Iga Swiatek is dominating her Australian Open opponents the way no one has at Melbourne Park since Maria Sharapova in 2013.

American tennis player Madison Keys seeks a fourth straight win over a seeded opponent at the Australian Open, when she takes on No. 2 Iga Swiatek in Thursday’s semifinal round.

Iga Swiatek doesn’t need any help. The women’s top seed at the Australian Open was on the right end of a missed call in her 6-1, 6-2 quarterfinal win over American Emma Navarro on Tuesday. With Navarro desperately trying to fight her way back into the match, she hit a drop shot that Swiatek scrambled to retrieve and was ruled to have done so.
