Rory McIlroy speaks after his second round at Valhalla which put him in pole position to secure his fourth Major trophy.
In awful conditions at the PGA Championships, McIlroy shot a 67 to continue his superb run of form.
It was the world No1's 12th successive sub-par score and a nine-under-par halfway total of 133 means he is a combined 41-under-par for his last 10 rounds.
