Richmond Lamptey's second half goal clinched the points for Asante Kotoko in the 1-0 win over his former side WAFA on Sunday at the Baba Yara Stadium.
The midfielder fired home a rebound from inside the box after his earlier strike had been intercepted by a WAFA defender.
He has now registered his second goal for the Porcupine Warriors.
The win keeps the Porcupine Warriors on track with back-to-back victories.
