In July 2011, Donald won his first tournament as the world number one at the Barclays Scottish Open, which was held the week before the 2011 Open Championship. He shot a bogey free −9 on Sunday to finish four strokes clear of Sweden's Fredrik Andersson Hed. The tournament however, was badly affected by heavy rain in the Inverness area, with the course becoming flooded, washing out all of Saturday's play. A decision was taken to reduce the tournament to 54 holes.
