Albion’s first match of their Premier League Cup campaign ended in a disappointing 3-1 defeat at Peterborough United on Saturday.
Adriel Walker continued his fine form in front of goal by netting the game’s opener from the penalty spot in the first 45.
But the young Baggies were pegged back early in the second period before the hosts added two further strikes late on to seal all three points.
ALBION: Cisse, Nelson (Maughan HT), Sears, Quinn, Dupont, Sumnall, Chimeziri (Cherchi 66), Deeming, Sule, Walker, Bostock (Jenner 78).
Subs: Wilkes, Parmer.
