Serena Williams beats Venus to win her 23rd Grand Slam title.

Serena Williams rewrote history Saturday to surpass Steffi Graf and capture a record 23rd Grand Slam title as well as the world number one ranking by beating her sister Venus in the Australian Open final.

The dominant American swept past her greatest rival 6-4, 6-4 on Rod Laver Arena for her seventh Melbourne Park crown to finally clinch the record for Open-era major titles, nearly 18 years after winning her first.

The 35-year-old, who equalled Graf’s mark of 22 at Wimbledon last year, now stands just one behind the all-time 24 won by Margaret Court, who was in the president’s box to witness Williams’ feat.
