NEW YORK, NY, USA – No.5 seed Simona Halep survived a gutsy upset bid from No.31 seed Timea Babos, who kept her on the ropes for much of the second half of the match before Halep scraped through, 6-1, 2-6, 6-4.

“Today I had in my head just that I can win the match, and I have just to take point by point,” Halep reflected in her post-match press conference. “So it was a good thing, and I want also to improve more in this. I feel safe when I’m on court. That’s why I refuse to lose.

“I’m stronger mentally and I don’t give up any more during the matches, even if I’m down.”

Halep looked set to cruise to a quick victory after she snapped up the first set in just 24 minutes. She made only four unforced errors to Babos’ nine, and despite the Hungarian entering the tournament ranked third on the WTA for most aces, Halep was able to contain that big serve and break three her three times.

But after being thoroughly outplayed in the opening set, Babos settled into her game and began to read Halep’s shots better. Babos suddenly began to outlast Halep at the baseline – the Romanian’s stronghold – and seemed to be one step ahead of her in the rallies.

With Babos firing off winner after winner, Halep began to play the kind of nervous, fast game that betrayed her mounting frustration. Babos rattled off six unanswered games to grab the second set and carry that momentum into the third, yanking Halep from line to line to draw out the errors and earn an early break.

The momentum shifted once as Halep refused to wilt and kept her cool to stay within touching distance. The Romanian eventually broke back at 3-3 to put them on even ground for the first time in over an hour.

After a tense couple of games, with Babos serving at 5-4, 40-15 for a chance to extend her stay in the match, the Hungarian sprayed a string of nervous errors to gift Halep match point, before surrendering the match on a double fault.

“It feels good that I could win the match,” Halep said afterwards. “It was really tough. She played unbelievable second and third set. She didn’t miss at all. She was hitting very strong, so it was a good challenge for me and it was a good match.”

“I’m really proud that I could win it and come back from 3-1 down in the third set.”

Next up for the Romanian is the No.11 seed Carla Suárez Navarro, who has been quietly making her way through the draw with her usual consistency. The Spaniard celebrated her 28th birthday with a 6-4, 6-3 victory against No.19 seed Elena Vesnina earlier in the day, and she’s yet to drop a set at the US Open.

A year ago, Suárez Navarro bowed out of the US Open in the first round, one of three first-round exits she suffered at Grand Slams. This year, she’s one of a handful of women to reach the fourth round at every Grand Slam.

“Last year in the Grand Slam I didn’t make the results,” she explained. “So I tried to be more focused, more relaxed. [Now] I play good in the Grand Slams but, you know, I want more.”

“I don’t want to lose in quarterfinals or the round before. I mean, if I’m staying in the second week I want more. I want to be in the final round.”
