Bucharest: Second seed Roberta Vinci was a surprise casualty at the Bucharest Open on Thursday as she lost in straight sets to Serbian Aleksandra Krunic.
Vinci eased past Timea Babos 6-2, 6-1 in her first round match on Wednesday but the Italian came unstuck in equally-easy fashion, losing 1-6, 1-6 to Krunic, who now faces Polona Hercog in the quarter-finals.
Another result that raised eyebrows saw the exit of number four seed Julia Goerges as Danka Kovinic triumphed 6-4, 6-7 (6/8), 6-2.
Romanian Monica Niculescu also made it through to the quarter-finals.
The number three seed dropped just five games as she defeated Teliana Pereira of Brazil in straight sets, 6-2, 6-3.
