'All the pressure': Aussie Day OK under Masters radar

After finishing runner-up on debut in 2011, blowing a two-shot lead with three holes to play two years later and boasting three more top-five showings at Augusta National, Day has possibly his best chance yet to land an elusive green jacket.

The former world No.1 will start Sunday's final round (4.08 am Monday AEST) trailing co-leaders Cameron Young and defending champion Rory McIlroy by just three shots.

In recording just five bogeys through 54 holes, Day's "stay patient" game plan has the 38-year-old believing he can emulate 2013 champion Adam Scott and become only the second Masters winner from Australia.

Day knows if he can continue executing under the intense final-round heat that he has the experience and nous to at last get the job done in his 15th attempt

"I feel good about my game. I feel very happy with where things are," he said .

"I'm looking forward to the challenge at least. If I can get myself around the lead on the back side, I'll be very pleased.

"I feel like the guys that are leading right now have all the pressure. I'm just the chaser.

"Usually the chasers don't really have a lot of the pressure. Guys at the top of the leaderboard always are trying to defend the lead, whereas I'm pushing forward trying to cut into the lead."

Johnson applauded Day's discipline and said there was no reason the former PGA Championship winner could not bag a second major title in Georgia. 

"He's had a slew of opportunities here," Johnson said.

"So knowing Jason, knowing his team, his processes, he's got such a great demeanour, he's just got to be patient.

"I know he knows that, but it is paramount. If he gets in a streak, gets on a roll, he can climb that board quick.

"Jason's a great wedge player. He's got a really good short game in general. His putter, in particular, and his short game are his best clubs."
