SYDNEY: Morgan Mitchell and Luke Mathews automatically qualified for this year’s Rio Olympics after victories at the Australian Athletics Championships in Sydney on Saturday. Morgan, undefeated in the women’s 400-metre this year, won the one-lap final in an Olympic Games qualifying time of 51.84 seconds. Mathews’ win, in the 800m, was more dramatic after Olympic Games qualifier Josh Ralph tumbled out of contention and finished eighth. Mathews, 20, went on to win in 1:46.20. In the men’s 400m final, London 2012 Olympic finalist Steven Solomon won his fourth Australian 400m crown in a time of 45.50, missing the Olympic qualifying mark by a mere 0.10 seconds.
