ATP Doha : Montanes vs Murray Live Streaming Online

World number 10 James Blake (pictured) and Meghann Shaughnessy had been expected to get the top-seeded Americans off to a flying start in the mixed team event.

However, Dominika Cibulkova eased past Shaughnessy 6-2 6-2, while Dominik Hrbaty tamed Blake in a 6-3 4-6 7-6 tussle. The

Slovakian duo completed a 3-0 rout with a 6-4 7-6 win over Shaughnessy and Blake in the doubles.

Germany triumphed in a deciding mixed doubles tiebreaker to defeat Australia 2-1 in the other Group A clash.

The German pair of Nicolas Kiefer and Sabine Lisicki won the deciding tiebreaker 10-5 to clinch the match 6-7 6-3 7-6 after the two singles rubbers had been split.

Lisicki gave Germany the early lead when she beat Casey Dellacqua 4-6 6-2 7-5 but Australia squared the tie when Lleyton Hewitt defeated Kiefer 6-7 6-3 6-2.

Despite the loss, Hewitt said he was encouraged by his own performance in his first match since undergoing hip surgery in August.

"I've been hanging for this match for a long time...it's a great way to start the year," he said.

"It takes a lot of courage to come back from surgery and to come back and lose the first set in a tiebreak and then win the second and third convincingly - it's a good start."

Russia and France won their Group B ties at the weekend.

The winners of each group will contest Friday's final.
