Jeju United remained four points clear on top of the K-League table with a fighting 3-2 home win over Gyeongnam.
The visitors took a two-goal lead through Bit-Garam Yoon and Lucio who netted twice in quick succession before the 20-minute mark but the league leaders fought back and were on level terms by the half-hour mark through a Eun-Jung Kim penalty and a Santos Junior equaliser.
Just prior to the hour-mark, Kim put Jeju ahead and the scoreline stayed at 3-2 until the final whistle.
