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.
Driven by a booming serve and aggressive groundstrokes, the athletic 23-year-old battled past the Belarusian 7-6 (8-6), 6-4 at Rod Laver Arena.
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.
