Albion's scholars surprised league high-flyers Fulham by coming out on top in a five-goal thriller at Motspur Park on Saturday afternoon.
Following a run of three straight defeats in all competitions heading into the clash, Leigh Downing's team made the hosts pay when they took the lead through Souleyman Mandey's header on 17 minutes.
The Cottagers evened things out from a short corner thanks to Sam Amissah's back-post header with 26 minutes on the clock, as they eventually made their dominance count.
However, it was the Baggies' U18s who would take the lead in at the interval when their leading talisman Adriel Walker got in on the act once again, latching onto goalkeeper Ben Cisse's forward pass to make it 2-1.
Downing's boys created more breathing room for themselves during the early stages of the second half via their in-form marksman, who converted a penalty - which came as a result of good work between Archie Kirton and Olliie Bostock to win the spot-kick - for his second of the afternoon.
Fulham created some nerves when they netted in the 89th minute, but Albion's scholars held firm to secure a morale-boosting win in the capital.
Albion: Cisse, Maughan, Ojetoro, Quinn, Morrish, Sumnall, Kirton, Mandey (Cherchi 75), Walker (Teesdale 90), Deeming, Bostock.
