Netherlands upset Argentina

Qualifiers the Netherlands upset second seeds Argentina 2-1 in round robin play at the Hopman Cup yesterday.

Argentina's Gisela Dulko, who lost all four singles matches at last year's event, continued her poor run of form in the mixed team tournament with a 6-4 6-2 defeat to Michaella Krajicek.

Peter Wessels sealed victory for the Dutch, outplaying a lethargic Gaston Gaudio 6-2 7-6, before Argentina won the doubles 4-6 6-3 7-6.

Dulko made 39 unforced errors and struggled after letting the first set slip away.

Former French Open champion Gaudio made little impact against the huge Wessels serve and he was also frustrated by being foot-faulted on seven occasions.

Wessels, who fired eight aces, was better at chasing down the half-chances and deserved his first victory against a top 10 opponent in over four years.

In the other group, victory in the doubles gave Serbia & Montenegro a 2-1 win over Sweden.

Ana Ivanovic followed up Sunday's victory over American Lisa Raymond by overwhelming Sofia Arvidsson 6-3 6-1 in just 43 minutes to put Serbia & Montenegro ahead.

Thomas Johansson, who had spent the last three days in bed with a foot infection, overcame talented 18-year-old Novak Djokovic 7-6 7-6 to level the tie but Serbia took the doubles 6-4 6-2.

There was little to separate former Australian Open champion Johansson and his young opponent. The Swede saved the only break point of the first set with a big serve before claiming the tiebreak.

Djokovic led the second set 4-2 but Johansson responded by winning 12 of the next 14 points to go 5-4 up as the match progressed to a second tiebreak.
