American Andy Roddick's fine run to the final of the US Open saw him jump four places in the latest ATP rankings.
The former world number one lost in the final 6-2, 4-6, 7-5, 6-1 to the current top-ranked player Roger Federer of Switzerland but that was still good enough to lift him to six in the world.
But the biggest mover was Russian Mikhail Youzhny who jumped 30 places to 24 after his semi-final showing at Flushing Meadows.
His Davis Cup team-mate Nikolay Davydenko climbed back into the top five after he also reached the last four while Scottish youngster Andy Murray rose four places to 16 after his run to the fourth round.
Federer extended his massive lead at the top of the standings to almost 2,500 points from Spanish number two Rafael Nadal, while no-one else has even half the number of points of the Swiss master.
