The second half saw more animosity than goalmouth action as players went down at the slightest of touches.
In the end, the Southern Tigers comfortably saw off the game to avenge last week's 3-0 defeat to the same opponents in the Malaysia Cup, and increase their lead at the top of the MSL.
Bang Seung-hwan's 47th winner at the Darul Aman Stadium, meanwhile, was enough for Kedah to condemn Selangor to their fourth consecutive defeat. The defeat also meant the Canaries closed the gap to within a point of the Red Giants, who slumped to their third straight loss in the MSL, following setbacks against Felda and T-Team.
Elsewhere, Penang extended their improved run under new management with a 2-0 victory at Sarawak, Kelantan scored two goals after the hour to beat T-Team 2-0, and a 71st minute Guilherme De Paula penalty gave PDRM FA a 1-0 win against Pahang.
