Albion's PL2 side fell to a derby day defeat against Aston Villa at The Hawthorns on Friday evening.
Richard Beale's side were made to pay for slow starts in both halves as their local rivals struck early on in each 45 to claim the spoils, a result which sees Villa close the gap between the sides to two points in the PL2 Division Two table.
The visitors struck within the first five minutes through Tommi O'Reilly, as the youngster found space on the edge of the box before firing an attempt at goal which Albion goalkeeper Josh Griffiths couldn't keep out.
It didn't take long for a second goal to come, and once again it was in the visitors' favour, O'Reilly turning creator to cut back and find Brad Young who made no mistake from ten yards out.
Villa continued to threaten the Albion goal, with Young seeing two efforts well blocked before Declan Frith found the side netting with a low strike as the Baggies struggled to get a foothold.
Kyle Bartley, working his way back toward first-team action from injury, stood firm to block two goal-bound efforts as the visitors continued to push for another.
Arjan Raikhy then should have added to Villa's first half advantage when played in on-goal, but he fired a low effort inches wide of the post before seeing another strike well saved by Griffiths just ahead of the break.
The second period started in a similar vein to the first, with Griffiths on hand to save one-on-one as the visitors looked for a third.
However, Griffiths could do nothing about the next effort from Raikhy, who was found with time and space in the area before picking out the bottom corner with a curling effort to get his name on the scoresheet.
Albion responded and soon saw their best chance of the evening come their way. Akeel Higgins turned in the box and looked certain to hit the back of the net, but his effort was just inches wide of the post.
It wasn't to be their evening though, and Villa found their fourth goal just ahead of the hour mark, with Young finishing off a quick counter with a powerful finish.
The Baggies had Griffiths to thank once again soon after, as he tipped what looked to be another strike destined to find the back of the net onto the post before clearing.
Albion pushed for a consolation as the half wore out, but it was not to be for Beale's youngsters as the visitors saw out the last 20 minutes to claim victory.
