BERLIN, GERMANY - JUSTINE Henin took just 58 minutes to beat Chan Yung-jan of Taiwan 6-0 6-2 and reach the third round of the German Open on Wednesday.

The world number one from Belgium, playing a tournament on her favourite clay surface for the first time this year, breezed through the first set and stayed in ruthless form in the second, taking two break points out of two to seal an easy win.

'It's good to have a first match like that after not playing on this surface for a year,' Henin said at a news conference.

'With such a clear victory, keeping up the initiative and playing aggressively - I'm really pleased.'

Defending champion Ana Ivanovic had a few more problems in her first match of the tournament - the top eight seeds received a bye for the first round - before winning 7-6 6-2 against Akgul Amanmuradova of Uzbekistan.

Ivanovic, the second seed, took time to adjust to the heavy clay court at the Steffi Graf Stadium and was grateful to come through the opening set with a 7-0 victory in the tiebreak.

That emphatic scoreline seemed to encourage her, and the Serb looked a lot more fluent as she completed victory in 90min.

'Last year's success here gave me a lot of confidence - it was a turning point in my career - and I'm delighted with this win,' Ivanovic told reporters.

Fourth seeded Serb Jelena Jankovic also had a few problems early on before her class told in a 7-5 6-0 win over Peng Shuai of China.
