My selection of pictures from the last tournament of men’s professional tennis season. Eight highest-ranked players and doubles team battled for one of the most prestigious trophies of the season. This year’s robin stage saw two biggest favourites, Novak Djokovic & Roger Federer blaze to the semifinals, where they clashed with Kei Nishikori & Stanislas Wawrinka, respectively. Djokovic lost his first set at the World Tour Finals against Nishikori, but with a rather comfortable win advanced to the finals. Federer saved four match points against Wawrinka, but won in a nail-biting tie-break in the third set, only to be forced to pull out of the tournament mere minutes before the final match due to back problems. That meant Novak Djokovic became the first player to win the World Tour Finals in three consecutive years since Ivan Lendl.
