Radwanska, Li Na lead the field
Agnieszka Radwanska takes the top seeding ahead of former French Open winner Li Na at the Aegon International WTA event starting on Monday at Eastbourne, on the south-east coast of England.
Radwanska won the title in 2008 but lost in the first round a year ago.
German Angelique Kerber is third trailed by 2011 Wimbledon winner Petra Kvitova.
Former No 1 Caroline Wozniacki will want to find some immediate success after winning just one round at the French Open.
The Dane, who stood atop the WTA rankings for two seasons, lifted the title at Devonshire Park four years ago but was another first-round victim at the 2012 edition.
Wozniacki, seeded fifth, faces Tamira Paszek in the opening round with Austria's Wimbledon quarterfinalist at the last two editions only winning her first match since January this month at the Challenger level on grass.
Russian Maria Kirilenko begins her grass campaign as sixth seed with a meeting against Serb Bojana Jovanovski while former No 1 Ana Ivanovic of Serbia, a crowd favourite on the blustery south coast, starts against Russian Elena Vesnina.
Marion Bartoli, the 2011 champion, comes in unseeded at this edition but with excitement for the short grass campaign.
"The grass season is so short that it's really hard to play a lot of matches on the surface. So for everyone it's a matter of two, three, maybe the best four matches before going in," said the Frenchwoman.
Former US Open winner Samantha Stosur will play as an unseeded wildcard with her ranking down to 14th after a Paris third round loss. The Australian reached semifinals in her last two Eastbourne appearances, in 2010 and 2011.
She faces a challenge from the start in a match with eighth seed Nadia Petrova.
