The world number one and top seed, playing her first tournament since a disappointing Wimbledon campaign shadowed by a viral illness, couldn't separate herself from the eighth-seeded German in the early going.
They battled to 5-5 in the opening set, with Petkovic saving the only break point in those first 10 games, but after holding for a 6-5 lead, Williams turned the tide in the 12th, finally converting her fifth set point against Petkovic's serve.

There was no stopping the 17-time Grand Slam champion from there. After a first set lasting 50 minutes she polished off the second in 27, breaking Petkovic a fourth time when the German sent a forehand long on match point.
Williams will face third-seeded German Angelique Kerber, who beat and US veteran Varvara Lepchenko 4-6, 7-6 (7/4), 6-2.
