Keys, Navarro streak into 2025 Australian Open quarterfinals

Coco Gauff, Madison Keys and Emma Navarro all carried personal streaks into the 2025 Australian Open quarterfinals. With Gauff bowing out to Paula Badosa on Tuesday, Keys and Navarro will bid to continue their runs Wednesday to set up an all-American semifinal.

Gauff entered the Melbourne quarters on a 13-match winning streak that included her WTA Finals title run and her United Cup success with the U.S. Keys brings a nine-match winning streak into the quarters that began with her Adelaide trophy run the week before the year's first major. Navarro's streak is specific to the Australian Open: She has gone the distance in all four of her Melbourne matches, winning each in three sets.

In addition to the three American women's singles quarterfinalists, Tommy Paul and Ben Shelton advanced to the last eight on the men's side. While Paul was beaten by second seed Alexander Zverev on Wednesday, Shelton will bid for his second major semifinal when he takes on Lorenzo Sonego on Thursday.

Keys seeks third AO semifinal

Keys' best Grand Slam result came when she reached the final at the 2017 US Open, but the American's first deep major run was a semifinal showing at the 2015 Australian Open. Keys also reached the final four in 2018 at Roland Garros and in 2022 at the Aussie Open, and now will bid for her fifth major semifinal appearance when she takes on 28th seed Elina Svitolina.

After beating 10th seed Danielle Collins and sixth seed Elena Rybakina, Keys faces a third seeded player in succession. Having lost just two sets this fortnight, her tightest match came in the second round, a 7-6(1), 2-6, 7-5 victory against Romania's Elena-Gabriela Ruse.

One month before her 30th birthday, Keys is winning with a re-tooled arsenal that relies on control and variety nearly as much as the power on which she has built her career.

Navarro's marathon run sets up Swiatek QF

Navarro discussed earlier this fortnight how trust in herself and her team allowed her to enter the Australian Open with a positive mindset despite an early exit in Adelaide. In Melbourne, the 23-year-old has also trusted her fitness as she's battled through four three-setters in succession.

"I love three sets! I love tennis so much I can't resist. I got to play three sets," Navarro joked after her third-round win against three-time major finalist Ons Jabeur.

Navarro backed up that result with a thrilling 6-4, 5-7, 7-5 win against ninth seed Daria Kasatkina to reach her third straight Grand Slam quarterfinal. If she is to match her semifinal run at the 2024 US Open, she will need to get past Iga Swiatek for the first time.

Their only previous meeting came in 2018 in Charleston, when both were teenagers and still finding their footing at the professional level.
