Canadian world champion Ethan Katzberg won the men’s hammer at the Paris Olympics on Sunday, uncorking a mammoth heave with his first throw to clinch the gold medal. The charismatic 22-year-old from British Columbia registered 84.12m with his opening effort to leave his rivals trailing throughout the competition at the Stade de France. Katzberg’s superb first round toss was more than four metres further than his nearest rival, Hungary’s Bence Halasz, who took silver with a throw of 79.97m. Ukraine’s Mykhaylo Kokhan took bronze with a throw of 79.39m.
