Benson won national amateur championships in Qatar and Russia before deciding to turn professional in 2007. He also played in a European Tour event in each country while still an amateur. He finished 10th in the 2006 Russian Open and 58th in the 2007 Qatar Masters. He was not able to make the 72-hole cut at the 2007 European Tour Qualifying School but earned a spot on the Challenge Tour for 2008 because he had reached the final stage.
Making it to the European Tour
In 2008, Benson won his first professional tournament, taking the Wensum Valley International Open on the PGA EuroPro Tour. He won two Challenge Tour events later in the year, setting a course record with a 62 in the third round on the way to winning the Piemonte Open. Benson's other 2008 win came in the Ypsilon Golf Challenge by Alex Cejka, where he defeated two other players in a three-hole playoff. These performances helped Benson finish sixth on the Challenge Tour's money list and gain full-time status on the European Tour.
