The Warrnambool-raised golfer, a five-time USPGA champion, is vying to win the first major of his career at The Masters this week.

Leishman, who is based at Virginia Beach on the United States' east coast, told The Standard he'd keep aiming to play about 20 events per season as he enters the peak of his career.

"I'll probably be playing about the same. With young kids, I want to be home as much as I can," he said.

"I want to play the tournaments I really like and feel like I don't have to play my absolute best to win, which is what I've been doing.

"I feel like I've got another - I'm 37 - 10 years left to play and play at a high level."

Leishman said he was exempt from exclusion on the PGA Tour for another four years.

He said his longevity as a professional golfer meant he knew the right formula to exact his best form.

"I'll probably play my 20 events a year. I'd like to spend a little bit more time back in Australia as the kids get a bit older," he said.

"I'm thinking the amount I've been playing the past couple of years is about what I'll play over the next three or four years.

"I think this is my 12^th or 13^th year on the tour and it's a matter of knowing yourself and what works for you. I feel like I'm right at what I would say is my peak right now."

Mental preparation was proving just as vital as physical preparation as Leishman readied himself for The Masters, arguably the most prestigious event in world golf.

His usual method of relaxation - tending to his lawns - is currently off limits given the grass' dormant state through the American autumn.

"(Leading into The Masters) was a matter of balancing the golf stuff with making sure that I'm fresh mentally," Leishman said.

"It's been about spending time with the kids, watching football on TV, just relaxing really. It doesn't have to be a certain activity.

"Just generally relaxing and doing something where you can just turn your brain off and just chill out. We've done that the last couple of days after putting some good work in early in the week.

"I feel like I'm ready to go. My expectations aren't as high as they normally would be, just with my form, but I think that might be a good thing. I'll go in and try to do things as well as I can.

"I need to be ready to go to Augusta to handle all the challenges it throws at us. There will be a few we won't expect but we'll be ready to handle it."

Leishman will tee off at 11:11pm Australian time on Thursday night.
