Barnsley fell to a first defeat in four, seen off by a goal in either half at Swansea City.
On a surface rarely seen in the modern game, Valérien Ismaël's side weren't able to battle their way to a result in a game that matched the state of the pitch as the Swans capitalised with two goals from set plays.
Jamal Lowe struck inside two minutes when he latched onto a flick-on inside the six yard box and despite the Reds dominating the first half from then on, they couldn't hit back and saw the hosts double their advantage midway through the second 45 as Victor Adeboyejo unluckily headed into his own goal.
Whilst the Swans certainly started the game brightly and took that early lead, they barely ventured into the Reds' third after the opening 10 minutes, as Ismaël's side wrestled control of proceedings.
The best chances were via set-pieces with Mads Andersen and Michael Sollbauer going close from corners whilst Alex Mowatt saw a stinging free-kick parried away by the goalkeeper.
It could have been worse for the Reds heading into the interval when Jack Walton clattered Yan Dhanda 20 yards from goal but the referee only produced a booking for the Reds' stopper.
HALF-TIME: Swansea 1-0 Barnsley
There was a smarter decision by Walton soon after the break when he came out to thwart Lowe as the forward again beared down on goal. The former Portsmouth man was a real thorn in our side all afternoon.
Adeboyejo joined the fray in the middle stages of the half along with Luke Thomas and George Miller, and the big man got his name on the scoresheet again but on this occasion for the opposition.
Victor's attempted header clear from a near post corner kick flew off his head and into the far corner, deceiving Walton and effectively sealing a disappointing afternoon in Wales.
