Ahead of the 2013–14 season, Quintero signed a new contract with Santos Laguna that lasted until 2016. He made his first appearance of the season on 23 July in a Copa MX match against Club Atlético Zacatepec, scoring once in a 3–0 win. The Apertura 2013 Copa MX was Quintero's first time competing in the Copa MX as the tournament had not been played from 1996 to 2012 and teams who were competing in a continental competition did not participate. In Santos's next Copa MX match, Quintero scored twice to help "Los Guerreros" record a 3–3 draw with Zacatepec. He would score a brace in the final match of the group stage, a 3–2 win over Tigres UANL, however it was not enough as Santos failed to advance out of the group. Quintero's 5 goals saw him finish as the second highest scorer of the tournament.
