Serena Williams beat sister Venus in straight sets to win her seventh Australian Open and an Open‑era record 23rd Grand Slam singles title.
Serena, 35, won 6‑4 6‑4 to pass Steffi Graf in the all‑time list of major winners since the Grand Slams accepted professional players in 1968.
The American regains the number one ranking.
Serena paid tribute to her sister, who was playing her first major final for eight years, saying, that there is no way she would be at 23 without her.
