After having not reached a quarterfinal since Monterrey in April, Puig has now reached the last eight or better in two of her last three events.
The Puerto Rican came out of qualifying and reached the semifinals at the Connecticut Open in New Haven prior to the US Open.
“I did a couple of these in New Haven…where I was down all the time and I would come back. I don’t want that to become a habit, but it’s always good to be on the winning side,” she added.
“There’s always an opportunity if you continue to fight. I want to fight for every point, for every game.”
With No.1 seed Aryna Sabalenka being upset by American Varvara Lepchenko in the first round, Puig and No.2 seed Petra Martic are the highest-seeded player remaining in the field this week.
The pair could be on course for a semifinal match, should Puig get past either No.5 seed Sofia Kenin or Canadian Francoise Abanda in the last eight.
“I just try to focus on each match. I can’t really afford to look ahead because if I don’t win the match that I’m scheduled to play on this day, I can’t get to the next round,” Puig said.
“For me, I prefer to take it one match at a time and focus on what I need to do right now. I have been feeling pretty good these past couple of weeks and I have been playing good tennis, so I just want to continue this progress.”
