Rafa Nadal has been eliminated from the ATP World Tour tennis finals, after being outgunned by an inspired Jo-Wilfried Tsonga in an absorbing battle in London.
In what had effectively become a straight knockout match, Frenchman Tsonga claimed a memorable 7-6 4-6 6-3 victory in the final Group B tie at the season-ender to join Roger Federer in the semi-finals.
Nadal admits he has struggled to rekindle his passion for tennis in 2011.
The 25-year-old Spaniard ended 2010 as the dominant force in men's tennis after completing his career grand slam but, apart from a sixth French Open crown in June, this year has been disappointing.
He says while he's happy with how he practiced over the last three weeks he was probably a little bit more tired than usual but it's not the time for excuses.
However Nadal can still finish the year well if Spain beats Argentina in the Davis Cup final and he says after that he'll concentrate on coming back firing at the Australian Open in January.
Federer had to work hard for his 6-1 3-6 6-3 win over American Mardy Fish, who bowed out with a spirited performance despite having no chance of reaching the last four, after losing both his previous matches.
After three wins in a row Federer's semi-final opponents are either world number one Novak Djokovic, Tomas Berdych or David Ferrer.
