The Rocks never got going as they put in a lacklustre performance at the Brentwood Centre last night.
It was a bitterly cold evening in front of a sparse crowd and The Rocks never seemed to come to life as Brentwood comfortably contained them.
Brentwood hit the bar early on as they seemed to have the measure of East Thurrock who seemed at times to lack bite.
Brentwood went up in 23 minutes and never looked back.
John Coventry may do a little bit of thinking and regrouping now as the two month push to play offs is not only about points but also about momentum.
