Dinnington seconds paid the price for not being able to keep 15 players on the field, as they spent 20 first half minutes a man short and were out of the game against Paviors II by half-time.
With the damage done, the hosts ran out 43-12 winners.
Paviors came on the attack from the first whistle and it took some good defending by Dinnington to prevent an early score.
In the opening minutes of the game both sides were guilty of giving away too many penalties and the referee had to have words with both captains.
However, Dinnington failed to heed his words and 10 minutes later had a player sent to the bin.
Paviors took advantage and piled on the pressure winning a penalty try and a 7-0 lead.
Dinnington caught their hosts out almost straight from the restart as they fielded a kick, ran in back and after working the ball through a few phases put Steve Leitch in under the posts. Connor Brown converted.
Paviors rallied and continued to use their man advantage to put Dinnington under pressure and with 10 minutes of the half to play the visitors had another player binned just as the first one was coming back.
The home side made Dinnington pay scoring twice in fairly quick succession and then, after they too had had a player binned, scored with the last play of the half to go into the break 26-7 ahead.
Dinnington had a man advantage for the opening minutes of the second half but although they went at the home side they could make no in-roads into a solid defence.
Ten minutes into the half, Paviors went further ahead when they moved the ball out to their quick winger who outpaced the defence to score.
Dinnington, with 15 players, were more competitive for much of the second half but could do little to stop Paviors stretching their lead with 15 minutes to go.
Frustratingly for the visitors they then showed themselves how easy it was to score when they moved the ball along the backs from a lineout and put Rob Leivars over in the corner.
It came too late to affect the outcome and Paviors rounded the scoring off after a spell of pressure created a gap in the Dinnington defence for them to score an unconverted try to finish.
