Don't worry ... Demon's happy Open trail

While his mentor Lleyton Hewitt used to listen to 'Eye of the Tiger' to pump himself up before a match, Alex de Minaur has taken a different approach to get his mind right for an Australian Open title push.

De Minaur says he's been listening to the No.1 hit 'Don't Worry Be Happy', released by Bobby McFerrin more than 10 years before the Australian ace was even born.

He has even written the slogan on his tennis racquet bag as an additional reminder that life is pretty good for the world No.24.

'Demon' had plenty to smile about after his round one win, easily dispatching Taiwanese qualifier Hsu Yu Hsiou 6-2 6-2 6-3.

"I've got that song in my head at all times," the 23-year-old said.

"I'm listening before I step out on court, I just want that message ingrained in my head.

"Whenever there's a tough moment out there, I just kind of try to sing that song in my head and avoid any negative thoughts and try to stay positive out there."

De Minaur has brought former Australian Davis Cup player Peter Luczak in to his coaching staff, joining Adolfo Gutierrez who has coached him since he was nine.

He said that Luczak contributed to his new-found positivity.

"We started at the start of this year but I've known Peter for a long time and we've done a lot of Davis Cup matches together.

"It's been good to have him around as he's keeping a very positive mindset, keeping kind of me calm.

"I tend to be quite hard on myself, so he's kind of trying to remind me that I'm doing well, that I'm doing the right things, and to kind of enjoy every second out there."

De Minaur is the only seeded Australian in the tournament after injury to Nick Kyrgios while on the women's side, there's no defending champion Ash Barty nor drawcard Ajla Tomljanovic, who also pulled out with a knee injury.

But de Minaur, who'll face French left-hander Adrian Mannarino for a place in the last 32 on Thursday, is happy to be the standard-bearer for Australian tennis.

"I've been in this position a while, in Davis Cup obviously, and I kind of cherish it," he said.

"I know what is asked from me - I know that at times I've got some pressure on myself to deliver. I take it with pride ultimately.

"We're in the second round and there's still a long, long way to go but I try to look at it more as me individually and try to focus on my goals and get as deep as I can."

"That's the goal - get deep, enjoy myself and keep getting better every day."
