Australia's last standing women at the Brisbane International, Ajla Tomjlanovic is looking to grab the win against world no.8 Karolína Plíšková despite being the underdog.
The 25-year-old faces the former world No.1 at Pat Rafter Arena on Thursday night. It will be the second encounter between the two with Czech star taking bragging rights last time after a straight sets win at the Silicon Valley Classic in 2015.
The Aussie is wary of the former world no.1 but knows that she will have to focus on her game.
"There's no secret to how she plays, big serve, big groundstrokes," Tomjlanovic said.
"I'm ready for that but I just kind of want to stay within myself and take care of what I can.
"I know she will most likely execute her shots and her serves so I'll just have to hang in there and take care of myself."
The quarterfinals match is set to also test for Tomljanovic mental composure. During the off-season, she worked with a psychologist to help her prepare mentally when there are tough situations in matches.
In her match against Brit Johanna Konta on Wednesday night, Tomljanovic was broken in the second set despite leading 4-0 early on.
The negative thoughts started to creep back into her mind.
"I still have these thoughts, but I just try to stay in the moment and not worry about the next point or the next game," she said.
"My dad always tries to tell me to try to enjoy life right now because that's what you have and it's hard, but I think it's what kept me in it, and even when I was down 6-5 in the second, I still kind of believed that I could still do it."
While Tomljanovic, a self-confessed perfectionist, admits it will be tough trying to head into a match not feeling the pressure, she wants to go in fearing nothing.
"It's tricky because I always believe I can win, but at the same time I'm aware that I'm an underdog," Tomljanovic said.
"There's always a part of me that expects to win still and like pull off an upset.
"So that kind of helps my mentality, I think I will go swing freely because I know if I don't I'm going to lose."
