Jack Hamilton fired 10-man Arbroath four points clear in the cinch Championship after hitting the only goal in a 1-0 win against second-placed Kilmarnock.
The part-timers continued their surprise title charge when on-loan Livingston striker Hamilton dispossessed Dylan Tait and drilled a shot from 22 yards which squirmed through Killie goalkeeper Zach Hemming’s hands.
Chances were at a premium on a windy night at Gayfield with Jason Thomson and Daniel MacKay coming close at either end in the first half.
Kyle Lafferty missed a good chance for Killie and they could not claw the goal back after James Craigen was sent off for a lunge on Rory McKenzie with five minutes left.
