Barnsley’s young and energetic side proved too strong in the end for ten-man Yeovil.
The rock-bottom visitors ran out of steam in the second half, on a day when playing with a man for 65 minutes proved just too much.
Debutant George Waring and Conor Hourihane - from the spot - registered for the Reds in the second period on what, in the end, turned into a hugely satisfactory win.
After Waring’s opening strike, sub George Williams lashed inches over with an ambitious effort from 25 yards, while Hourihane’s volley was blocked as it appeared destined for the top corner.
Hourihane doubled the Reds’ lead after 75 minutes. Following a sweeping move down the Yeovil left, the barn-storming midfielder was tripped as he tried to round keeper Steer, and duly stepped up to slot home the resultant spot-kick.
The Reds were now home and hosed, and will be full of confidence ahead of next weekend’s derby trip to Doncaster Rovers.
