Rory McIlroy left with mixed emotions

When all the social media chatter around Rory McIlroy is about the annoying frequency of his TV commercial for a watch company, you know it has not been the most impactful of weeks in America for the Irishman.

McIlroy was on US screens more often than his PGA Championship performance merited, his Script-soundtracked sales pitch as he fired a golf ball towards Dubai skyscrapers playing in every single ad break.

The song suggested he may have been standing in the hall of fame but back at Whistling Straits his play was not up to those levels, as a 17th-place finish indicated.
