At the Australian Open, Madison Keys so far swept the best phase of her career by claiming her first Grand Slam title. Solidifying her place among the elite in women’s tennis, the American star overcame two-time defending champion Aryna Sabalenka in an electrifying final.

When Pegula lost Friday, she complained of slow conditions on the court. Sabalenka has noted it as well -- but not everyone feels that way.

Olga Danilovic upset Jessica Pegula in the Australian Open third round to notch her third career Top 10 win and move into the second week of a major for the second time.

Day 6 of the Australian Open saw a number of big names in men's and women's singles easily advance to the next round. But one major loss was No. 7-ranked Jessica Pegula, who was defeated in two sets by Serbian Olga Danilović.

World No. 55 Olga Danilovic produced a stunning performance at the Australian Open, defeating seventh seed Jessica Pegula in the third round on Friday. The match, which lasted 1 hour and 30 minutes, ended with a 7-6 (3), 6-1 scoreline in favor of Danilovic.

Jessica Pegula had a pretty good idea about what was to blame for her shock Australian Open loss as the world No. 6 lamented that the court was "so slow" while the balls were "so heavy." On Friday, the American tennis star saw her run at Melbourne Park come to an end after world No. 55 Olga Danilovic ousted her 7-6 (3) 6-1.

Madison Keys has been forced to pull out of next month’s ATX Open in Texas as a direct result of her winning the Australian Open. Keys sent a shiver down the spine of the tennis world when she toppled back-to-back Australian Open champion Aryna Sabalenka in last week’s Melbourne showpiece.

Pegula said before the start of the Australian Open that Keys could absolutely win it if she played her very best.

Due to an odd rule preventing more than top 10 player participating in a WTA 250 tournament, the ATX Open announced Tuesday that Keys will no longer be eligible to participate in the event. The Austin-based tournament already has No. 6 Jessica Pegula committed to play.

Four Americans - Coco Gauff, Jessica Pegula, Madison Keys, and Emma Navarro - currently occupy a top 10 spot in the WTA rankings.

Jessica Pegula has historically been a really solid performer at the Australian Open, making the quarterfinals three times in the past.

American stars Coco Gauff, Ben Shelton and Madison Keys are still in the draw at the Australian Open -- but who else is? We break it down.
