US PGA Championship leader and Queenslander Jason Day believes he's ready for anything that may get thrown at him tomorrow morning on the final day of the Whistling Straits tournament.

This is the same man that battled through extreme vertigo at the US Open in June, collapsing on the course it was so bad at one stage.

Now he's just one good round away from golfing immortality - his first major title.

But he faces a stiff challenge from the two-time major champion and American wonder kid, Jordan Spieth.

Day is -15 and Spieth -13.

The Beaudesert product offered confident and upbeat answers to everything the hungry press pack threw at him after shooting a marvellous 66 today, Spieth shooting the lights out with a seven-under 65.

Spieth emerged victorious at the US Open after Day succumbed to vertigo on the final afternoon.

But it was that experience that has the Australian mentally prepared for anything as he goes about trying to win his first major.

"I wasn't out there dying, but I felt pretty awful. I was playing dizzy," Day recalled of his experience at Chambers Bay.

"And with a stationary ball, it's very hard to see the ball when you're dizzy.

"But to be able to get through that week ... and do what I did at the Canadian Open, winning that with three birdies on the final three holes ... it gave me a lot of confidence."

Day certainly wasn't seeing double with his putter in hand this morning.

His short game was fantastic, particularly over the back nine, putting calmly for birdies at the 10th, 13th, 14th and 17th, letting out some emotion on the 17th after double bogeying the 15th, and settling for par on the 16th.

He eagled the 11th, and used up just 24 putts for the round.

"I hit a lot of great drives out there and I'm very pleased with how I'm putting - every time I get on the green I get excited," Day said.

"One more day left - I've got to keep grinding."

The 27-year-old can't wait to face Spieth in the battle for the Wanamaker Trophy tomorrow morning - the two will tee off together as the final pair at 4.45am.

Again though, Day alluded to his confidence being at an all-time high, in a sign that - after overcoming vertigo on the course recently - it would take a lot to unsettle him.

"You never count out Jordan right now with how he's playing, especially this year," Day said.

"So with my confidence level and his stellar play right now, I feel like it's going to be an exciting finish."

Fellow Aussie Matt Jones is in a tie for sixth after the second-round leader faltered on the back nine, finishing with a one-over 73.

And Brisbane product Cameron Smith, 21, produced an impressive two-under round of 70, to be tied for 30th at four-under overall.

That included a double bogey on the 18th after his ball found its way near some rocks on a steep embankment.

"I drove better today and I played the best I could," he told APN.
