Serena Williams has shown incredible empathy after her fourth round match at the Australian Open against Ukrainian teenager Dayana Yastremska because she won.

“As she was walking towards the net, I could tell she was quite upset from the absolute demolition job I served up to her,” Williams told reporters.

“That really broke my heart. I felt really sorry for her given that I’d won, otherwise I probably would have thrown a tantrum and called the umpire a thief.”

She mentioned how she had been taught “humility in victory” from her older sister, Venus.

“I remember one time in particular against Venus at Wimbledon, as I was walking to the net, I started bawling and she consoled me,” she said.

“She was fighting for women’s rights and for women’s equality and for all kinds of stuff.”
