Dagenham 2, Leigh RMI 0: RMI's disappointing season continued as poor finishing saw them slip to their fifth successive defeat.
Dagenham & Redbridge striker Craig Mackail-Smith scored both second-half goals to leave RMI still searching for only their second win of the season.
Another disastrous start to the second half saw Leigh concede a 47th minute goal when Mackail-Smith headed home Glen Southam's left-wing cross.
He rifled home the clincher - his fifth goal in five games - from inside the penalty area on 75 minutes, to seal a comfortable win.
Manager Phil Starbuck remained upbeat that his side can pull themselves out of the bad run of results.
He said: "The first half was a stalemate and we had a great chance when Karl Rose went round the goalkeeper but he took it too far and the full-back cleared his shot off the line.
"The first 10 minutes of the second half was not our best but the goal was a comedy of errors.
"It should have been a foul and then the goalkeeper slipped. It seems nothing is going for us.
"We changed the formation to 4-4-2 and created six or seven chances, but we hit the crossbar and the keeper made some great saves.
"It is a game we should have won. I can't fault the lads for their effort but it is so close and yet so far. We need the breaks to go our way.
"If we keep working hard and performing like that we will be okay. I am going to bring a couple more players in and as soon as we start taking these chances we will start winning games."
