Rafael Nadal's Rogers Cup win in Montreal at the weekend marked a significant step for the Spaniard as he prepares for the US Open but it wasn't enough to topple Novak Djokovic at the top of the ATP rankings, released on Monday.
Nadal, who will be vying for a fourth title at Flushing Meadows, was too strong for Daniil Medvedev in Sunday's final, seeing off the Russian 6-3 6-0 to claim his 35th Masters title.
Roger Federer and Dominic Thiem stay third and fourth respectively. Stefanos Tsitsipas, who entered the top five for the first time last week, drops two places and is leapfrogged by Kei Nishikori and Alexander Zverev.
Medvedev's reward for his appearance in Sunday's final was a one-place climb to eight.
