OVIEDO, SPAIN: Defending champions Spain continued where they left off in 2011 with a commanding 5-0 win over Kazakhstan in the Davis Cup by BNP Paribas World Group first round. Despite missing their top two players, Rafael Nadal and David Ferrer, the Spaniards displayed their incredible strength in depth to ease past the Kazakhs and set up a home clash with Austria in the World Group quarterfinals.
