Fearless Ukrainian qualifier Dayana Yastremska surged into her first Grand Slam quarterfinal by stunning two-time champion Victoria Azarenka at the Australian Open on Monday.

Her reward is a clash with unseeded Czech Linda Noskova, who progressed to the last eight when Ukraine's Elina Svitolina retired with a bad back while trailing 3-0 in the first set.
