Serena Williams won her seventh Australian Open singles title and reclaimed the No. 1 world ranking with a 6-4, 6-4 defeat of sister Venus William on Saturday.

Serena’s this achievement gave her a 23rd Grand Slam singles title, breaking her tie with Steffi Graf for the most in the Open era and putting her within one victory of Margaret Court’s all-time record of 24.

Williams has broken her own record, set at Wimbledon last year, by becoming the oldest woman to win a Grand Slam singles title in the Open era. Venus, 36, became the oldest finalist in Grand Slam singles in the Open era.

 “That’s my little sister, guys,” Venus said, pointing to Serena at the ceremony. She then spoke to Serena directly. “I’m enormously proud of you,” she said. “You mean the world to me.”

 “There’s no way I’d be at 23 without her,” Serena Williams said of Venus. “No way I’d be at one without her. . . . She is the only reason I’m standing here today. She’s the only reason that the Williams sisters exist.”

Later she posted a picture on instagram:

The top is never lonely when your best friend @venuswilliams is there. Here’s to #23. What a night for our family.
