The top-ranked doubles team of Bob and Mike Bryan also will return for the U.S. team, the International Tennis Federation said Tuesday. The quartet helped the U.S. win its record 32nd Davis Cup title last month against Russia.

Stefan Koubek will lead Austria, along with Jurgen Melzer, Werner Eschauer and Julian Knowle for the best-of-five series on indoor clay in Vienna on Feb. 8-10.

"The United States will bring their best players for sure, which means they show respect for our team," Austria captain Gilbert Schaller said.

Roddick is ranked No. 6 and Blake is No. 9.

Novak Djokovic, who won the Australian Open, will play in the first round for Serbia against Russia on indoor hardcourts in Moscow. The Russians will have Marat Safin back on the team, after he missed the competition with injuries last year.

Rafael Nadal, who missed both World Group matches last year because of injuries, was left off the Spain team, which will play at Peru on outdoor clay. Jo-Wilfried Tsonga, the Australian Open runner-up, will make his Davis Cup debut for France against Romania.

Koubek, the highest-ranked Austrian on the team at No. 55, and Melzer are expected to play singles, and Melzer will likely team with Knowle in doubles. Eschauer will be a substitute.

Koubek knows his team will be the underdog when the Americans come to Vienna.

"But if our team works really well and we take every chance we get, maybe we can cause an upset," Koubek said.

Knowle has struggled with injuries lately.

"I suffered from dizziness and a chronic elbow inflammation," said Knowle, who won the doubles title at the U.S. Open last year with Simon Aspelin. "I still need treatment for that, so hopefully I will be fit by next week."

The match between the United States and Austria will be the third in the Davis Cup. The Americans won the previous two, first on clay in Vienna in 1990 and hardcourts in Connecticut in 2004.
