Jon Underwood described it as ‘the complete away performance’ from his side, as first half goals from Warren Harris and Perry Coles were added to in the second half by Harrison Gilkes – who netted his first for the club following his injury woes – and James Dobson late on, as Slough made it nine points in just six days.
The result means the Rebels have now reached the 80-point mark, and eight points from their remaining seven matches will realistically be sufficient to guarantee at least a fifth-place finish.
Predictably, having played twice over the Easter weekend, Slough made several changes – most notably in attack, with Mark Nisbet utilised as a striker to support Coles – whilst Josh Jackman and Nathan Smart came in to replace George Wells and Scott Davies.
Slough won a series of early corners, and Matt Day saw a header tipped over the bar by Kyle Phillips.
Lee Togwell was later denied by a great defensive block by George Miller, whilst at the other end Jackman slid in to block Joe Raynes.
Jon Davies fired a free kick over the bar after Raynes had been brought down just outside the area, but neither side created a clear opening in the opening half an hour, with both getting to grips with the wet, heavy pitch.
A good spell for the hosts ended with Josh Brace sending in a shot with Jack Turner dealt with comfortably.
Minutes later, Slough had the lead in spectacular fashion with Warren Harris on target again. After his superb strike at St Ives a few weeks earlier, the winger again took aim and struck from outside the box, with the ball going in via a post.
Three minutes later, the lead was doubled as Coles struck hard and low across Phillips from just inside the box as Frome failed to clear.
Dobson had a chance to make it three on the stroke of half time, but Ollie Knowles blocked his shot.
Slough applied heavy pressure early in the second half, but needed Turner to be at his best on 54 minutes to maintain their two goal lead. Davies crossed in for Raynes, whose header looked destined for the top corner but Turner had other ideas, diving full length to claw the ball clear with a stunning save.
The Rebels looked increasingly comfortable with their lead as the game wore on, and the result was all but confirmed when substitute Gilkes added a third goal on 83 minutes, finishing after Manny Williams had an effort blocked – his first for the club in only his sixth appearance after a long time on the sidelines with an ACL injury sustained in the summer of 2016.
Four minutes later, Slough surged forward again and this time Gilkes turned provider, crossing in low for Dobson to finish from close range.
