Slaven Bilic breathed a huge sigh of relief after watching his side win their first game in nine league games after a comfortable 2-0 victory against bottom side Luton Town.
New signing Callum Robinson saw his cross diverted into his own goal by former Albion trainee Donovan Daniels in the 14th minute as the Baggies started brightly.
The on-loan Sheffield United man linked up well down Albion's left with Filip Krovonic and had Albion's first attempt as he fired straight at Luton 'keeper Simon Sluga.
After Albion's goal, Luton throught they had pulled a goal back on the strike of half time but James Collins' goal was rightly chaulked off for offside.
It was the Baggies who pushed for a second and decisive goal came with 20 minutes remaining. Matt Phillips jinked his way inside and out before sending over a delightful cross that Semi Ayaji turned in with his head under the crossbar.
Robinson stung the palms of Sluga with a long-range effort with Luton rarely threatening as Albion recorded their first clean sheet at The Hawthorns this season.
The victory moved Albion back to the top of the Championship after Wigan's victory against Leeds at Elland Road. Albion remain four points clear of third placed Fulham.
