EUGENE, Oregon: World Championships bronze medallist O’Dayne Richards continued his early season struggles in the shot put after posting a modest 19.09m on the opening day of the 2016 Prefontaine Classic at the University of Oregon’s Hayward Field in Eugene earlier. Richards, who is still trying to regain his best form after a leg surgery earlier this year, says he will have to remain patient and continue to work hard, but was of course left disappointed with his result. “There’s still a little bit of time but I think I was too cautious especially on my first throw. Its going to take some time and I know that I must remain calm and patient,” Richards told The Gleaner after his event. After fouling on his first attempt, Richards registered his best mark of the day on is second before going 18.30m on his final effort. World champion Joe Kovacs (USA) won the event, avenging his loss to Kurt Roberts at the recent Shanghai Diamond League with a world leading 22.13m effort on his last attempt. Kovacs came into his own on his last three efforts, landing the implement at 21.57m and 21.66m before capping off the competition with the first 22m mark of the season. Second place went to Tom Walsh (New Zealand) with 20.84m, with Reese Hoffa (USA), 20.58m finishing third. Pawel Majewski (Poland) was too good for the rest of the field in the men’s hammer throw with a 80.28m mark. He was followed by Dilshod Nazarov (Tajikistan), 78.12m and Wojceich Nowicki (Poland), 76.86m. Olympic and world champion Sandra Perkovic (Croatia) was not at her best, but she was still the class act in the women’s discus event, winning in 68.57m ahead of Nadine Muller (Germany), 65.31m and Melina Robert-Michon (France), 63.39m. Brittney Reese (USA), 6.92m was tops in the women’s long jump with Ivana Spanovic (Serbia), 6.88m, finishing second and Lorraine Ugen (Great Britain), 6.76m taking third place.
