MELBOURNE, Australia — Jessica Pegula knocked podcast pal and defending champion Madison Keys out of the Australian Open on Monday to secure a quarterfinal against Amanda Anisimova, another all-American match.
Their fourth-round wins on Day 9 means four Americans have reached the women's singles last eight in Australia for the first time since 2001, when Serena and Venus Williams, Jennifer Capriati, Monica Seles and Lindsay Davenport made it through.
It is also the first time the top six seeds in the women's and men's singles have all qualified for the last eight of a Grand Slam event in the Open Era.
''Sucks that one American has to go out in the quarterfinals,'' Anisimova said.
No. 6-seeded Pegula had a slightly different take: ''At least one of us will get through and I think that's great for American tennis. Yeah, it's been pretty crazy how well the women have been doing and how many top-ranked girls there are. I'm just happy to be a part of that conversation.''
Pegula and No. 4 Anisimova advanced a day after No. 3 Coco Gauff and 18-year-old Iva Jovic earned their places on the other side of the draw.
Pegula's 6-3, 6-4 win at Rod Laver Arena ended Keys' first Grand Slam title defense in a tough section of the draw.
Anisimova, runner-up at the last two majors at Wimbledon and the U.S. Open, advanced 7-6 (4), 6-4 over Wang Xinyu as the temperature started rising at Melbourne Park and organizers triggered the heat stress policy which allowed for extra cooling breaks.
