Scotti Chefler has continued the number one globally in its amazing shape by winning four shots in the Memorial Championship in Columbus, Ohio.
The United States has shot 70 years to overcome his compatriot Ben Griffin, whose challenge faded in the back of the ninth.
After Bogeys on 12 and 13, Griffin climbed 15 and Birdy at the sixteenth to move to the Chefler strike.
But he installed it on the seventeenth to reduce the pressure on his rival, who achieved his third victory from his previous four championships.
Al -Nasr follows his victory in the PGA championship in May, which is the third Shifler victory.
He fell only one shot on his last tour when he grilled the tenth hole, but made the birds on the seventh, 11 and 15.
Shifler's victory makes him only a second player who wins the memorial in successive years, after Tiger Woods victories in 1999, 2000 and 2001.
