Albion recorded a fantastic, well-earned 3-0 win at Plymouth Argyle on Tuesday evening.
Goals in a sensational second half from Cedric Kipre, Mikey Johnston and Tom Fellows were enough to grab the Baggies all three Sky Bet Championship points in Devon.
Carlos Corberán’s men - who remain fifth - are back in action this Saturday lunchtime with a trip to Hull City.
The head coach made three changes from Albion’s last outing, bringing in Nathaniel Chalobah, Andi Weimann and Fellows.
And the visitors almost made the perfect start when Alex Mowatt drove forward and shot - seeing his deflected attempt kiss the base of the post.
Adam Randell did strike narrowly wide down the other end for Plymouth, yet it was Corberán’s men who looked more likely to find an opener.
Their best two chances before half-time both fell to Weimann, the attacker first forcing Conor Hazard into a good save after hitting a powerful volley, then watching on as his superb goal-bound volley was cleared by an Argyle defender.
Following that goalless first period, Albion immediately set about trying to force a breakthrough - and it nearly came within two minutes of the restart. Tom Fellows played an excellent through-ball and Weimann raced clear, only to finish inches past the far corner.
They soon went even closer as Chalobah’s lay-off gave Jed Wallace an opportunity to shoot, but his effort crashed against the post and crawled agonisingly across the goal-line.
Finally, though, the opener arrived - and it was via an unlikely source. A dangerous corner caused chaos in the area, eventually enabling Kipre to fire home and put Albion one-up.
The Baggies were in the groove and doubled their advantage 14 minutes from time. Substitute Johnston cut inside, beat a Plymouth player and curled a wonderful effort past Hazard, sparking relief and celebration among the 1,150 travelling supporters.
The scoreline was then rounded-off in stoppage time by Fellows, the young winger converting at close-range after Hazard parried Johnston’s initial shot and securing an impressive result.
