Rafael Nadal has slipped a place to four in the latest ATP Rankings published on Monday after losing his first semi-final on clay in 12 years in Rio.
The third spot previously occupied by the Spaniard is now filled by Andy Murray, last in action when losing in the quarter-finals in Rotterdam 10 days ago.
This is the first time Nadal has not figured in the top three since August, 2013.
Novak Djokovic, who heads the seeds at this week’s Dubai Open, retains his steely grip on the rankings ahead of Roger Federer.
Meanwhile, Australia’s Bernard Tomic has moved up another four spots to No.42 in the world after his semi-final appearance at the ATP tournament in Delray Beach, Florida.
