In January 2015, Park officially joined Gyeongnam FC and he would make his debut in a league game against Ansan Police on 22 March 2015 in a 0-0 draw. This would be followed by his debut goal for the club in a league match against Chungju on 5 July 2015 in a 1-1 draw. Park would establish himself as an integral part of the team's defence and go on to aid the club to win the 2017 K League Challenge division and promotion to the top tier. Park and Gyeongnam FC would continue their upward trajectory and the club surprisingly came runners-up in the 2018 K League 1 campaign.
