Seidu Bancey’s goal caused the Phobians’ first defeat after a bright start to the season as his goal helped Kotoko to 1-0 in at the Accra Sports Stadium.
The attacker scored his decisive goal in the first half after Yahaya Mohammed cushioned the ball into his path, allowing his to strike towards goal to earn Kotoko all three points against their fiercest rivals.
Kotoko deserved their single-goal victory as they were the better of the two sides and the result maintains their excellent start to their title defence.
David Duncan, coach of Hearts of Oak had hoped for better luck after string of draws between both sides in their last two meetings but on the day, his side fell short of the needed firepower to back his words ahead of the game.
With victory over their rivals achieved, Kotoko jump to the summit as they maintain their hundred percent start to the season.
