Holland cuts Swiss lead to 2-1

AMSTERDAM -- Roger Federer and Stanislas Wawrinka lost to Robin Haase and Jean-Julien Rojer of the Netherlands 6-4, 6-2, 5-7, 6-3 in doubles to cut Switzerland's lead to 2-1 in the Davis Cup World Group playoff.

The Dutch pair dominated the 2008 Olympic doubles champions in the first two sets before Federer and Wawrinka rallied to take the third on the outdoor clay court.

Haase and Rojer broke Federer's serve in the seventh game of the fourth set and broke Wawrinka to seal the match.

Federer plays Haase in reverse singles on Sunday and Wawrinka takes on Thiemo de Bakker in the final match.

Czechs take 2-1 lead on Argentina

BUENOS AIRES, Argentina -- Argentina lost the Davis Cup doubles on Saturday -- falling behind 2-1 against the Czech Republic in the semifinals -- and also lost Juan Martin del Potro for Sunday's deciding singles.

Del Potro defeated Radek Stepanek on Friday in singles playing with an inflamed left wrist on his non-racket hand. He said afterward he was in pain and playing with only half of his arsenal of shots.

Del Potro's doctor warned him that his wrist was at risk if he played in the Davis Cup. Wrist problems ruled out the 2009 U.S. Open champion for most of the 2010 season.

On Saturday the risk turned to fact.

Argentina captain Martin Jaite said del Potro was being replaced by doubles player Carlos Berlocq, who will face Tomas Berdych in Sunday's first reverse singles.

"Juan Martin finished yesterday with more problems than previously thought," team doctor Miguel Khoury said. "We don't think he's in condition to play on Sunday."

Khoury said del Porto's wrist was being immobilized for 10 days.

"We think this is the best decision for his problem and the team."

Jaite learned late Friday that del Potro would not play, but said he didn't tell the team until after Saturday's doubles.

"It was not what the team expected, but we're OK and we have two more matches," Jaite said. "Obviously it's a blow to the team, but we'll continue to fight for it."

Berdych and Stepanek defeated Eduardo Schwank and Berlocq 6-3, 6-4, 6-3, and put their team on the brink of returning to the final for the first time since 2009.

Berdych will be favored to secure victory against Berlocq, who was making his cup debut. Stepanek and Juan Monaco were scheduled to meet in the last match on the outdoor clay court.

Berdych dismissed any worries about playing three days in a row.

"My physical aspect is fine," he said. "I won two tough matches, but I'm here to be ready for three days. Winning two matches gives me a lot of confidence."

Argentina is trying to reach its fifth final. It has lost a record four finals, including last year against Spain. The Czechs won as Czechoslovakia in 1980. They lost in the 2009 finals to Spain.
