Oviedo, Spain, Feb 13: Nicolas Almagro and Marcel Granollers won Sunday's reverse singles matches to complete a 5-0 sweep for defending Davis Cup champion Spain against Kazakhstan in their first-round series.
Almagro needed just 82 minutes to beat Evgeny Korolov 6-3, 6-4 before Granollers secured a 6-3, 6-7 (2), 6-3 win over Andrey Golubev.
Both teams made changes after Spain secured the series victory in Saturday's doubles. Korolev replaced Mikhail Kukushkin while Granollers stepped in for Juan Carlos Ferrero.
Spain will host Austria in the quarterfinals on April 6-8, while Kazakhstan goes into September's playoff to keep its place in the World Group.
