The 20-time Grand Slam winner Nadal lost to Lloyd Harris in
the round of 16 in Washington to find himself dropping one place to number four
with the Greek Stefanos Tsitsipas replacing him at three.
Italian teenager Sinner, who beat the American Mackenzie
McDonald in three sets in Washington, climbs from 24th into the higher realms
of the game’s elite.
Sinner, who only turns 20 on August 16, is the youngest
player to win an ATP 500 tournament since the category was created in 2009.
By reaching the final, McDonald also enjoyed a dramatic leap
from 107th to 64th.
Novak Djokovic, who has won all three majors this year and
has his eyes firmly set on completing the sweep with another success at the US
Open, remains comfortably at number one.
The Serb has now spent a record 333 weeks in top spot, well
ahead of next-best Roger Federer, who managed 310 and is now down at number
nine.
