Davis Keillor-Dunn's double condemned Stevenage to a fourth straight away defeat in League One as Barnsley pulled away from the relegation zone with a 3-1 win.
Dan Kemp had halved the deficit after David McGoldrick and Keillor-Dunn put the Reds 2-0 up, but the sought-after Barnsley striker scored his 13th league goal of the season to seal the victory in the second half.
