Lois Toulson finished sixth in the first senior international final of her career at the FINA Diving Grand Prix in Gatineau, Canada.
The 15-year old World Junior silver medallist saved her best performance for the final, scoring 333.45 for her five dives, including 79.50 for her penultimate dive and 80 – the highest score of the round – for her last dive.
The strength of the field ultimately proved too deep for the British champion, who had the lowest tariff list of the six finalists.
China’s Ji Siyu claimed top spot on 419.45 ahead of Canada’s Roseline Filion on 391.30 and France’s Laura Marino on 370.10.
Great Britain also had a couple of synchro pairs in action on the final day in Canada.
City of Leeds’ James Denny and Matty Lee combined to finish fifth in the 10m Synchro on 381.06 while Edinburgh’s Grace Reid and Leeds’ Katherine Torrance scored 272.28 to finish sixth in the 3m Synchro.
