Melbourne, Australia (4E Sports) – Former top-ranked player Ana Ivanovic recorded the biggest upset in the Australian Open Sunday, stunning world No. 1 Serena Williams via a 4-6, 6-3, 6-3 win to make it to the quarterfinal round.
Heading into the match, the 14th seed Ivanovic had not won a set against Williams but that changed after she hit 33 winners against the top seed.
Williams, ailed by an injured back, had 22 winners but made 31 unforced errors as her 25-match winning streak came to an end in Melbourne.
“I actually believed,” Ivanovic said. “I had some confidence coming into today’s match. I really did certain things extremely well, and I kept her under pressure throughout the whole match, I felt.
“I definitely didn’t feel myself going into the match today,” Williams said. “I made a tremendous amount of errors, shots I missed I normally don’t miss, that I haven’t missed since the ’80s. But it’s okay. It wasn’t the best, but it was all Ana today. I thought she played really well.”
In the quarterfinal, Ivanovic will take on Eugenie Bouchard, who defeated wildcard Casey Dellacqua, 6-7(5), 6-2, 6-0.
Bouchard is the first Canadian to reach a Grand Slam quarterfinal since Patricia Hy-Boulais reached the quarterfinals of the 1992 US Open. The last Canadian to reach a Grand Slam semifinal was Carling Bassett-Seguso at the 1984 US Open.
Bouchard beat Ivanovic in their only previous meeting, a second round encounter on Centre Court at Wimbledon this past summer.
In the other fourth-round pairing, Li Na eliminated Ekaterina Makarova, 6-2, 6-0, in under an hour to move through to the quarterfinal against No.28 Flavia Pennetta.
On the men’s side, world No. 2 Novak Djokovic and Stanislas Wawrinka will once again go toe-to-toe in Melbourne after recording impressive victories Sunday.
Djokovic hammered 15th seed Fabio Fognini, 6-3, 6-0, 6-2, in 94 minutes to advance to his 19th consecutive Grand Slam quarterfinal and extend his winning streak at the Australian Open to 25 matches.
Wawrinka won the final match of the day, defeating No. 17 seed Tommy Robredo, 6-3, 7-6(3), 7-6(5). The eighth-seeded Wawrinka entered the match with just one victory in seven meetings with the Spaniard but won 55 of his 61 first serve points to move through to the last eight for the second time.
Meanwhile, world No. 3 David Ferrer produced a strong finish to defeat Germany’s Florian Mayer. 6-7(5), 7-5, 6-2, 6-1, to make it to the quarterfinal round against seventh seed Tomas Berdych, who defeated No. 19 Kevin Anderson, 6-2, 6-2, 6-3, in just under two hours.
