Scotland's David Law equalled his lowest score on the European Tour to claim the lead after day one of the Qatar Masters.
Law carded seven birdies in a flawless 64 at Education City Golf Club to finish a shot ahead of England's Richard McEvoy, Italy's Nino Bertasio, Finland's Kalle Samooja and South Africa's Hennie Du Plessis.
“It was a good score,” said the 29-year-old, who also shot 64 in the opening round of last year’s British Masters. “I played really well. Conditions were quite easy but I was happy with my iron play and I holed some putts, which was nice.
“I’ve been guilty over the last few weeks when I’ve had decent rounds going of not finishing them off. I was semi-conscious of sticking with it and trying to go low. I was really happy with how I stuck to my routines, my processes and I came out of it with a good score.
“I’m a lot more focused on my targets rather than my golf swings. Over the last couple of seasons I’ve been guilty of asking myself why I’ve been hitting bad shots, instead of just going on to hit the next one.
"Over the break we had I sat down with my coach Alan McCloskey and Paul Lawrie, we discussed it and it's all about getting the ball in the hole now, trusting that you've done the hard work and the work's done."
Defending champion Jorge Campillo, who defeated Scotland's David Drysdale in a playoff last year, was part of an 11-strong group on four under par, with Drysdale returning a one-under-par 70.
Former champion Eddie Pepperell, who won the title in 2018 but was disqualified last year, birdied his first four holes before having to settle for a 69 to lie five shots off the lead.
Northern Ireland's Cormac Sharvin posted a one-under 70, while Paul Dunne (74) and Jonathan Caldwell (75) have their work cut out to make the weekend cut after their opening rounds.
On a day of low scoring, 74 players broke par and the final group of Darren Fichardt, Gonzalo Fernandez-Castano and Sebastian Heisele were three, two and one under respectively with one hole to complete on Friday morning.
British and Irish unless stated, par 71, (a) denotes amateurs. Play suspended due to darkness with one group left to finish the round
