South African Branden Grace became the first player to win multiple events in the 2015 Race to Dubai after he won the Qatar Masters in Doha on Saturday.
Grace fired a bogey-free, six-under-par 66 to end the tournament on 19-under, one shot clear of Scotland's Marc Warren, and two ahead of Austrian Bernd Wiesberger.
Tied at 18-under-par as they approached the 18th tee, Grace held his nerve with a birdie, while Warren could only salvage par after his tee shot failed to find the fairway.
"It was a great day, a great week, and it's another trophy to put in the cupboard," Grace said.
"The form has been there, I played great and I managed to get in on top," Grace said. He claimed his sixth career title and second in four starts this season, followed up a first-hole birdie with 10 successive pars before going five-under through the final seven holes.
Having shot birdies on the 12th and 14th, Grace carded an eagle on the 16th after a crushing tee shot.
Grace holed the three-foot putt for birdie while Warren failed with his 20-foot effort to force a play-off.
The Race to Dubai is the European Tour's season-long competition spanning 47 tournaments.
