George Waring made it four goals in three games and Sam Winnall got his first since November as Barnsley continued their fantastic form with a 3-0 home win over Walsall on Saturday.
The Reds have now won five in a row for the first time in 19 years while the last time they did so without conceding was in 1955.
Barnsley are now seventh and just goal difference is keeping them out of the League One play-off places.
Lee Johnson, who has three wins from three since becoming head coach ten days ago, kept the same team that beat Coventry on Tuesday. New signing Jabo Ibehre started on the bench but fellow Friday arrival Declan John was not in the squad after failing to get international clearance for his move from Cardiff.
Barnsley got the perfect start when, after a quarter of an hour, Waring beat Walsall goalkeeper Richard O'Donnell to a right-wing corner from Conor Hourihane and headed in from two yards out at the near post.
Waring missed a chance to double the lead soon after as he volleyed wide from inside the box but the Reds went in 1-0 up at half-time without having been threatened at all by the visitors.
After the break, the Reds stepped up a level and dominated.
Waring failed to connect with one Hourihane free-kick then headed another over the bar.
Jordy Hiwula almost levelled for the Saddlers on 60 minutes when the Reds defence allow him to reach a long ball but his lob from the edge of the box floated wide.
Waring made it 2-0 on 71 minutes when he picked the ball up on the very left of the box, showed great skill to beat a defender and then fired across the 'keeper into the bottom right corner.
John O'Sullivan fired just over with one 25-yard effort and forced a good save with another.
O'Sullivan then set up the third goal with a good run on the left and pull-back for Winnall who fired in his first since a hamstring injury kept him out for four months.
