Serena Williams, of the USA, leaves the court carrying flowers and waving to fans after her defeat against Belinda Bencic, of Switzerland, during the National Bank Open tennis tournament in Toronto on Wednesday, August 10, 2022. No one knows exactly how many more matches Williams will play before walking away, and the 23-time Grand Slam champion exited the National Bank Open on Wednesday night with a 6-2, 6-4 loss to Bencic.
