The outstanding matchday 6 fixture was played on Wednesday with the Mauves and Yellows winning thanks to the defender’s calm finish from 12 yards.
The contentious decision was awarded 10 minutes to end proceedings. Robert Addo Sowah barged into Ahmed Toure inside the box as the striker tried to reach a through ball.
The referee quickly pointed to the spot, much to the admiration of Medeama fans at the T & A stadium. Atinga, the penalty specialist, calmly beat goalkeeper Richmond Ayi.
Hearts finished the game with 10 men as Kwadwo Obeng Junior was sent off in stoppage time.
