Tuesday at the AEGON International has seen the top three women's seeds fall in round one but victories for Britain's Laura Robson & Heather Watson.

The No.1, 2 & 3 seeds Radwanska, Kvitova and Wozniacki lost their matches on a sunny day on Centre Court and Court 1 at Devonshire Park, Eastbourne.

But on Court 2 there were successive victories for the two British players remaining in the singles draw as Laura Robson and Heather Watson recorded strong wins.

Christina Mchale came through the longest battle of the day on Centre Court as she defeated former world No.1 Caroline Wozniacki 6-1, 6-7(7), 6-4.

"I'm really excited to have pulled that one out," said the American after her three set victory, "I thought I played well so I'm really happy."

Wozniacki put the loss behind her to look ahead to Wimbledon, saying: "Obviously I would have liked to have won that match, but at least I got some points in and, you know, I'm just trying to work on a few things before Wimbledon."

The first match of the day on Centre Court had seen 2010 Eastbourne champion Ekaterina Makarova defeat reigning Wimbledon champion Petra Kvitova 7-5, 6-4, and swiftly following the Czech No.2 seed out the tournament was top seed Agniseszka Radwanska.

The Polish world No.3 went down 6-2, 6-4 to 2010 Wimbledon semi-finalist Tsvetana Pironkova on Court 1.

Next up for Kvitova's conqueror, Makarova, is Britain's Laura Robson who pulled off an impressive comeback to defeat Spanish world No.49 Maria Jose Martinez Sanchez 3-6, 6-2, 6-2.

"I was really happy with how I played in the second and third set. She's a really experienced player, and that's why I'm really happy to have got the win."

Following Robson onto Court 2 was another young British hopeful, Heather Watson, who was a 6-3, 6-4 winner over Hungarian qualifier Greta Arn. The British 20 year old said afterwards:

"Brilliant day. I'm very pleased with myself to get through. I was pretty much nervous throughout the whole match. I got through it, and I thought I played quite well."

Watson will play Lucie Safarova in round two, the seventh seed from the Czech Republic.
