Caribbean International Classic. The race would be his greatest challenge as he would be racing against the best horse all the way from Venezuela to Panama. He was riding on a 13 race winning streak going into the race and for once that streak would be truly tested. At the start, he did his normal schtick of stalking while Heisenberg took the lead however Don Paco tried to move into third to not let Heisenberg getaway. However, by the far turn, he had nothing left and faded to fifth while Heisenberg led all the way and took the race. Despite this, he would continue his career after the defeat however he never had the same level of supremacy that he had before. He did rack up one more graded stakes win in the Grade 2 Antonio R. Barcelo Classic Stakes at the age of 4 but besides that, all of his victories were simply in allowance company. After a 4th in the grade 1 4th of July Cup, he was sidelined for a whole year. When he returned he simply was not the same. Returning from the injury he would only win 2 times over the course of his 5 and 6-year-old seasons. Both in allowance company. He would run his last race in the Antonio Fernandez Castrillon Classic against fellow Puerto Rican triple crown winner Arquitecto. A horse who had defeated him 3 other times in stakes company. This would be the fourth time as Arquitecto ran away with the race while Don Paco was a well-beaten third by over 16 lengths. After that, he was retired to stud.
