The Nyanza-based side had hoped to get something from the Dockers but the Paul Nkata led side had other ideas. Edwin Lavatsa was in a devastating form as he became the first player to hit the back of the net four times this season.
The ex-Gor Mahia man made a joke of the opposing defenders as he exposed them badly in front of the home fans; he scored his first in the 19th minute before adding his second minutes later before completing his treble later into the match.
The other two goals were netted by Anthony Wambani and Baron Oketch, who is on loan from K'Ogalo.
The sugar millers scored their consolation courtesy of Ambrose Ayoyi and Anthony Otuoma.
