Badminton: Delighted duo in the last eight.

Byline: By Jo Carter

ENGLAND'S premier pair of Anthony Clark and Donna Kellogg marched into the last eight at the All England Championships after an impressive showing against fellow Brits Chris Adcock and Gabrielle White.

No.4 seeds Clark and Kellogg, who received an initial bye after first round opponent Nathan Robertson's withdrawal with a viral infection on Wednesday, sealed their qualification with a 21-14, 21-16 win.

"It was our first game in the arena and it is has been hard," said Clark.

"We are almost three days into the tournament and we have only just started. It can be frustrating - we just want to get into the mix.

"We are pleased with our performance, we played well, moved well and the game was always comfortable."

Meanwhile, Britain's Andrew Smith insists he is capable of breaking into the world's top 10, despite crashing out in the second round at the All England Championships at the NIA.

Despite a strong start against Indonesia's former Olympic champion Taufik Hidayat, Smith, 24, missed out on a place in the last eight, losing 21-15 15-21 16-21 to the world number seven.

"I think I'm close to forcing my way into the top 10," he said.

"I was pleased with my performance and it was a good match. I had chances to win it, but I didn't really take them.

"But there are a number of positives I can take. I just need to continue to play at that level and get more experience."

Elsewhere, women's doubles duo of Gabby White and Jenny Wallwork continued their form to book their place in last eight with victory over sixth seeds Lena Frier Kristiansen and Kamilla Rytter Juhl of Denmark.

Wallwork, 22, and White, 18, raced into an 8-2 lead in the opening game, before romping home 21-12, 21-8 in just 32 minutes.

"If we go on with the mentality we had and play as well as we did out there, we can beat anyone," said Wallwork. "We didn't expect to beat them so comfortably but everything went right for us. That was the best we've played together and hopefully we can continue to improve and progress."
