Rotherham slumped to a 1-0 home loss to Burton - a fourth successive defeat that drops them further off the promotion pace.
Albion made the best of starts with a goal after just eight minutes. Justin Richards skinned Rotherham for pace down the right, slipped a pass wide to Cleveland Taylor and Richards continued his run to turn in Taylor's drive from close range.
And the visitors could have had a second after 20 minutes but Billy Kee's goal-bound shot from Taylor's corner was deflected wide.
Rotherham struggled going forward, but a clever short corner after 21 minutes by Danny Schofield nearly produced a goal when Ben Pringle slipped the ball back to Schofield and his shot was touched over the bar by Ross Atkins.
But the home side's best chance came after 34 minutes when Pringle headed down Schofield's cross only for Lewis Grabban to sky his shot high over the bar.
Grabban almost made amends four minutes after the re-start but his shot hit the bar and went over.
And his effort sparked a Rotherham revival. Alex Revell's header was scrambled clear by Atkins and Atkins followed that up with two magnificent saves to deny substitutes Marcus Marshall and Gareth Evans.
But some resolute defending by Albion, who readily pulled everyone back, saw them through.
