Suwon Bluewings missed the chance to join Jeonbuk Motors at the top of the K-League standings following a surprise 3-0 defeat at home by Gyeongnam.
Two goals from Kim In-han in the 14th and 50th minutes, with a Rocha Caique strike in between, saw Suwon succumb to their fifth loss of the season. They remain three points behind Jeonbuk at the summit and a point behind second-placed FC Seoul.
Busan I'park failed to break into the top five with a last-minute 2-1 loss to Incheon United. Han Kyo-won fired Incheon ahead after 57 minutes, while Yoon Dong-min equalised in the 78th minute. However, a last-minute goal from Jung In-whan sealed the win for the visitors, who move out of the bottom three as a result.
Sangju Sangmu Phoenix climbed off the bottom thanks to a 1-0 victory over Pohang Steelers, courtesy of Kim Min-woo's early strike.
Finally, Seongnam Chunma and Chunnam Dragons shared the spoils after a 1-1 draw. Ju Sung-hawn's opener for Chunnam was cancelled out by Hong Chul.
