Serena Williams said that the 2022 US Open will be her final event however she left it ambiguous after losing to Tomljanovic.
She refused to officially call it quits a couple of times before the US Open despite suggesting that this would be it. She did the same after losing to Tomljanovic when a reporter asked her:
“I don't know. I'm not thinking about that. I always did love Australia, though (smiling)."
She continued by explaining that she came a long way since Wimbledon and she's just not sure whether this is really it or not:
"But yeah, you know what, I've come a long way since last year at Wimbledon. Just not sure if that was my last moment or not. Making it a different moment I think is much better. Yeah, and it takes a lot of work to get here. Clearly I'm still capable. It takes a lot more than that. I'm ready to, like, be a mom, explore a different version of Serena."
Many do expect that this will be it from Serena, especially if decides to have another child which seems in the cards. It was a fine farewell either way.
