McIlroy’s golfing talent is beyond question. The same could not be said of his temperament because of the weighty burden of an 11-year wait for his fifth major win.
The Masters was the biggest hurdle. He feels he should have won it in 2011 when he capitulated to a final round 80.
It is the tournament that inspired him to play the game, the one he wanted most. It is why nerves so very nearly got the better of him last Sunday.
The biggest battle was with himself. Golf is a test of nerve and that element undermines any technical gifts, no matter how grand they might be.
But somehow he clung on to deny Rose – a 44-year-old, who surely deserves another major and plays this game with commendable grace and class.
Too often golf sits in the sporting shadows, but last Sunday these two titans dragged the game into a spotlight that has rarely shone brighter.
McIlroy now sits alongside the greatest of UK sporting icons.
Sir Roger Bannister, Sir Steve Redgrave, Sir Lewis Hamilton, Sir Andy Murray, Sir Bradley Wiggins, Sir Mark Cavendish, Sir Chris Hoy, Dame Jessica Ennis-Hill, Dame Laura Kenny, Sir Jimmy Anderson – the list goes on and the order can be argued any which way.
But you can see where McIlroy might end up.
The bottom line is that in golf and in sport in general, McIlroy is right up there. Supremely talented to the extent that he could conquer vulnerabilities that had threatened an under-achiever tagline.
