In the matchday 18 games, the two-time Ghana Premier League were hosted at the Accra Sports Stadium on Sunday.
However, Isaac Mintah scored a brace as the Dormaa-based side left the capital with all three points.
The win mean Aduana Stars have extended their lead on the league log.
Speaking in an interview after the game, Fabin applauded the performance of his players stating they listened to the instructions he gave and added this is their best game of the season. He said;
“The boys did well. I told you if they play to the things that we’ve rehearsed at training. It will be difficult for Hearts of Oak to beat us and they played to the instructions so things worked for us.
“I think this is our best performance so far this season,” the former Asante Kotoko coach added.
Aduana Stars will host King Faisal on Wednesday in matchday 19 games at the Nana Aggyemang Badu Park in Dormaa.
