Ivanovic is currently ranked ninth in the world.

This is considered the second surprise in the 2014 US Open women’s singles event. Compared to the defeat of fourth seed Agnieszka Radwanska to Chinese player Peng Shuai a day earlier, Ivanovic’s elimination in the second round can be seen

No longer in his prime, the Serbian star is nonetheless ranked number eight, while his opponent is only 22 years old and has never before won a ticket to the third round of a Grand Slam tournament.

“This was my best match since the beginning of this year.

And Ivanovic expressed his disappointment: `I played at a bad pace in this match, and lost too many points easily because of self-inflicted errors.

US Open `Queen` Serena won overwhelmingly in the second round with a score of 6-1, 6-0 against compatriot Vania King.

Serena still proves herself to be the number one candidate.

King once won the women’s doubles event at the 2010 US Open, but in the world women’s singles rankings she is currently only ranked 80th. There is a big difference in level between this 25-year-old tennis player and her famous senior Serena.

If she maintains her current form, the Williams sister can absolutely win her sixth championship title at the last Grand Slam of the year.

The world number one’s next opponent in the third round will be compatriot Varvara Lepchenko or German tennis player Mona Barthel.

Serena Williams 2-0 Vania King

Third seed Petra Kvitova also won 6-4, 6-2 against her less famous compatriot Petra Cetkovska.

`Grand Slam matches are always very difficult, so I am satisfied with what I am doing at this US Open,` Kvitova said after the match.

Petra Kvitova, 24 years old, has two Grand Slam titles in her career, but both at Wimbledon (2011 and 2014).

Meanwhile, No. 16 seed Victoria Azarenka started the second round match poorly, almost leading 0-4 in the first set.
