Serena Williams lost in the third round of the U.S. Open on Friday night, likely bringing one of the most storied careers in tennis to a close. Ajla Tomljanovic defeated Williams 7-5, 6-7, 6-1 in a three set thriller to advance to the Round of 16. Williams will move on to retirement. Williams has won 23 Grand Slam singles championships in her illustrious career, the second most by a women's tennis player in the Open era. "Thank everyone that's here that's been on my side so many years, decades," Williams said through tears after the match was over.
