Washington Open semi-finalist Stefanos Tsitsipas has for the first time climbed into the top five of the latest ATP rankings released Monday.
The 20-year-old Greek, who has already won tournaments in Marseille and Estoril as well as reaching the final of the Masters 1000 in Madrid, is the youngest player in the top 20.
He has leapfrogged Alexander Zverev who dropped two places to seventh.
Novak Djokovic remains at No.1, the 263rd week of his career that he has occupied the position. That is still 47 weeks short of record-holder Roger Federer (310) who stays third behind Rafael Nadal.
The biggest climber of the week is the Australian Nick Kygios who held his composure to beat Daniil Medvedev in Sunday’s Washington Open final.
The Australian rises 25 places to 27, back to where he was at the start of October and putting him within touching distance of a return to the top 20.
Aryna Sabalenka’s disappointment at losing the San Jose WTA final over the weekend may be offset to a small extent by her rise to number nine in the latest rankings.
The 21-year-old Belarusian, who was playing in her first final since winning the Shenzhen Open in China in January, was beaten in straight sets by China’s Zheng Saisai.
But the points she collected from reaching the final means she moves ahead of Serena Williams who drops to 10. Zheng was the week’s biggest mover, climbing 17 places to 38.
Roland Garros winner Ashleigh Barty is still No.1 ahead of Naomi Osaka as the players head to Montreal where a lot of points are at stake.
