Barnsley manager Danny Wilson praised his side's game-plan after they beat Oldham Athletic 1-0 following an early goal from Kane Hemmings.
Oldham threatened in the opening stages with Jonathan Forte chipping over the bar and Mike Jones sending a long-range effort wide.Hemmings struck in the 12th minute, finding the net with an impressive finish after meeting a right-wing cross from Milan Lalkovic with a near-post volley.
Barnsley made an unsuccessful appeal for a penalty when Lalkovic went down in the area under a challenge from Joseph Mills.
Wilson said: "They're a good side with some good players in there and they play a certain way but I think we frustrated them a great deal.
"They like to play in the middle of the park and we didn't allow them to do that. We forced them wide and we're strong in those areas.
"I thought it was a real incisive and quick move that got us the goal.
"I thought we showed great resilience in the last two games by going in front and being able to hold the lead.
"Defensively, we have been outstanding in the last two games and that has given us that platform. As a team performance I thought it was excellent.
"It was an absolute stonewall penalty and I don't even have to look at it again, although I have. Milan has got great acceleration away from Mills and he just can't get to the ball.
"The referee obviously thinks the full-back has made contact with the ball but he was nowhere near it. Thankfully it didn't have an impact on the result."
