Rory McIlroy leads in the US PGA Championship but three players yet to win a Major Championship got their week off to a strong start.

"I take the same mentality into every Major, which is coming in with a lot of patience," he said. "I played really well today," he said. "It's a score I would take starting the day," he said. "Haven't seen the stats but I felt like I was hitting out of the fairway most of the time. "I enjoy that challenge. "That's just not my game really. "They're just hard," he said. Still no easy task coming into the greens, but overall I felt like the course was set up pretty fair. The beauty of it is it's just never as far off as you feel. "It was a bizarre day. What is it about his game that suits the toughest tests? I didn't drive it great early and then drove it nicely at the end, but I think all six of my birdies came from the rough today, which is just very bizarre.
