Tuhia he haere tonu mo tenei waahanga - I angitu a Rojas i tana angitu tuatahi i te whakataetae peke i te 2011 South American Junior Championships, i wikitoria ai ia i te peke teitei. Na tenei wikitoria, i whakawhiwhia ki a ia tana hu tuatahi, na Marco Oviedo o te Venezuelan Athletics Federation (FVA) i muri i te wero a Velásquez ki te FVA ki te tautoko i a ia mena ka wikitoria ia. I hinga ia i nga whakataetae 2012, i whakahaere i te tuawha anake, engari i pai ake tana mahi i nga whakataetae taumata teitei i taua tau, ka peke ki te takiwa tuaono i te Ibero-American Championships
Ka riro i a ia te mētara parahi i te Whakataetae o Amerika ki te Tonga o te Runga o te 23.
