Barnsley lead Charlton Athletic after a strong first-half performance in the Championship at Oakwell on Saturday.
The Tykes almost took the lead when a mistake by Michael Morrison freed Chris Dagnall, but Ben Hamer made himself big to keep his effort out.
After a good opening spell, Barnsley did take the lead after 16 minutes when Scott Golbourne fired a dangerous ball into the Charlton box, which was missed by Chris Dagnall but was bundled in by Chris O'Grady.
David Flitcroft's side continued to create chances and, but for the resistance of Hamer in the Addicks' goal, could easily have doubled their advantage.
However, Barnsley were forced to bring on Kelvin Etuhu after midfielder David Perkins picked up an injury.
The Yorkshire club are without a league win so far this season, while Charlton will be looking to bounce back from a 1-0 defeat at home to Middlesbrough.
