Ukrainian qualifier Yastremska tops Azarenka to reach Australian Open quarterfinals

Qualifier Dayana Yastremska continued her fairytale run into the quarter-finals of the Australian Open in Melbourne on Monday with a 7-6(6) 6-4 upset of twice former champion and 18th seed Victoria Azarenka.

The Ukrainian world number 93, who stunned Wimbledon champion Marketa Vondrousova in the first round, had to fight hard but was rewarded for her aggression with 38 winners to forge on into a half of the draw devoid of top 10 seeds.

"I feel like my heart is going to jump out of my body," the 23-year-old said after the biggest win of her career.

"I was losing the tiebreak, I was losing the second set, I was always felt like I was running behind the train. But I think I'm a little bit of a fighter so that's why I won this match."
