Rafael Nadal won back-to-back matches to propel Spain to a 2-1 victory over Argentina and a place in the semifinals of the new-look Davis Cup on Friday.

World number one Nadal thrashed Diego Schwartzman 6-1, 6-2 to pull Spain level after Guido Pella put the Argentines ahead with a 6-7 (3/7), 7-6 (7/4), 6-1 win over Pablo Carreno. Nadal then teamed with Marcel Granollers to beat Maximo Gonzalez and Leonardo Mayer 6-4, 4-6, 6-3 in a must-win doubles match to see Spain into a final-four clash with Great Britain.

Britain meanwhile eased into the semis with an efficient 2-0 effort over Germany.
