(Reuters) - Rory McIlroy believes unruly fan behaviour more common in other sports has made its way to golf courses on the PGA Tour and that spectators need to be held to a higher standard, the Northern Irishman said on Wednesday.

McIlroy, speaking ahead of this week's Tour Championship in Atlanta and a day after the PGA Tour announced an updated fan conduct policy, said there is no room for behaviour that goes against the civility and respect that are hallmarks of the game.
