Striker Shinzo Koroki scored his 10th J. League goal of the season and Fabricio netted an injury-time penalty as Urawa Reds beat Kawasaki Frontale 2-0 on Wednesday night.
The victory was the second in a row against top-three opposition for Reds, following an emphatic 4-1 win away to league leaders Sanfrecce Hiroshima on Saturday.
Reds struck the winner in the seventh minute after right back Takuya Iwanami played a ball from inside halfway to Yuki Muto. The forward made a run down the right wing and crossed to Koroki, who neatly chipped past diving Frontale keeper Jung sung-Ryong from close range.
