Following the game, Williams admitted that she was a "little rusty".
"But I call this a trial run, you know".
She won four of the final five games of the second set, breaking Cirstea three times to close it out.
The same applies to Williams back on the court after having a baby, or even a Barbie doll being created in the likeness of the British boxing champion Nicola Adams (albeit one that doesn't look like it would stand up to being tickled, never mind punched). Venus did not end her boycott until the following year.
Ekaterina Makarova of Russian Federation led 10th-seeded Angelique Kerber of Germany 6-3 when their match was stopped in the opening game of the second set with Kerber holding a break point. "So it's definitely a lot easier to play later on".

On Sunday, the third round gets underway with Simona Halep, Karolina Pliskova, Jelena Ostapenko and two key matches heldover from yesterday because of the rain with Angelique Kerber down a set to Ekatarina Makarova and Sloane Stephens and Victoria Azarenka affair. But I have to play a seed regardless, sooner than later most times for the next couple of tournaments, so I have to be ready.
Who will prevail out of Serena and Venus? Bertens is a unsafe if erratic opponent, quite capable of handling Williams's power and providing plenty of her own. Bertens would rue her missed opportunities, especially after several unforced errors which saw Williams take a commanding lead.
She fell behind 3-1 early in the second set but rallied by holding serve in the fifth game.
She is not yet in prime form, not yet in prime shape, but in her first two matches she has proved she still has staying power, coming to the net effectively, something she appears to be emphasizing in this comeback, and playing the crucial points with trademark intensity. They are emotionally and psychologically fraught. But the sisters are back on tour together again, and both advanced by winning second-round matches on Saturday.
"Obviously I wish it was anybody else in the draw, literally anybody, but that's okay", she said. "It's just afterwards I don't like it as much".
