Reading's under-21s suffered only their second defeat in since October as West Ham United ran out 2-0 winners at the Camrose on Monday night.
Our youngsters went into the game on the back of four wins in five, but were unable to breakdown a resolute and clinic Irons side.
The Royals and the Hammers played out a fairly uneventful first 45 minutes - with Reading's best chance coming in a frantic goalmouth scramble, with Craig Tanner involved as the visitors cleared off the line.
But on the stroke of half time, the Londoners were ahead - and in stunning fashion. Son of former England international Rob Lee, Elliot Lee caught an aerial through ball on the volley first time, and it sailed past the hapless Dan Lincoln into the top corner.
Reading improved after the break and went very close to equalising when substitute Liam Kelly struck the post from distance.
But it was to be the visitors' night, as Hammers midfielder Blair Turgott tapped in late on to seal all three points.
