Badminton

Britain's Joanne Goode and Julie Bradbury, the No 2 seeds, strolled through the third round of the US Open in Orange, California, with a 15- 0, 15-4 thrashing of Russia's Ella Karachkova and Josy Patrick of Canada. Both progressed with different partners in the mixed doubles. Goode and Nick Ponting beat the Canadian pair of Darryl Young and Denyse Julien 15-7, 15-7, while Bradbury and Simon Archer, seeded No 2, overcame Indonesia's Sandiarto and Indarti Isoliana 12-15 15-11 15-9. But Archer and Chris Hunt slid out of the men's doubles, 15-9, 15-1, to the No 2 seeds, Yap Kim Hock and Cheah Soon Kit of Malaysia.

Badminton tests a new scoring system next week which could herald the biggest change in the sport since it began in 1893. Instead of playing best-of-three games, first to 15 points per game, the Dutch Open will experiment with best-of-five games, first to nine points.
