Barnsley claimed four of five wins with a 2-1 victory over an exhausted Rotherham in the Sky Bet Championship.
Goals from Cauley Woodrow and Alex Mowatt in the first half saw Valerien Ismael’s side secure victory in the South Yorkshire derby.
Rotherham’s hopes of a first victory over their neighbors since 1982 had been hampered in preparation for the match with a Covid-19 outbreak and a build-up of injuries, meaning they could only name six substitutes.
Among those absent were former Red Angus MacDonald, Matt Crooks and Billy Jones as Rotherham returned to the game after their last two games were postponed.
Rotherham manager Paul Warne said the club risked a points deduction if the game did not go ahead.
They started off best with Kyle Vassell shooting in a weak effort into the near post which Jack Walton had to push behind for a corner.
But Barnsley took the lead after eight minutes in elegant style with Woodrow, whose father once turned out to the Millers, finishing cold after being spotted by Mowatt’s precision pass.
The visitors made two after 15 minutes with another sweeping motion. Woodrow chose Callum Styles who then had the vision to throw Mowatt over the edge of the box and the skipper buckled an unstoppable effort in the far corner.
Rotherham’s response was again to be denied by Walton, with the goalkeeper having to be vigilant as he dived in to stop Freddie Ladapo’s effort.
Michael Smith, Barnsley’s former moneylender, has been signed on for the second half to bolster the hosts’ frontline. Smith quickly caused Barnsley’s rearguard trouble and he forced Walton to make a smart save.
Rotherham regained the upper hand after 57 minutes with Smith rising the highest in power in Dan Barlaser’s flying turn.
The momentum was with Rotherham and Ladapo should have put them on a level playing field, but he flashed his effort away from goal after finding space on the left side of the penalty area.
Victor Adeboyejo should have restored the two-goal advantage at the other end after dismissing Wes Harding but the young striker dragged his effort away. Styles was the next to take a chance, but his efforts from a similar lineup were also out of focus.
Matt Olosunde’s volley from the edge of the box forced Walton to a stop as Rotherham went straight in for a leveler.
The best late chance fell on Barnsley’s path as Styles picked Woodrow on a free kick, but his volley was straight to Viktor Johansson.
