With women’s tennis on the verge of an epic showdown between its top two players with the Australian Open title on the line, Keys, the 29-year-old American, crashed the party. She stormed back against Iga Swiatek to win their semifinal 5-7, 6-1, 7-6 (10-8)

Iga Swiatek has been slammed for ‘dirty tactics’ during Thursday’s semi-final defeat to Madison Keys at the Australian Open tennis tournament. Swiatek, seeded second in the women’s singles, was the favourite to progress but 19th-seed Keys conjured up a shock 5-7 6-1 7-6 victory.
