Blake, who had lost six of his past nine matches coming into the weekend, looked dominant in beating Robredo and Lopez in straight sets. And the U.S. has had a near lock in the doubles, with Mike and Bob Bryan 11-1 in Davis Cup.

But the key for the U.S. may rest on what surface Sweden picks for the semifinal. The U.S. was ousted from the Davis Cup on clay in four of the past five years. Sweden cruised past Argentina behind singles players Thomas Johansson and Robin Soderling on carpet, and both players like fast surfaces.

"You go there, they will put you in one of these surfaces that no one knows," Sanchez said. "Maybe they play on a much faster surface than here. Maybe they choose clay because they can also play on clay. Mats Wilander is the captain, so you have to be careful."

McEnroe feels the U.S. has a shot no matter the surface.

"These guys are dedicated and really into it. I think we've got a great chance," McEnroe said. "We've got to go over there and hope after the (U.S.) Open we're all good and we're ready to take it to them in Sweden."

If the U.S. reaches the final, the Americans would play at home if it's against Russia, and on the road if Germany advances. Roddick would be there for that, too.

The three days of loud, sellout crowds led Bob Bryan to urge the U.S. Tennis Association to put the final in Winston-Salem if the U.S. hosts, although a larger arena may be needed.

At Goteborg, Sweden, the Swedes completed their victory after clinching a semifinal berth Saturday. Jonas Bjorkman of Sweden beat Sebastian Prieto 6-1, 6-2, and Juan Martin del Potro defeated Robert Lindstedt 7-6 (7), 6-4. Sweden has won the Davis Cup seven times _ twice against the U.S. (1984, 1997) _ but had not reached the semis since 2001.

At Moscow, Safin downed Paul-Henri Mathieu 7-6 (3), 6-3, 6-2 to win it for Russia. Sebastien Grosjean had tied it for France by topping Igor Andreev 7-5, 4-6, 2-6, 6-3, 6-4 in the first match. Russia won its second title last year against Argentina. France hasn't beaten Russia since 1983.

At Ostend, Germany lost twice to Belgium but will still make its first appearance in the Davis Cup semis in a dozen years. Christophe Rochus beat Michael Kohlmann 3-6, 6-4, 6-4, and Dick Norman defeated Philipp Kohlschreiber 6-2, 6-3.
