Novak Djokovic Davis Cup

Novak Djokovic's Serbia opened up a 2-0 lead over Spain in Belgrade as the Davis Cup quarter-finals got under way across the globe on Friday.

Former World No 1 Djokovic made his return from the elbow injury that kept him out the recent Miami Open with a convincing 6-3, 6-4, 6-2 victory over Albert Ramos to give Serbia an early 1-0 lead in front of a rapturous home crowd.

"I’m very satisfied with my play, especially my serve," he said.

Viktor Troicki then headed out in the second singles match to give the hosts a 2-0 lead by beating Pablo Carreno Busta 6-3, 6-4, 6-3.

Spain are without their two top-ranked players, Rafael Nadal and Roberto Bautista Agut, for this tie.

Elsewhere, Australia lead USA 2-0 in their quarter-final in Brisbane after singles victories for Nick Kyrgios and Jordan Thompson.

Thompson gave the Aussies the best possible start by beating Jack Sock 6-3, 3-6, 7-6 (7-4), 6-4 in a big upset result.

Kyrgios then drove home the advantage with a hard-fought 7-5, 7-6 (7-5), 7-6 (7-5) victory over John Isner.

France lead Great Britain 2-0 in Rouen after victories for Lucas Pouille and Jeremy Chardy.

With no Andy Murray for the Brits, Kyle Edmund went down in straight sets to Pouille, while Dan Evans was also beaten in three by Chardy.

And it there was another opening-day clean sweep for Belgium in Charleroi as they took a 2-0 lead against Italy.

Belgian No 2 Steve Darcis got the ball rolling with a 6-7 (3-7), 6-1, 6-1, 7-6 (7-4) victory over Paolo Lorenzi, before David Goffin dispatched Andreas Seppi 6-4, 6-3, 6-3.
