Serena Williams 23-time Grand Slam champion will retire from tennis after playing at the US Open later this month and ending her legendary career on the court. She has the most Grand Slam titles in the Open Era and is also the highest-earning tennis player in history with more than $94 million in career earnings. Williams wrote in Vogue: "I'm not looking for a final ceremonial moment on the pitch. I'm terrible at goodbyes, the worst thing in the world. But know that I am more grateful to you than I could ever put into words. You have guided me to so many wins and so many trophies. I will miss that version of me, that girl who played tennis. and I will miss you. #studentjournalist #sports
