She's beaten a host of credentialed opponents en route to the semi-finals. But Coco Vandeweghe is determined not to get ahead of herself even though the women's final is within sight.
Eugenie Bouchard, world No.1 Angelique Kerber and now French Open champion Garbine Muguruza have all been despatched as the unseeded American was progressively unveiled as the bolter of the Australian Open women's draw.
For Vandeweghe, a confident 25-year-old who boasts a remarkable sporting pedigree, an all-American semi-final clash against the evergreen Venus Williams awaits on Thursday.
Vandeweghe's mother was an Olympian in two sports (swimming and volleyball) and her grandfather played in the NBA. That's just for starters. But Vandeweghe says her family is always ready to bring her down a peg or two if necessary.
"If you think you're too high, you'll get put down really fast. They're good about that," Vandeweghe said after her 6-4, 6-0 win over Muguruza.
"It's a very competitive family, whether it's just playing cards around the table, or if it does end up coming to sports. But, you know, I like to think I'm smart enough not to mess with anyone in their said sport that they like to play. But not always. I did get schooled in the pool by my mom quite a few times trying to be a smart kind of individual.
"They're just my family. Nothing else, just like, regular aunts, uncles, brothers and sisters. They're quick to bring me back down off my pedestal if I get too high."
Vandeweghe raced through the second set in just 28 minutes after a hard-fought opening set against Muguruza, who had previously not lost a set this tournament.
The decisive game of the match came in the seventh game when Vandeweghe finally managed to break Muguruza's serve after numerous chances. Thereafter, Vandeweghe closed out the set in 56 minutes.
Attention has quickly turned to her clash against Williams, an opponent with a decade more experience.
Vandeweghe confirmed post-match she had at one stage sought the autograph of her countrywoman.
"She was already a great player when I asked for an autograph. Like I said out on the court, it's a dream to play someone you grew up watching. To play an unbelievable player, future Hall of Famer, Venus, to be on the court with her, I've only experienced it one time before," she said.
"To definitely have two Americans against each other in the semi-final I think is pretty cool."
Williams was similarly excited by the challenge. "What a wonderful result. It's a great win for the US to have that thought that there's going to be at least one US player in the final is great for American tennis."
