British wild card Richard Bloomfield is refusing to get carried away by his first ever win at Wimbledon, especially with Tommy Haas and Roger Federer standing in his way.

The 23-year-old from Norwich achieved the best win of his career, a 6-1 6-2 6-2 trouncing of grass-court novice Carlos Berlocq, the world number 89 from Argentina, on a day of mixed fortunes for the Brits.

Bloomfield, beaten at the first hurdle in 2003 and 2004, bridged a gap of 170 places in the world rankings to make it third time lucky and join Tim Henman, Andy Murray and Jamie Delgado in the second round.

The Cheltenham-based player today meets Germany's former world number two Haas for a place in the last 32, with Federer or Henman lying in wait in the fourth round if he should get that far.

"I've got a tournament next week in Dublin, that's how confident I am of making the second week," he said.

"Obviously, it's going to be a very tough match. Hopefully, I can put up a good show. We'll see what happens.

"It's going to be a great match, playing someone of that level. He's been injured but over the last year or so, since he's been back, he's been playing really well. He's getting back up there.

"The more matches you win, the more chances you're going to play a seed. But to get to the top, it's all about winning matches.

"Obviously, I saw Tommy Haas' name just above me, you can't really miss a name like that. I think above that is Roger Federer and Tim Henman."

Delgado became the second lowly-ranked Briton to make it through to the second round, courtesy of a 6-4 6-2 3-6 3-6 6-3 victory over German qualifier Michael Berrer.

Glasgow-born Jamie Baker lost 6-3 7-6 6-4 6-3 to Andreas Seppi, the world number 68 from Italy, and there were defeats for Alex Bogdanovic, Naomi Cavaday, Katie O'Brien and Anne Keothavong.

Today Melanie South and Sarah Borwell aim to make up for the disappointments of their British female colleagues when they finally play their opening-round matches.

The 20-year-old South, from Surrey, faces a daunting clash with Italian 11th seed Francesca Schiavone on one of the show courts while Cheltenham-based Borwell plays Marta Domachowska, of Poland.

Scotsman Alan Mackin takes on Marcos Baghdatis, the 18th seed from Cyprus, Martin Lee meets veteran Belgian Dick Norman and Josh Goodall plays Melle Van Gemerden, of Holland.
