple of days.
"They are still releasing out, which was hard to get your head around."
Ryder Cup team-mate Nicolas Colsaerts sits just one shot behind Westwood after carding a 66 consisting of eight birdies and two bogeys. Northern Ireland's Michael Hoey is a further shot back with a 67.
South African Louis Oosthuizen, who won this event in 2012, finished on a level par 72 after two birdies were cancelled out by two bogeys.
