He was fifth in the 400 m, easily beaten by Yeimer Lopez, but finished the competition on a high by winning the relay gold with Sanjay Ayre, Green and Steele, running a Games record of 3:01.78.

He again was a semi-finalist in the men's 400 metres, but the Jamaican relay team performed poorly in the event final, failing to match their time from the heats and finishing in last place.

He was the Jamaican champion the following year, but his third global appearance – at the 2009 World Championships in Athletics – held similar results; he finished third in his semi-final and was eliminated in the heats in the relay.
