US Open 2026: Rybakina takes WTA No.1, Djokovic drops out of ATP top 10

On September 7, 2026, the online ATP and WTA rankings were shaken as Elena Rybakina reached world No.1 for the first time while Novak Djokovic dropped out of the top 10 after a first-round loss at the US Open. Rybakina overtook Aryna Sabalenka with 8,141 points, while Sabalenka lost 1,570 points. Djokovic lost 790 points and fell six places to No.11, level on points with Frances Tiafoe but behind on the ATP tiebreak rule. Jannik Sinner remains ATP No.1 with 11,500 points despite losing 1,300 points. Alexander Zverev moved to No.2, while Carlos Alcaraz fell to No.3 after losing 1,600 points. Arthur Fils reached a career-high of No.10, and Ben Shelton rose four spots. The ranking system punishes early exits and rewards deep runs. Veterans like Djokovic face the burden of defending old points, while younger players such as Fils and Shelton gain more from each win. With the US Open still ongoing, final rankings remain uncertain. Rybakina could solidify her No.1 spot by going deeper, while Sabalenka and others can overtake her if she stumbles. The online rankings reflect results and calendar pressure, not necessarily true form. Djokovic's drop is more about point defense than ability, and the next few matches will define whether the new generation can truly displace the old guard.
