GOALS from James Tomkins, Nicky Maynard, Gary O’Neil and Ricardo Vaz te handed West Ham the win on an eventful night at Bloomfield Road.
The away side found themselves 2-0 ahead before Kevin Phillips headed the Seasiders back into the game on the stroke of half-time.
And when West Ham’s keeper Robert Green was sent off on 52 minutes, then replaced by midfielder Henri Lansbury, Ian Holloway’s men looked to be favourites.
But as Pool threw men forward, O’Neil and Vaz Te sealed the win against the run of play.
