Derval O’Rourke finished 8th in her 100m hurdles semi-final at the World Junior Athletics Championships in Chile today. Derval was fastest out of the blocks, but failed to hang on to the leading junior Susanna Kallur of Sweden, who cruised to victory in 13.03. Nevertheless, Derval ran a fine time of 13.76, her second fastest ever. Elsewhere, Emily Maher finished a very credible 7th in the final of the 100m.
