Japan's Naomi Osaka stunned America's Serena Williams to reach the Australian Open final on Thursday.
World no.3 Osaka smashed Serena in straight sets to win 6-3 6-4, ending the 23-time Grand Slam winner's bid for a record-equaling 24th Grand Slam title.
During the post match conference, 39-year-old Serena broke down into tears while talking to the media before walking out.
While answering a question about her future, she said: “I don't know, I'm done” and left.
It was the first time Serena lost a semi-final at the Australian Open.
Meanwhile, three-time Slam champion Osaka is enjoying a 20-match unbeaten run and she's never lost in a Slam final so the odds are stacked in her favour as she prepares to face either American Jennifer Brady or Czech Karolina Muchova in Saturday's final.
