Semenya impressive again, Merritt also wins in Morocco (Yahoo Sports)

Caster Semenya set another world-leading time and again showed she will be one of the runners to watch at the Rio Olympics, leaving behind a strong field to easily win the 800 meters at the Diamond League meeting in Morocco on Sunday. Former world outdoor champion Eunice Sum was way back in fourth in 1:59.32 at the first Diamond League series in Africa. Semenya was the world champion in 2009, the worlds silver medalist in 2011, and the Olympic silver medalist in London.
