Rory McIlroy falters as Brooks Koepka charges to Memphis win

Rory McIlroy lost out to world No.1 Brooks Koepka in Memphis.

(CNN)It could have been the perfect riposte to his Portrush pummeling but Rory McIlroy just couldn't hold off bulldozing Brooks Koepka in the World Golf Championships event in Memphis.

McIlroy led Koepka by a stroke going into the final round but instead of an epic duel with the world No.1 he faltered with a 71 as the American surged past with a 65 to win the WGC-FedEx St Jude Invitational by three from countryman American Webb Simpson.
The 30-year-old McIlroy, who had gone clear after a blistering 62 Saturday, ended in a tie for fourth, five strokes adrift.
