Rory McIlroy in flying form as he returns to happy hunting ground

McIlroy prepares for US PGA Championship at Valhalla, where he won the tournament in 2014, after back-to-back wins

In normal circumstances, Rory McIlroy returning to a scene of triumph would be cause for deep reflection. McIlroy finished in darkness at Valhalla when claiming the US PGA Championship of 2014, in what provided a theatric backdrop to his fourth and hitherto last success in one of golf's majors. McIlroy landed back in Louisville, Kentucky, this week with back-to-back PGA Tour wins to his name.

These are no ordinary times. A McIlroy media appearance on the eve of this US PGA lasted a mere nine minutes and seven questions from a packed floor. The appearance of news on Tuesday that 24 hours earlier the 35-year-old had filed for divorce from his wife of seven years has suddenly distorted the scene around McIlroy. On Sunday, McIlroy stood with trophy aloft at Quail Hollow after a dominant closing 18 holes.
