PERTH: Novak Djokovic and Ana Ivanovic led Serbia into the Hopman Cup final, winning their singles matches on Friday over Germany.

Djokovic beat Tommy Haas 6-2, 6-0, while Ivanovic lost only 15 points in defeating Tatjana Malek 6-0, 6-1.

The Serbs will face Spain in Saturday’s final.

Djokovic took a 4-0 lead in the first set but was then broken by Haas in the fifth game. The German held his serve for the only time in the match in the next game.

Haas then had three break points when trailing 2-0 in the second set but he couldn’t convert.

In mixed doubles, Haas withdrew, citing a toe injury.

In the women’s match, Ivanovic didn’t face a break point against Malek, who had been brought in to replace the injured Andrea Petkovic after the first of the round robin matches.

“Tonight I didn’t do much wrong,” Ivanovic said. Earlier, South Africa beat France 2-1 when Jo-Wilfried Tsonga had to retire in the deciding mixed doubles match with a left hamstring injury. The Frenchman was later forced to withdraw from next week’s Sydney International.

Chanelle Scheepers of South Africa beat Mathilde Johansson 4-6, 6-4, 6-4 before Tsonga defeated Kevin Anderson 7-6 (4), 7-6 (3), including winning the final five points of the first-set tiebreaker.

During the singles match, Tsonga injured his leg while stretching for a shot.

Scheepers and Anderson had won the first set of the mixed doubles 6-3 and were trailing 1-2 and on serve in the second when Tsonga indicated that he could not continue.
