Kashiwa Reysol condemned Gamba Osaka to their third match without a win with a 1-0 victory in Tuesday’s rescheduled matchday 13 clash.
Eduardo netted the only goal of the game between Japan’s pair of AFC Champions League quarter-finalists with a 12th minute header from an improbable angle.
The win in the penultimate round of the MEIJI YASUDA J1 League first stage means Reysol picked up all three points at home for the first time this season.
Despite their progress on the continent, Tatsuma Yoshida’s side have endured a stop-start season in the league, sitting three points off the bottom three.
Champions Gamba will meanwhile be concerned with their failure to avoid defeat at Kashiwa Stadium after missing several opportunities to score.
