Medvedev's defeat against Kyrgios at the US Open has caused the Russian to cease to be world number 1 on September 12. With the loss of 1,820 points by the Russian Rafa Nadal, he is already number 1 'live' in the ATP Ranking, which is officially updated on September 12.
But to keep that number 1 on September 12 and not depend on anyone, Nadal would have to reach the US Open final. Another option for the Spaniard is for Alcaraz and Ruud to lose in the semi-finals or to be eliminated earlier. Nadal, 36, has not been number 1 in the world since February 2, 2020 and plays in the round of 16 of the US Open against the American Frances Tiafoe.
In the case of Carlos Alcaraz, if Nadal prevails in the Round of 16, he should win the US Open to become the youngest No. 1 in the history of the Pepperstone ATP Rankings at 19 years old. In the event that Rafa loses against Tiafoe, it could be worth it for Alcaraz to reach the final.
Almost the same options that Casper Ruud has, he would have to win the US Open and Nadal not reach the final in order to be the new number 1 in the world. If Nadal lost in the round of 16 against Tiafoe, the Norwegian tennis player could be worth reaching the final to be number 1.
