Tucked in a favourable section of the lower half of the women’s draw, No. 11-seed Bencic will face Peyton Stearns in the third round.
Asked if cracking a round of 16 milestone was on her mind, Bencic said, "I'm motivated every day. Doesn't matter if I have an opportunity or not.
"Of course it's my aim to do my best result right now. I also had a lot of years where I was injured or not in my best form coming here into Paris, so I'm really happy that this year everything is fine."
Bring on the heat
How does Bencic feel about the summery weather this week in Paris?
"For me, it's perfect," she said. "I love this right now. Because it's hot, the ball is flying more. I also like the heat. I don't like to play when it's cold and wet and windy... I feel for me it's very good when it's this hot."
Bencic certainly made the fast conditions work in her favour on Wednesday.
From 4-4 in the opening set, the Swiss turned up the heat on the 63rd-ranked American and rolled through a cluster of games in haste. Bencic was cooled off only by the ice towel that she regularly placed around her neck during changeovers.
The former Olympic gold medallist reeled off the final eight games of the match, finishing off her ninth career Roland-Garros win in style.
"I thought in the start it was a bit more tricky to get into the rhythm," she said. "I was experienced enough and maybe more smart today to win [without] playing perfect tennis."
Bencic won 14 of 17 points at net and claimed 39 of 58 of the rallies that lasted four or fewer strokes.
