The game started with both sides right at it amid a good derby atmosphere. Luca Connell shot wide for the hosts before Glenn Middleton fired the game's first attempt on target straight at home stopper Owen Goodman. Jack Senior then glanced a header wide from a corner before the game hit a lull.
David McGoldrick awoke the contest from its slumber as he tried his luck from distance, testing Thimothee Lo-Tutala for the hosts' first effort on target as the sides went in level at the break. Reyes Cleary drilled a shot straight at Lo-Tutala just after the restart as Barnsley came out with much more impetus.
Rovers were then presented with a golden chance to go in front when sub Hakeeb Adelakun - who had only been on the pitch a matter of minutes - was fouled in the box. Up stepped Elliot Lee with a clinical penalty to open the scoring.
Barnsley then rallied but in truth never really looked like equalising. The best they mustered was a shot from ex-loanee Patrick Kelly that was shovelled away well by Lo-Tutala to seal the derby spoils.
Here's how we rated the Rovers players at Oakwell:
5. Jack Senior 7
On the end of a meaty challenge from O'Keeffe early doors. Glanced a header wide from a corner. Defensively was alert, especially against sub Yoganathan. Photo: Howard Roe/AHPIX LTD
6. Robbie Gotts 7
An energetic showing, as is now the norm. Booked second half for a tug on Patrick Kelly but - like at Bolton - it didn't affect him. Was everywhere and fired just over at 1-0. Photo: Howard Roe/AHPIX LTD
7. Owen Bailey 7
Headed over early doors. Skipper was up against ex-Rover Patrick Kelly and had a good battle against him. Helped preserve the win with some brilliant headers and leadership as the game petered out. Photo: Howard Roe/AHPIX LTD
8. Jordan Gibson 6
First league start in over a month. One moment first half where he went to ground and made a good sliding challenge that got the away end in high spirits. In terms of going forward, not a shed-load of involvement. Photo: Howard Roe/AHPIX LTD
