England's Victoria Pendleton and Australian sisters Kerrie and Anna Meares had little trouble in booking their semi-final places in the women's sprint semi-finals on Wednesday.

Kerrie, who is almost a year to the day older than sister Anna, did not even need to put a foot on the pedals to qualify.

Her opponent, Malaysia's Hsu Min Chung, decided to pull out of the best-of-three contest.

Meares was therefore able to watch in comfort as Anna overcame the challenge from Denise Hampson of Wales.

Pendleton clocked the fastest time of the round to beat fellow English cyclist Melanie Szubrycht.

The three winners now join Canada's Lori-Ann Muenzer in Thursday's semi-finals here at the National Cycling Centre.

Muenzer clocked a Commonwealth Games record time of 11.452 seconds in the morning qualifiers to give early notice of her ability.

The 36-year-old bronze medallist at the Kuala Lumpur Games four years ago was given a bye in the quarter-final because two of the scheduled competitors pulled out of the first round.

"When I woke up this morning I knew I had good legs," Muenzer said. "I knew they were there, clean, fresh and ready to rip up the track."

The Meares sisters have avoided facing each other in the semi-finals. Anna takes on Muenzer while Kerrie faces Pendleton.
