May: Nadal's April form continues as he drops just 35 games en route to the French Open final, where he beats Djokovic in four sets - one of only three sets he loses in the entire clay-court season. Sharapova wins a fourth Grand Slam and her first for four years by dismantling Sara Errani, of Italy in the women's final. Murray, meanwhile, struggles with back spasms throughout and is knocked out in the quarter-finals by David Ferrer.
