Bridlington 1sts paid the price for a slow start at Yarnbury, as they were beaten 22-10.
The visitors were turned over in their own 22 twice in the first five minutes, with the second occasion resulting in a converted try.
When it happened again shortly afterwards, Yarnbury kicked a penalty and Bridlington found themselves 10-0 down inside seven minutes
They steadied the ship and good work by Gary Stevens, Jimmy Thompson and Otis Floyd gained them some territory, but ill discipline allowed the host to clear their lines.
More good work by Jamie Martin, Ryan Girking and Jack Arthur mounted another Bridlington attack but they managed to lose possesion in vital areas.
They were made to pay on 28 minutes when a great move by the Yarnbury backs saw them score a try in the corner.
Finally, Bridlington managed to open their account when they put together three phases of play and Thompson scored a try out wide, which Arthur converted.
But they were reduced to 14 men soon afterwards, which stopped any momentum before half time.
The second half started evenly until a good run by Stevens earned a penalty which Arthur kicked, to reduce the lead to 15-10. But Yarnbury but the game out of reach with their third try with seven minutes remaining.
Bridlington could have earned a bonus point with the last play of the game but they knocked on close to the line
Bridlington director of rugby Rich Girking said: “They are unbeaten at home for the last 12 months so we talked about clearing our lines and getting off to a good start.
“But we didn’t perform for the first 20 minutes.
“After that we played reasonably good rugby buut didn’t convert our chances.
“We need to be more clinical in both 22s, so we stop giving away silly points and start taking more of our chances.
“I’m disappointed that we didn’t get anything out of the game but we shot ourselves in the foot at crucial times.
“We have to take the positives and look forward.”
