Spain's Alejandro Canizares carded a brilliant 62 to claim the lead after the first round of the Hassan Trophy in Morocco on Thursday.
Canizares shrugged off the windier conditions faced by the afternoon starters to fire 11 birdies and one bogey at Golf du Palais Royal, although that was only one ahead of England's Seve Benson.
"It was one of those days for me, my swing felt great, I started putting well and the putts went in," Canizares told Sky Sports after the lowest round of his European Tour career. "It was a lot of fun, when golf is like this it's easy.
"After today the confidence is great but it wasn't there for the last month. After Dubai I started losing a little bit of form but this game is up and down so you can't expect the best all the time.
"I think I played one of the best rounds I've played. I missed a couple of drives and from the fairway I missed one shot that cost me a bogey, but that was about it I think."
Benson, who was named after the late Seve Ballesteros, carded a flawless 63 that featured birdies at his last four holes as he looks to claim a first European Tour title in his 104th event.
"It felt pretty good to be honest," the 27-year-old from Surrey said. "It was so windy out there on the back nine pars were a good score, but I just managed to play the tough holes well and sink some putts. Capitalising on my chances is the big thing for me. I have been working really hard with my putting coach and it paid off today.”
Northern Irishman Michael Hoey is six shots off the lead in tenth place after going into the Clubhouse with a 68. Damien McGrane, meanwhile, is best of rest of the Irish after carding a 70, followed by Shane Lowry who is two shots further back; Simon Thornton shot 73 while Paul McGinley, Kevin Phelan, David Higgins and Peter Lawrie all had a poor day, each finishing four over par on 76.
The brilliant scoring from Canizares and Benson kept American Connor Arendell off the top of the leaderboard, a player who is ranked 1,511th in the world and has career earnings of exactly zero on the European Tour.
Arendell finished eighth at the qualifying school in November to earn his card for this season, but missed the cut in his first four events of 2014.
Arendell's 65 was matched by Sweden's Magnus A Carlsson, with English pair Tommy Fleetwood and Andy Sullivan and Scot Marc Warren a shot further back on six under. Defending champion Marcel Siem, who missed Wednesday's pro-am with a neck injury, returned a 69.
