Urawa Reds remained unbeaten through 11 games and at the summit of the J. League after thrashing FC Tokyo 4-1 in a top-of-the-table clash on Saturday.

Tadanari Lee, Takahiro Sekine, Yuki Muto and substitute Tsukasa Umesaki scored for Mihailo Petrovic's men in an unexpectedly one-sided contest at Saitama Stadium. Ryoichi Maeda came off the bench to net a consolation for the visitors, his first goal in a Tokyo shirt.

Reds, on 27 points with a game in hand, moved four points clear of Gamba Osaka, Tokyo and Sanfrecce Hiroshima, who drew 2-2 away with Kashima Antlers. Gamba, in second place on goal difference, were held to a 1-1 draw at home by Kawasaki Frontale.
