Petrit Elbi opened the scoring in the 15th minute and added another four minutes later. Rocks, last season’s beaten finalists, were well below full strength and fell further behind on the half-hour to an overhead kick by Rashid Kamara, who helped Tilbury to lift the trophy in 2009.
Spencer Harrison became the second former Miller in successive games to provide his old club with an own goal in the 65th minute (pictured by Mikey Cartwright, with Aveley's Jay Leader celebrating) and Jordan Cox wrapped it up with a penalty in added time.
