LONDON — It's easy to believe the Davis Cup in the last few years has been the plaything of the Big Four in tennis.
Since 2010, Novak Djokovic, Roger Federer, and Andy Murray have won the Davis Cup for the first time. Rafael Nadal has more Davis Cup titles than all of them combined, having featured in three winning finals - the last in 2011 - and helped Spain to a fourth triumph.
The fate of the cup, especially since 2008, has usually hinged on the availability of either of the four, and this year's event looks set to be decided between Djokovic's Serbia and Murray's Britain.
