Tennis legend Serena Williams to retire after U.S. Open in September

Serena Williams says she is ready to step away from tennis after winning 23 Grand Slam titles, turning her focus to having another child and her business interests.

She and her husband, Reddit co-founder Alexis Ohanian, have a daughter, Olympia, who turns 5 on Sept. 1.

"Believe me, I never wanted to have to choose between tennis and a family. I don't think it's fair," said Williams, who was pregnant when she won the 2017 Australian Open for her last Grand Slam trophy. "If I were a guy, I wouldn't
