BEIJING, Oct. 28 (Xinhua) -- Rafael Nadal remained in first place of ATP rankings released on Monday, kicking off the final week of the regular season.

Nadal tops the ATP list with 11,670 points ahead of Serbia's Novak Djokovic (11,120) and Spaniard David Ferrer (6,600).

Nadal, Djokovic, Ferrer, Andy Murray, Juan Martin del Potro and Tomas Berdych are qualified for the next week's season-ending World Tour Finals in London.

With Murray sidelined with injury, three more places are up for grabs, currently occupied by Roger Federer, Stansilas Wawrinka and Richard Gasquet.

But Jo-Wilfried Tsonga and Milos Ranic are also still in the frame, and others including Tommy Haas also have a mathematical chance.

Federer only needs to win one more match to qualify for the 12th time, and all remaining berths will be decided at the Paris Masters which started Monday.
