Medeama SC applied brakes on Aduana Stars after pipping them 1-0 at the Akoon Park in the Ghana Premier League on Sunday afternoon.
Burkina-Ivorian Amed Toure left it late to score the winner for the Mauve and Yellows who recorded just their fourth win of the season.
None of the last five encounters between the two sides has ever ended in a draw with either side winning their home games.
Aduana trekked to Tarkwa having won just once in their previous 9 visits and the results from the outcome of Sunday’s game spells a decisive end to Aduana Stars’ 6-game winning spree.
The Fire Boys had amassed 18 points from their last 6 games and a victory would have shot them to the summit of the league table.
