I'd be interested to know what the chap had done; McIlroy pointed him out straight away.
Think he'd been heckling mcilroy when he was on his downswing.
Interesting at the prize giving when Rory mentioned he's a Yanited fan ! The booing was very very loud .
Had been heckling him all the way round apparently. There had apparently also been others singing about his ex-fiancee.
