Serena's Record 23rd Major

Serena and Venus Williams met in the final of the 2017 Australian Open, one of several Grand Slam finals the sisters have played against each other across careers that began together on public courts in Compton, California decades earlier.

Serena won 6-4, 6-4, claiming her 23rd Grand Slam singles title and surpassing Steffi Graf's Open Era record of 22, the most singles majors won by any player, man or woman, in the sport's modern era. It later emerged that Serena had been in the early stages of pregnancy during the tournament, making the achievement more remarkable still once it became public.

The all-Williams final was itself a landmark moment for the sport, two sisters from the same family occupying both places in a Grand Slam final, a rivalry-that-was-also-a-friendship that had already reshaped the landscape of women's tennis over the preceding two decades.
