The American managed only three birdies, offset by a bogey on the 16th hole, to sign for a two-under-par 68 and finish at 15-under, two shots ahead of his compatriot Tony Finau and Englishman Justin Rose who tied for second place. Finau had closed the gap with three consecutive birdies on the back nine before bogeys on the 16th and 17th set him back, giving Johnson his ninth European Tour title.
