ULSAN, South Korea (Interstat) — Kim Minhyeok’s 12th-minute goal was the difference as South Korea’s Ulsan secured a 1-0 victory over Japan’s S’frecce Hiroshima in an AFC Champions League match Tuesday at Munsu Cup Stadium. The midfielder finished a play set up by assists from Lee Jaeik and substitute Tsukasa Shiotani. The result defied a pregame projection from Interstat that forecast a 1-1 draw. Both teams were opening their group stage campaigns in the continental tournament. Ulsan improved its form after a recent loss in another competition, while Hiroshima’s attack was held in check throughout the match.
