Albion stormed through to the last-16 of the FA Youth Cup with a convincing 5-1 victory against Queens Park Rangers at The Hawthorns.
Jamie Soule opened Albion's account by cutting into the box and curling a low effort into the corner of the QPR net.
With the Baggies in control, Morgan Rogers went close only to be denied by the crossbar just minutes later when he hit a left-footed shot from outside the area.
However, Albion soon reaped their rewards for their dominance as Rayhaan Tulloch was brought down just after the half-hour mark for a penalty, which he tucked home with a powerful strike.
It would be three for Albion by the break as Soule tapped home an excellent whipped ball from Taylor Gardner-Hickman.
Shortly after half-time, Albion put themselves further ahead as Tulloch burst into the box and hit a left-footed strike underneath the goalkeeper to double his scoring tally.
With just over quarter of an hour to play, Oluwabunmi Babajide gave some hope to the visitors by converting at the near post from a Dillon De Silva cross.
But the Baggies would end the game in style, with Rogers scoring a left-footed shot from outside the box to round off an impressive display at The Hawthorns.
Mike Scott's side will now travel to Arsenal in the FA Youth Cup fifth-round as the Gunners overcame Tottenham Hotspur with a 5-2 victory after extra-time.
ALBION: Griffiths, Gardner-Hickman, Martinez, Delaney, Harmon; Solanke (Taylor 68), Brown; Rogers, Azaz (Barry 76), Tulloch (Asomugha 84); Soule.
