Spain and Russia in last eight

David Ferrer crushed Switzerland's Stanislas Wawrinka 6-2 6-4 6-0 to fire depleted champions Spain into the quarter-finals of the Davis Cup on Sunday and set up a clash away to nine-times winners France.

Novak Djokovic booked Serbia's place in the last eight at the expense of the United States, the world number two being pushed all the way by John Isner before winning 7-5 3-6 6-3 6-7 6-4 in the fourth singles rubber in Belgrade.

Mikhail Youzhny sent Russia through when he thrashed India's Somdev Devvarman 6-2 6-1 6-3 in Moscow.

Russia, the 2006 champions will face Argentina in July's quarters, after David Nalbandian won the final rubber against Sweden's Andreas Vinciguerra 7-5 6-3 4-6 6-4 in Stockholm.

Nalbandian, recently recovered from a leg muscle tear, was a late addition to the team, and his all-court game was too much for the 232nd-ranked Vinciguerra.

Serbia face neighbours Croatia, the first meeting between the two countries since they became independent nations following the breakup of the former Yugoslavia.
