Gavrilova fell to former world No.1 Victoria Azarenka 6-1 6-2 and it ended a year of frustrating performances at Grand Slams. 

It was the first time since 2015 that Gavrilova had not made it to the fourth round at any major. However, she had her best performances at both the French Open and Wimbledon in her career to date, managing to reach the third round.

She expressed her disappointment at her performance earlier this morning AEST against Azarenka with just 14 winners to 27 unforced errors.

“I just didn’t execute today,” she told AAP.

“I was just making way too many errors with my forehand. My serving percentage was pretty poor too, so it puts me under a lot of pressure.”

However, another hot and humid day in New York left Gavrilova feeling even more frustrated.

“It doesn’t help when you’re losing and it’s hot as well so you have to fight the heat and the opponent and your emotions because you’re not playing as well as you want to,” she said.

Meanwhile, Barty overcame 2015 French Open finalist Lucie Safarova 7-3 6-3 to reach the third round. However, it came under bizzare circumstances with a mid-match stoppage after a malfunction with the on-court PA system.

Play was halted as a strange and annoying sound came from the PA system which came after Barty was trying to close out a set at 5-3. The players could barely hear the umpire trying to explain the hold-up.

“It was very strange. I don’t think Lucie and I have ever come across anything like that before,” Barty said.

“(The referee) came out and told us that they called the sound guys and they had no idea what it was or didn’t know how to fix it.

“So we were hoping it didn’t go on for too long,” she said.

Barty had no problem dealing with it through and neither did her opponent but it did see Safarova draw level at 5-5 however, it was one-way traffic after that.

The highest ranked Aussie blasted 10 aces and won 86 percent of points after landing her first serve. 

She will either face Garbine Muguruza or Czech Karolina Muchova.
