Talented Polish teenager Agnieszka Radwanska grabbed her third title of the year at Eastbourne on Saturday after a hard-fought battle with Russia's Nadia Petrova.

Radwanska, 19, fought back tears as she was presented with the International Women's Open trophy and a £45,000 first prize - to add to the million dollars already accumulated in her three-year career - after a 6-4 7-6 6-4 win in two hours and 37 minutes.

She also moved up three places in the world rankings to number 11.

Radwanska is back in action again on Monday in the first round at Wimbledon against the Czech Republic's Iveta Benesova.

She said: "I was very emotional out there because I've played so many tough matches in the last few weeks this week and this was the most difficult one here.

"But mostly I was so tired. When you are winning it is great and the money comes along as well but you cannot stop if you want to achieve your goals."

Radwanska won the Wimbledon junior title three years ago - a feat her younger sister Urszula emulated last year. And both sisters will feature in the main draw next week.

Radwanska said: "Of course, we both have great memories there and are looking forward to going back but I have an early match on Monday unfortunately and will do only a short practice tomorrow.

"I'm aiming for minimum third round and I would be pleased to reach the quarter finals just like in the Australian Open. It would continue a good year for me after winning in Thailand and Istanbul as well.

"I'm happy for my mother and my father Robert who is also my coach. When I play in matches like this he is even more nervous than me."

Radwanska's triumph also prevented Petrova, 26, completing a full set of championships on all surfaces.

Both players needed treatment for injuries during the game but fourth-seeded Radwanska's greater mobility carried her through an unlikely final showdown.

After world number one Ana Ivanovic's late withdrawal, Petrova's compatriot Svetlana Kuznetsova, the replacement number one, exited in the second round and former Wimbledon champions Amelie Mauresmo and Lindsay Davenport pulled out with injuries.

Radwanska, who could meet Kuznetsova in the third round at Wimbledon, beat second seed Marion Bartoli, last year's SW19 finalist, in Saturday's semi-final and started favourite against Petrova - one of seven Russians in the field.

But Petrova, who retired injured in last year's Eastbourne semi-final against Mauresmo, was again far below her best, handicapped by a sore knee and hip.

In humid conditions, the first 10 points went with serve.

But Petrova, heavily strapped on her right knee, was soon moving gingerly and there were five breaks in the next seven games - three to Radwanska.

In their only previous meeting, the fourth round of the Australian Open in January, Radwanska had trailed 6-1 3-0 before winning but this time it was Petrova who fought back.

She suddenly found more depth in her shots as the pair swapped service-breaks in the second set and went into a nail-biting tie-break.

The Pole had three match points but it was Petrova who prevailed to win 13-11 - only to call for medical attention and courtside coaching advice after holding for a 2-1 lead in the decider.

Then it was Radwanska's turn to need the trainer for treatment for cramp, but she recovered to take full advantage of a dreadful ninth game by Petrova, who netted an easy lob, then a smash - and finally played a forehand too long to trail 5-4.

Battling Petrova saved a fourth match-point with a brave backhand down the line but could not repeat it, netting her next backhand to lose the match.

She admitted: "I was doing okay and in with a chance until the ninth game in the third when I made some awful mistakes. I don't know where they came from."
