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 Thursday.
The world number one, playing a tournament on the Belgian's favourite clay-court 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.
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 behind Henin, 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 90 minutes.
"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.
