Albion were beaten 2-1 by Burnley at Turf Moor on Friday night.
The Baggies found themselves ahead at half-time thanks to Darnell Furlong’s early opener.
However, the hosts came back in the second period to snatch the Sky Bet Championship points via Nathan Tella and Scott Twine efforts.
The boss made one alteration to his XI as Grady Diangana replaced the injured Matty Phillips. There also appeared to be a formation change to try and cause the league-leaders trouble.
It was Albion who made a flying start in Lancashire, Furlong getting up the highest to meet John Swift’s corner and hammer a header in after just seven minutes.
The home team attempted to hit back and saw two penalty shouts waved away before Alex Palmer was tested – the goalkeeper reacting brilliantly to deny Erik Pieters from accidentally netting following a dangerous low cross.
The teams then exchanged disallowed goals ahead of half-time. First Okay Yoluslu had one chalked off for fouling Arijanet Muric, and down the other end Ashley Barnes’ volley was called back for offside.
Burnley had a golden chance with the interval seconds away, too, but Barnes’ effort 10-yards out crashed against the crossbar.
Opportunities continued to fall the way of the Clarets in the second period, yet brave defending by Furlong and Okay Yokuslu twice denied Anass Zaroury curlers.
Their leveller did eventually arrive, though, thanks to Tella – the attacker racing forward and finishing past Palmer.
And substitute Twine got their winner, directing a free-kick towards the top corner a few minutes from time.
Albion: Palmer; Furlong, O’Shea, Pieters, Townsend; Diangana (Reach 83), Molumby (Grant 89), Yokuslu, Swift (Rogic 67); Wallace, Dike.
Substitutes: Button, Ajayi, Gardner-Hickman, Livermore.
