Callaway staffer Thomas Bjorn claimed the 11th Tour title of his career just days after putting the new new Callaway Razr Hawk driver in the bag.
The Dane won the Commercial Bank Qatar Masters by four shots from fellow Callaway player Alvaro Quiros - who also had the new Razr Hawk in his bag.
Bjorn said: "I put a new driver in the bag this week, a Callaway [RAZR] Hawk which gave me 10 extra yards which you need out here."
The former Ryder Cup player was also 3rd in GIR and 5th in putts per round over the course of the week, while Quiros led the driving stats with an average drive of 323.4 yards - 19 yards longer than the closest competitor.
