Tennis's newest villain, Danielle Collins, was booed and jeered by the Australian Open crowd during her third-round loss to fellow American Madison Keys on Saturday night.

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

Collins played up a hostile crowd during her win in Melbourne against home favorite Destanee Aiava.

The 20-year-old said she is a Marvel fanatic and wanted to bring a touch of superhero to the 2025 Grand Slam.
