Chris Dagnall scored twice as Barnsley secured safe passage into the quarter-finals of the FA Cup by seeing off 10-man MK Dons 3-1 on Saturday afternoon.
First-half goals from Dagnall and Marlon Harewood ensured the tie went with the form book, with Dagnall adding a third late on as David Flitcroft's Tykes clinched their seventh win in their last eight matches.
The 2008 FA Cup semi-finalists survived a spirited second-half fightback from MK Dons, who pulled a goal back through Dean Bowditch but could not make further inroads.
It did not take long for Barnsley to take control as Dagnall - scorer of the only goal in the fourth-round win at Hull - latched onto Jacob Mellis' pass and fired an angled shot across David Martin with just 144 seconds on the clock.
The former Scunthorpe striker then had a good opportunity to double his tally but powered an effort over Martin's bar after easily springing the Dons' offside trap.
Harewood, an FA Cup runner-up in 2006 with West Ham, added the second goal after 19 minutes, side-footing home after being picked out inside the area by Scott Wiseman's clever cut-back.
The game was halted for seven minutes following a clash of heads between Kelvin Etuhu and Adam Chicksen, which left the former requiring medical attention before being carried off on a stretcher.
The stoppage did not derail the Dons' lively start to the second half, and they halved the deficit through Bowditch just after the hour mark. The 26-year-old striker kept his cool to slot past Luke Steele when he found himself one-on-one with the Barnsley goalkeeper to give Karl Robinson's side renewed hope.
Referee Michael Jones added 12 minutes of stoppage time following Etuhu's injury, and Dagnall did not take long to put the result beyond doubt as he rounded Martin to finish off any hopes of a dramatic revival from the Dons.
Alan Smith was then sent off for raising an arm against Rory Delap as Barnsley saw out the remainder of stoppage time to advance.
