Pendleton progresses in Melbourne
Victoria Pendleton, fresh from her ninth Track Cycling World Championships title, began her bid for a 10th by advancing at the second time of asking in the women's keirin on day four in Melbourne.
Two riders progressed from each of the four keirin heats, with the remainder falling into the first-round repechage.
Pendleton finished third behind France's Clara Sanchez and Australia's Kaarle McCulloch before defeating Monique Sullivan of Canada and Russia's Viktoria Baranova in her repechage heat to go through at the second attempt.
Defending champion Anna Meares, beaten by Pendleton in an epic semi-final on Friday, needed no second invitation and advanced by winning the first heat.
Laura Trott led the women's omnium after four events.
The 19-year-old team pursuit world champion and world record holder clocked three minutes 31.789 seconds to place third in the three-kilometre individual pursuit.
Australia's Annette Edmondson, who had held the joint overnight lead with the Briton, was fourth in the discipline to slip one point behind with two events remaining.
In the non-Olympic 4km men's individual pursuit, Geraint Thomas clocked 4mins 17.265secs.
The Briton was in the first heat and his early advantage lasted until the fifth when New Zealand's Westley Gough clocked 4:17.001.
Thomas was fifth and is now set to recuperate for Sunday's Madison, which he is set to ride in partnership with Ben Swift.
