Three quick-fire goals helped Crystal Palace condemn Albion's Under-18s to defeat at their Walsall training ground on Saturday afternoon.
Following a goalless first 45, things came to life for the Eagles after the break.
Victor Akinwale bagged himself a brace, either side of substitute David Obou's effort, to give the visitors a 3-0 lead in the space of nine second-half minutes, providing the young Baggies with more important lessons to learn from in their development at the club going forward.
Albion: Cisse; Williams, Machisa, Olofinjana, Shaw; Whitwell, Trialist (Oliver 70); Hurlock (Okoka 70), Heard, Higgins (Oluwatobi 76); Love.
Substitutes: Hollingshead, Phillips.
