Hiroshi Morita's second-half strike saw unfashionable Omiya Ardija claim local bragging rights with a shock 1-0 win away to the J. League-leading Urawa Reds on Saturday.
Omiya belied its lowly status in a tightly fought derby at Saitama Stadium 2002 and Morita's goal was just reward for a blood-and-guts performance that earned the visitor three precious points in its bid to beat the drop.
Urawa saw its four-point lead sliced to one as in-form Brazilian striker Bare made it five goals in two games with a hat trick to power second-placed Gamba Osaka to a 4-1 win at Nagoya Grampus Eight.
