It's a credit to English badminton that we have so many good pairs Anthony Clark

Clark and Kellogg were delighted to finally beat Robertson and Emms after losing to them in the final last year - as well as missing out in the World Championships.

"It's the first time we've ever beaten them in a tournament," said Clark. "The shuttles were slower and that helped.

"Nathan and Gail are too good when the shuttles are really fast. But we worked hard at turning strong defence into attack.

"It's a credit to English badminton that we have so many good pairs."

There was further success for Clark and Kellogg in the doubles events.

Clark paired up with Robert Blair to beat Chris Langridge and David Lindley 21-16 21-15.

And Kellogg and Emms won the women's doubles, beating Joanne Nicholas and Natalie Munt 21-17 21-17.
