The delegation included two short-distance runners and one judoka : Kenneth Medwood , Kaina Martinez and Eddermys Sanchez .

Medwood was selected as the flag bearer for both the opening and closing ceremonies . Medwood reached the semifinals of the men 's 400 metres hurdles before he was eliminated from competition while Martinez did not progress farther than the quarterfinal stage of the women 's 100 metres . Sanchez was defeated by his opponent Miklós Ungvári of Hungary in a 19-second match in the Round of 32 of the men 's half-lightweight judo competition
