World number two Andy Roddick powered the United States into the semi-finals of the Davis Cup by defeating Sweden's Jonas Bjorkman 7-6, 6-4, 6-0 at Delray Beach, Florida on Sunday.

Roddick broke his world record serve, thumping a delivery measured at 152 mph, before closing out victory on his first match point. Mardy Fish then beat Thomas Johansson 3-6, 6-1, 6-4 to earn the U.S. a 4-1 win and a date with Belarus in the last four.

Nicolas Escude overcame stubborn resistance from Switzerland's Michel Kratochvil to book France a place in the semi-finals against Spain.

Escude, the architect of France's surprise victory over Australia in the 2001 final, was once again France's hero as he edged Kratochvil 7-6, 6-4, 7-6 in the deciding fifth rubber to snatch a 3-2 win in Lausanne.

The result avenged France's defeat by Switzerland at the same stage last year. Escude has never lost in six final rubbers.

French Open champion Juan Carlos Ferrero secured Spain's victory by fighting back from two-sets-to-one down to beat Dutchman Martin Verkerk in Palma.

DIFFICULT MATCH

"It was a difficult match with a lot of pressure and a lot of noise from the crowd. But I stayed strong and I am very proud to have got the point that won the match," said Escude.

Roger Federer had earlier kept alive Swiss hopes of reaching the semis for the second year running when he levelled the tie with a 6-2, 7-5, 6-4 win over Arnaud Clement on the hard court.

Roddick showed why U.S. captain Patrick McEnroe believes his team can claim their country's first Davis Cup since 1995.

Having already hauled the U.S. level at 1-1 after Bjorkman beat Fish in the opening singles on Friday, Roddick absorbed the Swede's best efforts early on before dismissing his experienced opponent.

He even finished with a flourish when he extended his own serving speed world record from 150 mph to 152 mph.

"Jonas came out hard but after the first set I felt comfortable," Roddick told ESPN.

"The third set was one of the best sets I've ever played."

The U.S. have won the men's team competition a record 31 times.

World Group newcomers Belarus, who knocked out 2002 champions Russia in the first round, completed Argentina's humiliation in Minsk with a 5-0 whitewash.

NOISY CONTIGENT

Spurred on by a noisy contingent of orange-clad Dutch fans, Verkerk appeared well-placed to avenge his 2003 French Open final defeat by Ferrero but he eventually ran out of steam and succumbed 6-4, 6-7, 4-6, 7-5, 6-1.

World number three Ferrero, returning to action following a bout of chicken pox, claimed victory in just over four hours to hand Spain a 3-1 lead on his favourite clay surface.

Ferrero took the opening set but lost the next two as the big-serving Verkerk found his rhythm in the converted bullring.

The Spaniard edged the fourth and then stepped up the pressure to break the Verkerk serve twice on the way to victory.

"I feel tired now.... the match against Ferrero was the toughest one I have played this weekend and it is disappointing to end it this way," said Verkerk.

"Whenever I see Ferrero I get wary because I got my ass kicked at Roland Garros by him... so he is like a nightmare for me.

"This time I wanted to show him that I can beat him and I think I did that today - the only thing I didn't do is win. But I played to the same level as him and sometimes even better."

HUMILIATING WHITEWASH

The Netherlands had staged an impressive recovery from two sets down to win the rain-delayed doubles and force the tie into a fourth rubber.

Trailing two-sets-to-one when the match was suspended due to a downpour on Saturday, the Dutch pair of Verkerk and John van Lottum claimed a 3-6, 2-6, 6-3, 6-2, 6-2 win over Spain's Tommy Robredo and Rafael Nadal.

With their top two players Guillermo Coria and David Nalbandian ruled out through injury, the weakened Argentine team floundered against Belarus on the fast carpet surface at the Football Manege arena.

The visitors managed to win only one set all weekend -- in the dead fifth rubber when Vladimir Voltchkov beat the unheralded Juan Monaco 3-6, 6-3, 6-3.
