Heather Jameson finished eighth in the T37/38 long jump final at the IPC Athletics World Championships in the Rhone Stadium, while John McCarthy was fifth in the T51 200m final.
There was disappointment for Amanda Crotty however, as she ran well below her best in the T12 1500m semi-final.
Jameson is laying the groundwork for a promising future. Having already competed at the London Paralympics and Lyon World Championships in the 100m, 200m and long jump at the tender age of 16, she has laid a firm foundation on which to build her road to Rio.
The Dubliner did well to make the final eight, holding off the late challenge of local favourite, Anais Jaron. That was despite fouling twice, but in a very tight affair, her initial attempt of 3.87 earned sufficient points (801) to squeeze through.
She was red-flagged on her next attempt again, but tweaked her timing and approach sufficiently to hit the board correctly in her fifth and sixth jumps.
They were both measured at 3.70m and though Jameson momentarily moved up to seventh on countback, fellow 16-year-old Matthildur Thorsteinsdottir (Iceland) managed to leapfrog her once more in a competition won by Russian Margarita Goncharova.
Meanwhile McCarthy portrayed his championship pedigree once more with another personal best of 44.85 in his re-run final.
The initial decider took place yesterday afternoon, but an appeal by Italian Alvise de Vidi was upheld by competition judges and Algerian Mohamed Berrahal, who finished second, was disqualified.
This proved a completely different race, with Mexican Edgar Navarro retaining his title and setting a new championship record.
He was third yesterday and Toni Piispanen, who won that contest, had to be content with the silver when it counted.
The result was slightly bittersweet for McCarthy too in that while he added a PB to another personal landmark in the 100m, he actually finished in a quicker time yesterday of 43.62.
It was a tougher day for Crotty, with Kevin Nolan guiding her, the 28-year-old struggled in the intense heat that has threatened a postponement of the afternoon proceedings. The Cork native finished fourth in her semi-final in a time of 5:27.34, more than 12 seconds outside her best.
