Duque began his career with Cali-based club Depor FC in the Primera B, where he only played a few friendlies but never received minutes in an official match. In 2006, he joined Deportivo Pereira of the top flight where he had a good spell, scoring 18 goals in 43 appearances.

In January 2011, he joined Deportivo Rionegro of the Primera B to regain form as he was struggling with form in the Primera A. Duque had an excellent spell with the club, and he was the top goalscorer of the 2011 Finalizacion, with eleven goals, and 2012 Apertura, with twenty goals. His goals in the 2012 season led Rionegro to the playoffs of the Apertura, and to the final in the Finalizacion, where Rionegro lost 4-1 on aggregate to Alianza Petrolera.

His performances for Rionegro grabbed the interest of powerhouse club Atlético Nacional, who signed him in July 2012. He made his debut on 18 July in the first leg of the Superliga against Junior, a match which Nacional won 3-1, and becoming one of the few Nacional players to score a brace on their debut.^[3] Four days later, he scored again in a 3-0 victory, with Nacional winning the title 6-1 on aggregate. On 26 August he scored a brace in a victory at Deportes Tolima, but an injury caused him to miss the rest of the 2012 Finalizacion tournament.^[4] In February 2013, Duque was given the all clear by the medical staff and he began to train regularly. He made his return on 9 April 2013, scoring a hat-trick against his former club Deportivo Rionegro
