Leicester City’s youngsters fired in two late goals to stave off Albion’s attempt at a comeback on Saturday morning.
Striker Eseosa Sule scored for the Baggies just moments before the break to send them in at the interval with their noses in front.
However, the Foxes found the net three times in four minutes inside the opening 10 minutes of the second period to swing the encounter well and truly in their favour.
Keilan Quinn pulled one back to make it 3-2 in the 79th minute, but, with Leigh Downing’s men pushing for a leveller, the visitors went on to bag another couple of goals and secure all three points.
ALBION: Cisse, Kirton, Morrish, Sumnall (Blackshields), Sears, Mfuamba (Kone), Quinn, Deeming, Walker, Sule, Bostock (Chimeziri).
Subs: Brady, Jenner.
