The Development Squad continued their hot streak with a 2-0 win against Norwich City in Friday night courtesy of a looping header from Rob Hall and a low drive from Pelly Ruddock.
Prior to kick-off at Rush Green the Canaries were level on points at the top of the league with both the Hammers and Arsenal, who themselves had succumbed to defeat at Rush Green just one week ago.
The away side settled the quicker of the two but it didn't take long for Ian Hendon's side to find their rhythm and with eight minutes played they should have taken the lead.
Hall charged down the left on the counter, before leaving three Norwich players in his wake and crossing to the arriving Paul McCallum, who failed to hit the target from five yards.
Just two minutes later Hall showed McCallum how it is done. Matthias Fanimo broke down the left and found Dan Potts on the overlap who floated a cross to the near post where Hall sent a looping header over Declan Rudd.
Jack Powell, who was a late change to the line-up, almost created a second West Ham goal just a minute after their first but captain Callum Driver was denied by the crossbar from 30 yards.
With 20 minutes gone it was still all action as Norwich almost drew level when Driver once again took centre stage by somehow clearing Aaron Tumwa's header off the line with Raphael Spiegel beaten.
64 minutes into the game the Hammers felt they should have been 2-0 up. Potts showed terrific vision, turning his man on the byline before pulling the back to Moncur, who fizzed his shot towards goal. The keeper was beaten and a goal looked certain but, just like Driver in the first half, Norwich had a hero of their own in Ewan McNeil, who stopped the ball dead on the line. Despite the Hammers' claims that the ball was over the line, their protests were waved away.
Norwich continued to struggle and were unable to break down the resolute West Ham United back line and Ruddock secured the points on 90 minutes, turning in the box before firing into the corner past Rudd.
Meanwhile, Blair Turgott was also in action on Friday some 1500 miles away, scoring twice as the England Under-19s ran out 6-0 winners against the Faroe Islands in Tallinn, Estonia.
The Irons youngster was thwarted on two occasions early on by keeper Eli Leifsson, but eventually beat him in the eleventh minute from 20-yards before adding a second and England's fifth with eight minutes remaining.
Arsenal's Chuba Akpom also scored twice with substitutes Hallam Hope and Calum Chambers also on the scoresheet. Next up for Turgott and England is a tie with Ukraine on Monday.
