Serena Williams beat her sister Venus on Saturday to claim her 23rd Grand Slam singles title in the Australian Open. The 35-year-old tennis star won 6-4 6-4 to top Steffi Graf for a Grand Slam record. The win came after an intense battle against her own sister, with whom she has played in nine Grand Slam titles throughout her career. “She's an amazing person, there's no way I would be at 23 without her,” Serena said of Venus after the win. “There's no way I would have anything without her. She's the only reason the Williams sisters exist, so thank you for inspiring me to be the best that I can be,” she said. Venus, who was the oldest finalist in Melbourne for the competition at 36, offered similar praise for Serena. “Serena Williams, that's my little sister, guys,” she said. “Your win has always been my win, you know that,” she said.
