Rozner was tied for the lead with Guido Migliozzi, who had closed with a 65 at Education City Golf Club on Sunday, when his approach in the 18th left him far enough away that his best hope appeared to be two putts for par and a playoff.

Instead, to his astonishment, he made the double-breaking putt to finish with a two-under-par 69 for his second European Tour victory in just 29 events.

"It's unreal," Rozner said. "In my biggest dreams I couldn't imagine anything like this happening. It's probably the biggest putt of my career. Amazing."

Darren Fichardt, of South Africa, and Gaganjeet Bhullar, of India, also made birdie on the 18th that allowed them to join Migliozzi in a tie for second.

This was the final week to qualify for the WGC Match Play in two weeks in Austin, Texas, which is for the top-64 in the world rankings.

Rozner was at No.99 going into the Qatar Masters but the victory puts him into the low 60s, depending on what happens at The Players Championship.

And his spot is secure with at least two players, Tiger Woods and Adam Scott, not playing.

Fichart, the 54-hole leader, closed with a 71 while Bhullar had a 69.

Maverick Antcliff, the Queenslander who was the only Australian in the field to make the cut, ended a solid tournament on level par after his final round 71, which left him in a tie for 19th place.
