Dinnington III travelled to Barnsley II a man short after having lent players to their second team and were beaten 27-14.
Ahead of the game both teams came to an agreement to line-up with 14 men.
The open 10 minutes of the game were played in the mud of mid-field before an error by Dinnington, at a line out, allowed Barnsley to break away and take a 5-0 lead.
Dinnington worked their way back and got play into the home half before another error allowed their hosts to breakaway for a 12-0 lead.
Again, Dinnington worked their way back, but this time they controlled their possession better.
Five minutes before half-time they broke from a line out and Oliver Williamson scored under the posts. David Bell converted to leave Barnsley 12-7 ahead at the break with the game in the balance.
The opening 10 minutes of the second half were close as both sides looked to gain the initiative.
However, errors by Dinnington gave Barnsley the opportunities to score twice in quick succession and in the blink of an eye the game had got away from the visitors.
A rally by Dinnington looked promising, but when they failed to find touch with a kick, Barnsley ran the ball back at them, scoring another try to go 27-7 ahead.
At this point, Dinnington started to play some good rugby, but when Harrison Meese crossed under the posts and Bell converted there were only five minutes to play and no time to stage a comeback.
