Former world number one Ana Ivanovic needed just 72 minutes to see off Germany's Andrea Petkovic on Tuesday in the first round of Stuttgart's WTA tournament.
The 25-year-old Serbian, who won the 2008 French Open title on her way to being world number one that June, enjoyed a 6-3, 6-2 first-round win against wild-card Petkovic who is on her way back after a series of injuries.
Petkovic was playing her first match since withdrawing mid-tournament in Charleston earlier this month due to a calf injury - and that was just her third tournament back from a knee injury earlier in the year.
The only seeded player in action on Tuesday, Nadia Petrova won a tight straight-setter against Germany's match in Dinah Pfizenmaier.
The eight-seeded Russian won 7-6(7/2), 6-4 winner against the 21-year-old qualifier.
Both top seed Maria Sharapova, the reigning French Open champion, and China's Li Na, second seed here, start on Thursday having been given byes for the clay-court event which serves as a warm-up for May's French Open.
Australia's Samantha Stosur, who reached the 2010 Stuttgart final, plays former world number one Jelena Jankovic of Serbia on Wednesday, while fifth-seed Petra Kvitova of the Czech Republic is up against wild-card Annika Beck of Germany.
