With a family wealth of over $5 billion, it's fair to say the Australian Open prize money isn't American Jessica Pegula's main motivation.

Her parents, Kim and Terry, built their fortune in oil and gas and beat the likes of Donald Trump and rocker Jon Bon Jovi to buy the NFL franchise the Buffalo Bills, while they also own NHL side the Buffalo Sabres.
But Pegula is making a name for herself at Melbourne Park, winning through to her first grand slam fourth round, and only dropping 13 games en route.
Having already accounted for the likes of major champions Victoria Azarenka, Samantha Stosur, Pegula set up a last-16 clash with world No.5 Elina Svitolina with another straight-sets win over France's Kristina Mladenovic on Saturday.
"It's the first time I've been in the fourth round so it's a new experience for me," Pegula said.
"I'm just trying to enjoy it but at the same time I still want to do well, hopefully take this as a good opportunity to keep it going the next round.
"It's definitely still new, but that's what makes it fun and exciting."
The 26-year-old is only playing in her ninth grand slam, with her early career cruelled by injury including a hip issue that required surgery and left her sidelined for 18 months.
Given her family background, her own skincare business and a charity that connects service pets with people in need, Pegula could have easily have walked away from the sport.
"The last one, my hip, was definitely the hardest, the hardest to come back from," Pegula said.
"I don't really know what happened; I think I just got over it and was like, I'm just going to fight through it again."
She said that time away from the court meant she felt younger than her actual age, although she laughed when described as the "young American".
"That does contribute to me maybe feeling younger than I am - people still think I'm young and say you're the young American but I turn 27 later this month.
"Because I was out at such pivotal times when I was younger throughout my career, I do feel like I missed, and these are all new experiences."
Pegula said she used to rail against the connection to her family name but now embraced it.
"When I was younger, it was more like I wanted to make a name for myself and then I realised as I got older, I should embrace the whole family aspect of it instead," she said.
"It was almost hurting me in a way because it wasn't going to go away and I learned to embrace that, kind of have fun with it.
"Obviously I still do like to keep things separate at times.
"Tennis is like my thing, it's my job, it's my career. It's very separate and my parents don't really have any say right now in anything I do on the court."
