Career

He represented Cuba at the 2008 Summer Olympics and also at the 2009 World Championships in Athletics. Díaz emerged as one of a talented trio of Cuban male decathletes along with Leonel Suárez and Yordanis García. Cuban combined events coach Gabino Arzola stated in 2005 that it was his intent to see three Cubans compete in the decathlon at the 2012 Olympic Games.

He set a decathlon personal best of 8057 in his home town of Havana in March 2008, breaking the 8000-point barrier for the first time.

Díaz"s first appearance on the global stage came soon after at 2008 Summer Olympics, but he did not compete in his specialist event but rather as part of Cuba"s 4×400 metres relay team with Yunier Pérez, William Collazo and Omar Cisneros. The team failed to progress beyond the heats stage of the competition.

Díaz was selected to represent Cuba in the decathlon at the 2009 World Championships in Athletics along with Suárez and García. He was in second place after five events (having scored 4512 points) and although he had slipped to ninth place by the end of the competition, he managed to significantly improve his personal best to 8357 points.

This score gave him eleventh place on the season"s decathlon rankings.
