PORTSMOUTH (USA): 400m Beijing Olympic champion LaShawn Merritt, who reached US Olympic team at both 400 and 200m, told reporters about his priority in Rio. “The main focus is the 400, that is the event I really want to win. As for the 200, right now I have the fastest time in the world, I enjoy the event, over these next couple of weeks I’ll kind of learn how to run the event a little better. And as for the 4Ã—400 relay, everybody loves that event. That closes the show,” Merritt said.
