Bastad, Sweden (Sports Network) - Reigning champion Polona Hercog upset second-seeded Julia Goerges in Wednesday's second-round action at the $220,000 Swedish Open.

The unseeded Slovenian Hercog handled the German Goerges 7-6 (7-4), 6-2 in 1 hour, 42 minutes on the red clay at Bastad Tennis Stadium.

Hercog beat Sweden's own Johanna Larsson in last year's Bastad finale.

Additional upsets were avoided when fifth-seeded Russian Anastasia Pavlyuchenkova topped Spaniard Silvia Soler-Espinosa 6-4, 6-0 and seventh seed Mona Barthel of Germany dismissed Ukrainian Kateryna Bondarenko 6-2, 7-5.

One other second-round result saw Bulgarian Tsvetana Pironkova erase Ukrainian Lesia Tsurenko 7-5, 6-3. Pironkova will meet Hercog in Friday's quarterfinals.

The first round concluded Wednesday when France's Mathilde Johansson drilled 38-year-old American lucky-loser Jill Craybas 6-4, 6-1 and the aforementioned Larsson got past Belarusian Olga Govortsova 7-6 (8-6), 4-3, as Govortsova retired due to an illness.

Craybas entered the draw Tuesday when top-seeded Italian star Sara Errani pulled out, citing a shoulder injury. The surprise French Open runner-up Errani was fresh off her clay-court title in Palermo in her native Italy last week.

The 2012 Bastad champion will earn $37,000.
