Gauff, the No.18 seed, was made to pay for numerous unforced errors, going down 6-4 6-2.
Seemingly in good form heading into the tournament after two weeks of strong competition in Adelaide, Gauff said she was disappointed with “everything” to do with the match.

“I feel like in the preseason, I worked really hard, and I felt like I was ready to have a good run here,” she said.
“Today I just didn’t perform well.
“I think learning-wise there’s a lot to learn from. I think I didn’t play as free as I normally do today. I think I was playing a little bit tighter than normal.
“So I think next time coming into the first round of a slam, especially after a tough week before, I think I need to just play more free and focus on the moment.
Downing Gauff was not Wang’s first time causing a major upset at the Australian Open after she stunned Serena Williams at Melbourne Park two years ago.
Speaking to the media post-match, Gauff said she was not surprised by Wang’s efforts despite her defeater being ranked outside of the top 100.
“For me, ranking is just a number,” she said.
“Obviously paper-wise I’m supposed to win the match, but I think that even when I was ranked lower before, I always think ranking is just a number.
“Anybody is capable of winning anything, and especially in the US Open, we saw that.
“So I think for me, yeah, ranking-wise I wasn’t really thinking about me being ranked higher or anything like that. I was just trying to win the match.
“But today she played well. I think she did a good job of keeping the ball deep in the court. I wasn’t able to really be comfortable today”
