The victory assures England of a place in the semifinals.
Wales was the better side in the first half, capitalising almost immediately when English defender Ollie WILLARS was sin-binned for five minutes.
Captain Luke HAWKER (WAL) deflected home a brilliant pass into the circle to give the underdog a 1-0 lead.
After the break, England returned to the field a changed side, with WARD scoring his first goal after a sustained period of attacking play.
The team continued to press for an equaliser and with 12 minutes remaining, WARD scored again, this time firing home a brilliant penalty corner flick.
Wales did its best to hang on, but with just three minutes left the prolific forward scored the winner.
