World number one Novak Djokovic was eliminated from the ATP World Tour Finals on Friday after Tomas Berdych's victory over David Ferrer clinched the last spot in the semi-finals of the season finale at London's O2 Arena.
Djokovic would have qualified for the semi-finals if Ferrer had beaten Berdych even though the Serb had lost two of his three Group A matches.
But former Wimbledon finalist Berdych came back from a set down to defeat Ferrer and in the process brought an end to Djokovic's majestic season.
Djokovic has won the Australian Open, Wimbledon and the US Open this year, as well as five Masters titles and also replaced Rafael Nadal on top of the world rankings.
The 24-year-old - the first man to win 10 titles in a season since Roger Federer in 2006 -- finishes the year with an impressive record of 70 wins from 76 matches.
