Jade Jones kicked down the door to the taekwondo final, but it was heartbreak for her Team GB colleague Martin Stamper, who must fight for bronze after losing his semi-final to Servet Tazegul.
Unseeded Jones scored a 10-6 win over Taiwan’s Li-Cheng Tseng to guarantee herself at least a silver medal, while Stamper was edged out of his shot at gold in a 9-6 defeat to Turk Tazegul.
Earlier in the day Jones, 19, fought against Japan’s Mayu Hamada in the quarter-final and eased through with a 13-3 victory, before Stamper added to the host nation’s joy by coming from behind in the final round to beat Serbia’s Damir Fejzic 8-3.
Jones was first up for Great Britain in the women’s under-57kg category against Hamada and continued where she left off after her earlier win.
At the end of the first round Jones led 3-1 before an aggressive second round increased her margin to 9-2 courtesy of a crucial head-kick and some routine body hits.
The youngster from Flint, North Wales, held her composure in a nervy final round to complete a comfortable 13-3 victory and earn her crack at Tseng.
Stamper had a more difficult route through against talented Serbian Fejzic who, after a stalemate in the first round, established a marginal 2-1 lead at the end of the second.
But the Liverpudlian fighter came out strongly in the final round to finish with a flourish and win 8-3 after a series of body shots and good defensive work.
