Daniil Medvedev replaces Novak Djokovic as world number one
Daniil Medvedev succeeded Novak Djokovic as world number one on Monday, becoming the first man since 2004 outside the game's "Big Four" of Djokovic, Rafael Nadal, Roger Federer and Andy Murray to occupy the top spot. US Open champion Medvedev is the third Russian man after Yevgeny Kafelnikov and Marat Safin, and 27th player overall, to rise to the top of the ATP rankings. The 26-year-old Medvedev, beaten by Nadal in the Acapulco semi-finals last week, was guaranteed to move above Djokovic after the Serb's quarter-final loss in Dubai.
