Heather Watson recovered from a set down to beat sixth seed Flavia Pennetta as the British number one stormed through to the Aegon International quarter-finals in Eastbourne.

The 22-year-old lost a tight opening set on a tie-break but showed great powers of recovery to turn the match on its head.

Top seed Richard Gasquet advanced into the men's last eight at the expense of Bernard Tomic.

The Frenchman, seeded 13th for Wimbledon, recorded a 6-4 3-6 6-3 success and will face Martin Klizan of Slovakia next.

Klizan beat American Donald Young in their second-round tussle, claiming a 7-6 (7/4) 6-4 victory.

Gasquet's compatriot Edouard Roger-Vasselin also progressed, beating Jarkko Nieminen 6-2 7-6 (7/4), to set up a clash against Denis Istomin.

Feliciano Lopez was pushed by German Tobias Kamke before the third seed came through to win 7-6 (12/10) 7-5.

The Spaniard now faces Jeremy Chardy in the quarter-finals following his 6-4 7-5 win over Carlos Berlocq.

Sixth seed Gilles Simon lost in straight sets in an all-French second-round affair as Julien Benneteau recorded a 6-3 6-4 win.

Benneteau will next face Sam Querrey, whose opponent Victor Estrella-Burgos was forced to retire whilst a set down to the American.

In the women's singles, Watson will next face a tough examination against second seed Petra Kvitova after the Czech beat Varvara Lepchenko 6-1 6-4.

Danish eighth seed Caroline Wozniacki eased to a 6-3 6-3 win over Sloane Stephens to set up a quarter-final clash against Konta's conqueror Giorgi.

German fifth seed Angelique Kerber also made it through to the last eight, despite dropping a set to Alize Cornet and being pushed all the way in the decider before emerging a 7-5 1-6 7-6 (7/3) victor.

Ekaterina Makarova will be waiting for Kerber in the next round after progressing with a 6-3 6-3 win over fellow Russian Anastasia Pavlyuchenkova.

In an all-American quarter-final, Lauren Davis will take on Madison Keys.

Davis beat Daniela Hantuchova 6-3 6-3, with countrywoman Keys coming out on top against Elena Vesnina 7-5 7-6 (11/9).
