Rory McIlroy looked set for a frustrating day two at the US Open as he covered the back nine in 37, but then birdied the first, third, fifth, sixth, eighth and ninth to storm home in 30 - as far as it is possible to 'storm' in a round which took five hours, 39 minutes to complete.
McIlroy revealed he had been inspired to take a somewhat more cautious approach this week after watching the highlights of his 2014 Open victory at Royal Liverpool, which will host the year's final major again next month.
