Serena Williams has broken down in tears and cut short her post-match news conference, after her 6-3 6-4 defeat to Naomi Osaka in the Australian Open semi-finals stalled her bid for a record-equalling 24th Grand Slam title.
Williams won her last major title at Melbourne Park in 2017, before taking a break from the sport to give birth to daughter Alexis Olympia, and has lost four major finals since returning to tennis the following year.
The 39-year-old, who is one Grand Slam title short of Margaret Court's record, walked off Rod Laver Arena to a standing ovation, pausing for a moment to put her hand on her heart and wave to the crowd.
"The Aussie crowd is so amazing, so it was nice to see," said Williams, sporting a 'Queen' necklace.
When asked if her exit from the court was a final farewell to Melbourne Park, she smiled: "If I ever say farewell, I wouldn't tell anyone."
But the smile soon faded and a question about whether her defeat to Osaka was just a "bad day at the office" saw her take a sip of water, before choking up.
"I don't know, I'm done," she said, leaving the room in tears.
Williams had looked her sharpest in years at the tournament, but 24 unforced errors cost her against Osaka, who also beat her in the 2018 US Open final.
"The difference today was errors," Williams said earlier in her news conference. "Honestly, it was opportunities where I could have won.
"I could have been up 5-love. I just made so many errors.
"Not like I was on the run or anything, they were just easy, easy mistakes. It was a big error day for me today."
Seven-time Grand Slam champion Mats Wilander says Williams' tears were due to her disappointment at the way she played and not a sign that she was making her last appearance at Melbourne Park.
"I think we see those tears because she was disappointed in the way she played," says Eurosport pundit Wilander, a three-time winner at Melbourne Park.
"For her, this is a bigger loss, because she is moving better, she is playing better and she is still not really close to Osaka, and I feel that's where the emotions start. She's probably thinking, 'what do I need to do now?'"
