Rory McIlroy was left undone by Muirfield Village's closing hole as he slipped from three under to an opening level-par 72 after day one of the Memorial Tournament.
McIlroy is playing in his 12th Memorial and he is yet to win one but his round on Thursday was going very smoothly up until the 18th tee. He spoke in his pre-tournament press conference about feeling particularly uncomfortable over the ball but he was 7th in Strokes Gained: Off The Tee and his all-round game was on song up until the last.
