Busan IPark lost 0:1 to Ansan Greeners in the K-League 2 regular season on 5 September. The away side took the lead in the thirtieth minute through Marlon, who finished off a rare chance to extend his team's unbeaten streak. By then the hosts had already dominated possession and territory, but could not find the net.
Both managers made changes at the break, bringing on Lee Dong-Su and another player for Busan. The visitors held their shape and looked dangerous on the counter, while the home side pushed forward with increasing urgency. And here's the thing — Busan had 152 attacks to Ansan's 67, yet only four shots hit the target.
Kim In-Sung picked up a yellow card in the fifty-second minute, a sign of the growing tension. Ansan responded with their own substitutions, bringing on Gabriel Honorio and Ahn Hyun-Beom in quick succession. The visitors' efficiency was stark: three shots on target yielded a goal, while the hosts managed four attempts without reward.
Marlon was substituted in the sixty-sixth minute, having done all the damage. Park Hye-seong and Jang Hyun-Soo both received cautions as the match wore on, with Busan adding Son Hwi and Ansan replacing Park Kyu-Min late on. The final whistle confirmed a hard-fought victory for the visitors.
The result leaves Busan in sixth place with thirty-eight points from twenty-four games, while Ansan sit fifteenth with twenty-two. For the hosts the defeat ended a run of three consecutive draws, a streak that had built some confidence. To be fair, Ansan's form has been inconsistent, but this was a performance that mattered.
