No.17 seed Jelena Ostapenko shocked seventh seed American Coco Gauff 7-5, 6-3 to sail through to the quarterfinals of the Australian Open for the first time in her career on Sunday.
Ostapenko, competing in her first Round 4 at the Australian Open, leveled her career head-to-head against Gauff to 1-1 with a 93-minute triumph in Margaret Court Arena, her first over a Top 10 player at a Grand Slam in three years, and the first Grand Slam quarterfinal appearance since 2018.
"My life changed a lot (after winning 2017 Roland Garros), so I needed a few years to really get used to what happened because I was really young. I was 19 and then turned 20," Ostapenko said. "I always knew and believed in my game. If I play well, I can beat almost anyone. I was trying to work more on my consistency, especially in the preseason. Yeah, just to step on the court and play my game. I think I'm doing it quite well this week."
