Albion earned an important 2-0 win against Cardiff City at The Hawthorns on Tuesday night.
Mikey Johnston’s opener inside a minute was added to by Andi Weimann’s late effort, helping the Baggies claim an impressive fifth straight home league victory.
Next-up, Carlos Corberán’s team host Southampton this Friday in B71 (ko 8pm).
The boss made three changes to his starting XI, bringing in Erik Pieters, John Swift and Johnston for Kyle Bartley, Jed Wallace and Andi Weimann.
And it was after just 29 seconds his side found a breakthrough - Johnston, less than a minute into his full debut, sweeping home an excellent Tom Fellows cross.
Albion supporters showed their support for Daryl Dike - who was confirmed to have suffered a ruptured Achilles earlier in the week - in the 12th minute, with the stadium applauding and chanting his name.
The Baggies soon pushed for a second, Cedric Kipre and birthday boy Alex Mowatt both failing to keep efforts on target midway through the period.
Cardiff did try and put the hosts under pressure before the break, but a series of corners and long-range efforts were defended well, and Corberán’s men held onto their one-goal lead when half-time arrived.
And that pattern continued following the restart - substitute Aaron Ramsey posing a threat and nodding across goal and Kion Etete poking a real, close-range opening over.
The gaffer made four quick substitutions to try and turn the tide, with one of those introduced, Jed Wallace, firing a free-kick narrowly off-target.
Yet it was another super sub which grabbed the match-winning second 10 minutes from time. Wallace was set free down the right and his wonderful cross fell to Weimann, the striker making no mistake to put the game away and earn Albion three crucial points.
