Mastracci was in the boat with Sarah Black of Ottawa, Ontario, Carolyn Ganes of Saskatoon, Saskatchewan, Susanne Grainger of London, Ontario, Kristen Kit of St. Catharines, Ontario (coxswain), Jennifer Martins of Toronto, Ontario, Cristy Nurse of St. Catharines, Ontario, Lisa Roman of Vancouver, British Columbia and Christine Roper of Victoria, British Columbia as Canada won a bronze medal in the women's eights.
Mastracci, Roper, Black and Nurse previously won a silver medal in the women's fours competition on Friday.
The fact that Canada came away with three medals in women's rowing at the World Championships was a strong showing. (The Canadian team of Emily Cameron of Summerside, Prince Edward Island, Kate Goodfellow of Perth, Ontario, Antje Seydlitz-Kurzbach of Smithers, British Columbia and Carling Zeeman of Cambridge, Ontario also won a silver Saturday in the women's quadruple sculls).
The reason is that Mastracci was the only female rower that was part of the Canadian women's eights team that won a silver medal at the 2012 Olympic Games in London, and the Canadian team would have been excused if they stated this was a year of transition.
Now the women's quadruple sculls and women's eights will be medal contenders for the 2016 Olympic Games in Rio de Janeiro.
