Russian college student Diana Shnaider, who qualified for the tournament, showed that she is a name for the future.
She took home the first set against sixth-seeded Maria Sakkari from Greece.
The 18-year-old from Moscow is studying in North Carolina in the United States, and in the event of a victory, would be forced to choose whether she would accept the prize money or the studies, according to The Tennis Podcast.
Now that was not needed, as the final numbers were finally written 3–6, 7–5, 6–3 in Greek.
- It was extremely tough.
There were times during the match when I thought I was going to lose.
But then I found ways to come back and close the match, because it wasn't easy, she says after the match.
Was there anything about her playing that surprised you?
- I know her from before.
But the power she has in her forehand and her serve I haven't seen in a long time from such a young player.
We know that Cocco (Gauff) is the same age, but she is much taller and bigger built.
The speed and acceleration she (Shnaider) has in those strokes was impressive, and the way she moves.
Annoying cheers
The meeting was also emotional, with Sakkari irritated by the Russian's victory cheers.
- If she screams one more time in my face, I will call the referee, the Greek was heard to say, according to the news site News.com.au.
Sakkari plays down the incident after the match.
- During a match you can be very charged, and the way some people celebrate their points is not appropriate.
And I was unhappy with that, and she didn't do it anymore – which was kind of her, she says.
World number one Swiatek on
Third-seeded American Jessica Pegula knocked out Belarusian Aliaksandra Sasnovitch in two straight sets.
However, Sasnovitj, ranked 38 in the world, managed to take the second set to a tiebreak.
World number one Iga Swiatek is also through to the third round of the year's first grand slam, after victory against Camila Osorio from Colombia, ranked 82.
