A sublime Jay Harris goal put Wrexham on course for a convincing victory as they kept the pressure on early leaders and Welsh rivals Newport County.
The midfielder produced a moment of sheer brilliance in the 18th minute, blasting an unstoppable shot past Barrow goalkeeper Hurst from all of 35 yards.
Andy Bishop pounced for his second goal in as many games after 71 minutes before substitute Rob Ogleby wrapped things up with an assured 83rd minute strike.
With Stephen Wright succumbing to injury during Saturday’s 2-2 draw with Dartford, and joining fellow defenders Chris Westwood and Mark Creighton on the recovery table, Reds boss Andy Morrell moved Neil Ashton to the centre of defence alongside Martin Riley whilst John Hunt filled in at left-back.
At a bitter Racecourse, the opening exchanges were understandably poor as both sides got to grips with the slick surface following 48 hours of heavy rain.
You might expect an untimely slip or a divot in the grass to play a part in a goal in such conditions but none of those came into play for the breakthrough strike.
After Barrow had failed to properly clear Hunt’s low cross into the box from the right the ball fell to Harris 35 yards from goal. He looked up, took a few steps into the space ahead of him and unleashed a ferocious strike which curled just at the last moment to crash in off the post. The strike was struck so sweetly Barrow stopper Danny Hurst had no chance of stopping it.
With that collector’s item immortalised Harris tried his luck again two minutes later but this time his aim was off as the ball sailed into the stand.
Danny Wright and Andy Bishop both fired shots wide of the target when well placed – albeit too well placed as the offside flag foiled them.
Barrow offered little in reply – Adam Boyes opted for the spectacular, a fluffed overhead kick inside the box despite appearing offside.
Wrexham continued to batter the Barrow goal but, as the rain continued to fall, the wrong decision was made in the final third.
Harris was booked in the early exchanges of the second half as Wrexham contrived to ease up on the pressure.
However, with the pace of Adrian Cieslewicz always a dangerous outlet Wrexham went close to doubling their lead. The Pole danced his way past his marker before sending a beautifully weighted inside pass for Hunt to race onto. His low cross into the box was inviting the finishing touch but the Wrexham attack failed to read it and the ball harmlessly rolled out of play.
Hurst saved well from Joe Clarke after Wright played a clever pass before Richie Baker lashed a shot well wide at the other end, when he really should have tested Mayebi after being afforded plenty of space.
After 71 minutes, Wrexham finally edged further ahead. After Wright was fouled 25 yards from goal Reds skipper Dean Keates’ set-piece hit the wall but span kindly to Bishop. Hurst got a hand to his powerful shot but it wasn’t enough to prevent the ball dropping into the net.
Sean McConville had Mayebi at full stretch as his long-range effort zipped just wide of the post as Barrow desperately tried to get back into the game.
Seven minutes from time two substitutes combined to put the gloss on a well-deserved victory.
Brett Ormerod played a simple ball in to Wright in the box and the bustling striker touched the ball through a gap for Ogleby. He drew the keeper and confidently curled the ball into the net.
