Heather Watson registered her maiden WTA Tour triumph by overturning a top 50 player much to the delight of the supportive Centre Court crowd.
The 18-year-old Guernsey ace, who scythed through three qualifying rounds to reach the main draw, showed hunger and precision to tear apart Canadian Aleksandra Wozniak – the world no48 – 6-3 6-2.
Watson, ranked 344 going into the 2010 Aegon International, had been granted a wildcard to next week’s Wimbledon on the strength of her exceptional results at Devonshire Park.
And the US Open Junior champion impressed in only her third match in the main draw of a WTA Tour event despite the blustery conditions upsetting both players.
Watson admitted: “I’m so so happy, I was really glad to get through the qualifiers but I didn’t want to stop there.”
She saw off compatriot Anna Smith (world no265), Russian grass court specialist Tsvetana Pironkova (no81) and then Serbian Bojana Jovanovski (no108) in qualifying.
But Watson’s latest triumph eclipsed fellow Brit Laura Robson, the 2008 Wimbledon Junior champion, who has not won a main draw match on the WTA Tour but is only aged 16.
It was a day of shocks with world no3 and defending champion Caroline Wozniacki falling to France powerhouse Aravane Rezai in three sets. And the newly-crowned French Open champion Francesca Schiavone of Italy succumbed in straight to Romanian Sorana Cirstea.
Former Eastbourne winner Kim Clijsters, the 2009 US Open champion, returned to winning ways in her first grass court tournament for four years away, by demolishing Belgian Yanina Wickmayer 6-1 6-1 with aplomb.
British stalwart Elena Baltacha progressed against China’s Li Na after the no7 seed retired hurt before the start of the second set of what was a dull contest.
James Ward, the son of a London taxi driver, also made the 2nd Round courtesy of his opponent retiring.
The 23-year-old pulled off a shock success to record his inaugural win in a main draw event. He was leading Feliciano Lopez 6-3 5-4 on Centre Court, but the Spaniard threw in the towel by retiring from the contest citing a shoulder injury to concede defeat to the Great Britain Davis Cup player.
Ward described his victory over no2 seed Lopez as the “biggest of my career”.
However, the world no342 turned down a wildcard into the Wimbledon qualifying competition in order to compete at Eastbourne. He explained: “I was offered the chance to play here and I decided it would be best for my ranking.”
