Serena Williams made history this morning by defeating her sister Venus 6-4, 6-4 to claim her seventh Australian Open title and 23rd overall Grand Slam title.
With her win, Serena regains her number one ranking from Angelique Kerber and surpasses Steffi Graf to become the player with the most Grand Slam titles in the Open era.
Serena also becomes the oldest woman to win a Grand Slam singles title, breaking the record she previously set in 2015 and again in 2016.
The last time Serena and Venus played each other in a Grand Slam final was in 2009 at Wimbledon. Serena would go on to win that meeting 7-6 (7-3), 6-2.
Venus, a seven-time Grand Slam champion, was playing in her first Australian Open final since 2003. That year she lost to—you guessed it—Serena.
After today’s Australian Open final, Venus had the following to say about her younger sister: “Your win has always been my win. I think you know that I’m enormously proud of you. You mean the world to me.”
Congratulations, Serena and Venus—the greatest sibling act in sports history!
