However, the 22-year-old is cautious about setting goals this year.
“I am working hard to not have the mindset that I have to back anything up or defend anything that I did last year,” said Navarro.
Like Navarro, fifth seed Marie Bouzkova is also unperturbed by the big names grabbing the headlines.
“I don’t pay so much attention,” said Bouzkova. “Glad to be here and get matches under my belt.”
The Czech world No 34 produced the best performance of the day, with a crushing 6-0, 6-1 demolition of former French Open semifinalist Anisimova in just 52 minutes.
The American was clearly out of sorts after a long hiatus from the tour last year but Bouzkova was in the zone.
“I don’t think it could have been a better match for me, I served really well, went for my shots when I could,” said Bouzkova. “Obviously, Amanda has really big shots so it is not easy to be aggressive.”
French youngster Diane Parry (world No 75) also booked her place in the last eight on Wednesday, eliminating third seed Lesia Tsurenko (Ukraine, No 31) 2-6 6-4 6-1 across almost two hours.
In the first match on Wednesday, world No 71 Xiyu Wang upset compatriot and sixth seed Xinyu Wang (No 35) 6-3, 3-6, 7-6(2) in an absorbing 123-minute battle.
In doubles actio, Te Anau born Swiss player Lulu Sun continued her strong week, teaming up with Christchurch’s Jade Otway to beat the all Kiwi combination of Monique Barry and Elyse Tse 6-3 6-2 in the first round of the team event.
