Near the deadlines, the auditions were unable to find any male anchors; Enriquez was the last person to be there. They told to him "Ikaw, gusto mag-anchor?", but he refused, joked on saying that his face never fits the coverage, saying it's up to the network to do the decision. He was ready, but nervous, scared and cold, his first part was Karen Davila. As the morning slot begins, Enriquez's first words on TV were "Ito po ang Decision '95, Operation: Bantay Boto, dito lamang po sa GMA". Months later, the network executives called for him to come back; they told him that he would anchor a 15-minute newscast, in the early evening slot, together with Davila, saying to make the news delivery fast, aside being delayed.
