Hearts of Oak collected the Ghana Premier League derby spoils after nicking a 1-0 win at Asante Kotoko on Sunday.
He collected a pass from Winful Cobbinah before bearing forward and then cut onto his right foot to rifle past Felix Annan between the sticks for Kotoko.
Two minutes to full time, Asante Kotoko SC came too close to getting the equalizer but a free header by Yacouba missed the goal by a whisker.
It is the first victory for the Phobians in four matches.
The Porcupine Warriors head coach Paa Kwesi Fabin handed new recruit Songne Yacouba a debut whilst the opposite trainer gave Kojo Obeng Junior his maiden appearance since joining.
