The victory also wrested back the world number one ranking from Angelique Kerber who swiped it away during her winning run to the U.S. Open championship. Kerber, like a number before her, may yet be remembered as another caretaker for the ranking before its return to its rightful owner. Venus was oldest finalist in Melbourne in the professional era and won huge admiration for her unlikely run to the final. “Serena Williams, that’s my little sister, guys,” she said beaming. “Congratulations Serena on number 23, I’ve been right there with you, some of them I’ve lost with you. “Your win has always been my win, you know that. “I’m enormously proud of you, you mean the world to me.” At 35, an age at which most former champions have enjoyed life after tennis for several years, Serena’s powers appear undiminished and she will now train her sights on Margaret Court’s all-time record of 24 major titles.
