ROCKS came from behind to pick up a fine win at Ram Meadow.
That made it back-to-back league wins for John Coventry's side and moved them up to 11th in the Ryman Premier table.
After a goalless first-half, John Sands fired the hosts into the lead on 51 minutes after some neat approach play.
Rocks defender Simon Peddie was booked as he led the protests for what they felt was an offside goal.
But they were level six minutes later as some great skill from David Bryant allowed Liam Burgess to smash the ball home.
Then Bryant set up substitute Kye Ruel in the 71st minute to lob keeper Marcus Garnham for the winner.
East Thurrock: Justham, Sammons, Stephen, Peddie, Wood, Parmenter, Burgess, Gilbey, Menga, Bryant, Collins.
Echo MOM: Kye Ruel (East Thurrock).
