Albion suffered defeat in their West Midlands derby against Aston Villa on Tuesday afternoon at Bodymoor Heath.
Although Aurio Teixeira had given Peter Gilbert's side an early lead, Ben Young's brace and Carney Chukwuemeka's effort saw Villa seize the initiative in the first half - although Jamie Andrews did get a goal back for the Baggies just before the interval.
The young Baggies started the second 45 well and were handed a man advantage when home keeper Filip Marshall was dismissed just six minutes into the half.
Rico Richards seized on Albion's numerical superiority as he netted a quick-fire double to give Albion a 4-3 lead.
But Villa rallied in the space of six second-half minutes as Young completed his hat-trick before netting his fourth and Villa's fifth, leaving Louie Barry to net Villa's sixth goal which secured all three points for the home side.
