PORTOROZ, Slovenia - Sara Errani had been one of the best players at the Banka Koper Slovenia Open over the last few years, winning 10 of her last 11 matches at the event; but what happened Wednesday night was a far cry from that, as the No.4-seeded Italian crashed hard to Anna Chakvetadze.

Errani won here in 2008 and made the final in 2009, barely losing to Dinara Safina, then the No.1 player in the world, 7-5 in the third set. She won her first round match this year in straight sets but against Chakvetadze in the second round was totally outclassed, losing 61 62 in only 58 minutes.

"I was expecting more from her side, but I don't think she played her best at all," Chakvetadze told reporters after the match. "I just took my chances and I'm happy to be in the quarterfinals playing in my first year here."

Chakvetadze was ranked as high as No.5 a few years ago but in the spring fell out of the Top 100 after a disappointing last 12 months; she is showing improved form as of late, and now is in her second quarterfinal of the season.

"I want to get back to the top, but it's tough to say," the Russian added. "I haven't played the Top 10 players a lot recently. I played Serena a few weeks ago and lost pretty easily. I have to play more to get the feel again."

Next for Chakvetadze is No.6 seed Vera Dushevina, who hung tough to beat Virginie Razzano, 46 75 62. Razzano was two points from the win, serving for the match at 64 54, 30-15; but it wasn't to be for the former Top 20 player.

"I had never played with her. It was really good tennis," Dushevina said. "She had chances to win the match, but after the second set I knew I was stronger and fitter, and I saw she was a little bit tired."

Other winners were No.7 seed Polona Hercog, who got past fellow Slovene Katarina Srebotnik in a two-hour, 48-minute marathon, 64 67(3) 63; and Stefanie Voegele, who beat 2006 Portoroz winner Tamira Paszek, 75 64.

"I played well and I'm happy I got through," said Voegele, who had upset No.2 seed Petra Kvitova in the first round. "I'll play a Slovenian next, so maybe I'll play on Centre Court. I played there last year so I know what it's like."
