Argentina and Spain made light work of their opponents in the doubles rubbers played on Saturday to enter the quarterfinals of the 2011 Davis Cup. Joining them in the last eight were seven-time champions Sweden, while 13-time winners USA along with the Czech Republic and defending champions Serbia got a step closer to the next ound. Here's a look at the doubles rubbers played on Saturday:

Sweden 3-0 Russia (Being played in Boras, Sweden):

In Boras, the veteran doubles duo of Simon Aspelin and Robert Lindstedt ensured that Sweden progressed to the quarterfinals without much hassle. Going into the match with a 2-0 lead after singles victories for Robin Soderling and Joachim Johansson yesterday, the Swedes got past the Russian pairing of Igor Kunitsyn and Dmitry Tursunov 6-4, 6-7(6), 7-6(6), 6-2 to give their team an unassailable 3-0 lead going into the final day.

India's gallant show at the Davis Cup spilled over into Saturday as the makeshift doubles pairing of Somdev Devvarman and Rohan Bopanna put on another gritty display but went down to the Serbian pair of Nenad Zimonjic and Ilija Bozoljac 6-4, 3-6, 4-6, 6-7(10).

It all started so well for the Indian pair. After a number of breaks in the opening set, the Indians broke again in the ninth game of the first set and then held serve to take the opening set 6-4 and stun the home crowd into near-silence. An encouraging start in the second set, with the Serbs facing 0-30 on their serve at 1-1 had the Indians probably dreaming of a 2 sets to love lead. It was not to be though as the Serbian duo held their serve and broke later in the set to take the set 6-3.

The opening day of the 2011 Davis Cup turned out to be a mixed one for the big guns - while traditional powerhouses France, Spain, Argentina and Sweden took 2-0 leads going into Saturday, defending champions Serbia and strong contenders Czech Republic had to settle for a 1-1 scoreline against their unfancied Asian opponents, India and Kazakhstan respectively. The United States and Croatia were also held to 1-1 draws by Chile and Germany respectively. Here's a round-up of all the action on Friday:

Sweden 2-0 Russia (Being played in Boras, Sweden):

World No.4 Robin Soderling led the way as Sweden took a 2-0 lead going into the doubles rubber on Saturday. While the Russian team was considerably weakened by the Davis Cup retirement of Mikhail Youzhny, it was a disappointing performance from the 2006 champions as they went down in straight sets in both singles rubbers. Sodering got the better of Igor Andreev 6-3, 6-3, 6-1 before comeback kid Joachim Johansson caused an upset, beating Teymuraz Gabashvili 6-3, 7-6(4), 6-4.

Somdev Devvarman proved that he belongs on the big stage of world tennis with a fabulous, straight-sets win over World No.45 Janko Tipsarevic of Serbia to level the tie at 1-1 on the opening day singles of the Davis Cup World Group Round 1 tie being played in Novi Sad, Serbia. Somdev's win was no less than what the Indians deserved on a day when their other singles player, Rohan Bopanna mounted a spirited and determined comeback only to just lose out in a tough five set contest to Victor Troicki, a player ranked more than 600 places above him in the ATP Tour Rankings!

The reigning Davis Cup champions were without world no.3 and Australian Open Champion Novak Djokovic, and leading the team in his stead was world no.18 Troicki. He square off against veteran Indian doubles specialist Rohan Bopanna in the opening encounter.
