Tennis - ATP World Tour Finals
After battling in tournaments around the world for 10 months, the eight leading players in the world rankings compete for the tour title in a week-long event.
Masters tournaments had been held by the International Tennis Federation and Association of Tennis Professionals but it wasn't until the creation of the Masters Cup in 2000 that a universally recognised end of year championship was staged.
In 2009 the tournament was re-named the ATP World Tour Finals and found a new home - the O2 Arena in London.
The eight players are split into two groups of four and play round-robin three set matches to determine the semi-finalists.
