champion narrowly made the cut but it was another day of frustration at Oakmont.
McIlroy, 36, finished on six over but made it through thanks to a birdie on the 18th hole.

McIlroy was in danger of falling short too, and appeared as though he would let his frustrations get the better of him.
A wayward approach shot on the 12th saw the Northern Irishman fling his club in anger.
And on the 17th hole the tee box took a beating from as the five-time major winner was again unhappy with his drive.
That prompted the Sky Sports commentator to say: “Oh wow. Frustration once again boils over.
“He’s not himself right now.”;
Fans were not impressed with McIlroy’s behaviour and criticised his conduct.
One reacted saying: “Time for sanctions for this behaviour. Once per round OK but second means a one shot penalty?”;
Another added: “What happened to Rory. Sore sport lately.”;
And a third wrote: “Frustration? More like a temper tantrum.”;
