McIlroy suffers second round meltdown

A week may be a long time in politics but 20 hours can feel like a marathon for one of the game’s greatest golfers when his game goes from the sublime to the ridiculous in such a short space of time.

Late on Thursday evening, Rory McIlroy could do little wrong as he made light of a double bogey to shoot a nine under par 63 over the Muirfield Village course in Dublin, Ohio, the pride and joy of its designer and greatest supporter, Jack Nicklaus.

In a twinkle, however, the three-shot advantage he enjoyed over his nearest rivals disappeared, as the dream world of the newly-crowned BMW PGA champion suddenly turned into an ugly nightmare on the second day of the Memorial tournament.
