BUENOS AIRES, Argentina (AP) -- Argentina took an unbeatable 3-0 lead Friday in its Davis Cup quarterfinal against Kazakhstan.
The Argentine doubles team of Juan Ignacio Chela and Eduardo Schwank defeated the Kazak pair of Evgeny Korolev and Yuriy Schukin 6-3, 6-2, 7-5. Juan Monaco and Juan Martin Del Potro won their opening singles matches on Thursday.
The Kazakhs led 4-2 in the final set before Argentina rallied on the red outdoor clay at Parque Roca, on the outskirts of the Argentine capital.
The start of the five-match series was moved up a day to avoid a conflict with elections on Sunday in Buenos Aires.
Argentina, which has reached the semifinals for the seventh time in the last 10 seasons, has never won the Davis Cup. It was runner-up in 1981, 2006 and 2008.
Argentina will face either Sweden or Serbia in the semifinals.
