Konta, who committed 34 unforced errors during today’s match, may still be suffering from the effects of collapsing during her second round match due to the heat, and then facing a very tough opponent in Belinda Bencic in the third round.
Sevastova, who ousted the third seed, Garbiñe Muguruza in the second round, looked far more relaxed than her opponent today and seemed to be hitting the ball with ease.
Sevastova’s previous best Grand Slam result was a fourth round appearance in the 2011 Australian Open.
She now awaits the result of the Caroline Wozniacki vs Madison Keys match to see who her quarter-final opponent will be.
In another fourth round match, last year’s finalist, Roberta Vinci, defeated Lesia Tsurenko from the Ukraine 7-6(7) 6-2. Her quarter-final opponent will either be Angelique Kerber or Petra Kvitova, who will be playing this evening.
