Goals from Bradley Pritchard and Johnnie Jackson have given Charlton Athletic a 2-0 half-time lead over Barnsley at Oakwell.
The visitors got off to the perfect start by taking the lead inside four minutes, when Pritchard slotted home the rebound following Yann Kermorgant's spilt effort.
The Addicks doubled their lead 16 minutes later. Pritchard was again involved before laying it off to Jackson, who dummied his marker before burying the ball into the back of the net.
Jackson nearly made it three shortly after with a dipping effort, but Luke Steele just managed to tip the shot-come-cross over the bar.
Barnsley nearly found a response swiftly after introducing Jason Scotland in place of the injured Tomasz Cywka, but Jacob Mellis's effort was blocked on the line by Rhoys Wiggins.
The hosts came close again moments later, but Bobby Hassell's free header was nodded wide from Tom Kennedy's corner.
