Pablo Larrazabal and Louis Oosthuizen share the lead after the first round of the Commercial Bank Qatar Masters.
The duo both shot bogey-free seven-under-par 65s at Doha Golf Club to lead by one shot.
Former Ryder Cup player Nicolas Colsaerts is one of three players in a tie for third, while there are eight men, including two-time winner Paul Lawrie, at five-under.
Defending champion Branden Grace and 2014 winner Sergio Garcia are both at two-under after opening-round 70s.
Former Open champion Oosthuizen has a habit of doing well in his first event of a calendar year, winning his first tournament in four of the last five years.
