Eighth-seeded Kvitova, was stunned by teenager Zarina Diyas – who was born in Almaty, Kazakhstan but is based in Prague, which helps explain the wildcard she was awarded this week.
Diyas, making her Tour main draw debut and ranked No.295 in the world, justified the faith of tournament organizers when she beat fellow junior and qualifier Kristina Mladenovic quite handily in the first round. But despite a string of strong results on the ITF Circuit in recent months, there was no reason to suspect she would dismantle the world No.63 with such aplomb, 64 62.
