James Waterson reports the news from last weekend’s Davis Cup results. Rafael Nadal and Spain cruised to a 4-1 win against France, while Argentina beat Serbia in Belgrade 3-2. Nadal dominated both of his singles matches, while Novak Djokovic had to retire in the fourth rubber against Juan Martin del Potro because of a back injury he picked up during the US Open. Meanwhile, Stanislas Wawrinka beat Lleyton Hewitt in five sets to clinch Switzerland’s return to the World Group, while Kei Nishikori helped Japan re-enter the top tier for the first time since 1985. Finally, Andy Murray and Rafael Nadal have been vocal critics of the tournament schedule lately, and that dispute may come to a head when the players meet next month.
