Orlando Engelaar maintained Melbourne Heart's late-season revival, scoring the only goal in their 1-nil defeat of A-League football leaders the Brisbane Roar.
For an hour, it looked as though the league's form team and best team would cancel themselves out but Engelaar's intervention ensured Heart would meet Melbourne Victory in next week's derby on a winning note.
Despite the loss Brisbane still sit atop the A-league ladder four points clear of the Western Sydney Wanderers.
The Heart remain rooted to the bottom of the table, though their now equal on points with the Perth Glory.
The Wellington Phoenix are 7th, one point outside the top six playoff spots.
