A thumping second half strike from Adam Armstrong helped Rovers to a fourth successive Championship victory, this time against Derby County.
Armstrong crashed home a terrific effort midway through the second half and that was enough to secure all three points against The Rams.
It was a deserved victory for the hosts, who picked up a second successive home clean sheet and move to within one point of the play-offs.
The boss named another unchanged team as his Rovers side look to record a fourth successive Championship victory.
Opponents Derby named a side that included former Rovers loanee Tom Lawrence, who appeared 23 times for the club during the 2015-16 campaign.
A strong start from Rovers saw Bradley Dack come close to opening the scoring inside the opening three minutes, but the playmaker fired wide from an acute angle after being picked out in the box by Corry Evans.
The closest The Rams came to scoring inside the opening 25 minutes was when Poland international Krystian Bielik blazed over the upright from 20 yards out.
Soon after and the in form Dack curled a couple of inches over Ben Hamer's goal after being teed up by Ryan Nyambe.
There were nine minutes left of the first half when Danny Graham had an effort, but his near post attempt from a Stewart Downing corner was flicked into the side-netting.
Armstrong fluffed a glorious chance to break the deadlock with seconds of the half remaining, but Hamer did well to save the low strike with his feet.
That meant the sides went into the interval level, but the visitors were inches away from an opener 10 minutes into the second half when Bielik smashed just past Walton's right-hand post from the edge of the box.
Just a minute later though and Rovers did earn themselves a deserved goal for their display thanks to Armstrong's thunderous effort.
The 22-year-old controlled Evans' excellent pass before rifling a poweful effort beyond Hamer and in for a Goal of the Season contender.
In search of a second successive home clean sheet, Rovers were standing firm as Phillip Cocu threw caution to the wind late on by bringing Chris Martin and Jack Marriott into the game.
Sam Gallagher had come on for Graham on the hour and he nearly set up Armstrong for his and the hosts' second of the game with six minutes remaining, with only a deflection denying the diminutive frontman from sealing the victory.
Mowbray's men were still looking to kill the game off, but Dack couldn't add to his 10 goals this season after bursting in from the right, with Hamer in the way to stop his shot.
A late Marriott header didn't test Walton before the goalkeeper beat away a snapshot from the same player as Rovers managed to see the game out fairly comfortably and continue our fine form.
