Derval digs deep as coach backs her for final flourish

If Derval O’Rourke runs like she is capable of running she will make tonight’s final of the women’s 100m hurdles at the Olympic Stadium, according to her coach Sean Cahill.

She has drawn what is by far the toughest of the three semi-finals alongside the world leader, Sally Pearson (Australia), LoLo Jones (USA) and Tiffany Porter (Great Britain), with the first two to go through to the final later in the night along with the two fastest losers.

Despite the strength of her semi-final, Sean insisted O’Rourke can get through after he had watched yesterday morning’s first round heats.
