Albion's youngsters were beaten 4-1 by a strong Arsenal side at the weekend.
The Gunners raced into a 2-0 lead after just 17 minutes, but Fenton Heard did pull one back for the Baggies before the break.
Leigh Downing's group were unable to force their way back into the contest though and the visitors scored twice more after the restart to wrap up the three points.
ALBION: Hudd, Nelson, Mohamed, Olofinjana, Williams, Deeming, Oliver, Kirton, Heard, Hurlock (Sumnall), Walker (Sule).
