Ballynahinch's much anticipated introduction to life in the top flight proved to be a harsh baptism as they failed to deliver the hoped for result in front of the Ballymacarn Park faithful.
Instead, the Co Down side had to make do with a losing bonus point on their first day in Division 1A when they went down 24-17 to Cork Constitution who pretty much spoilt the party for Hinch.
Derek Suffern's squad – with Paddy McCallister, David McIlwaine and Kyle McCall bolstering their ranks – just couldn't back up their decent enough start after going 6-0 up from two early Ritchie Lobb penalties and, even though they fought back from being 16-6 down with an Aaron Ferris try, Con proved just too strong.
In Division 1B, Belfast Harlequins also experienced that losing feeling – but painfully without a bonus point – at Deramore as Buccaneers prevailed 29-21 in a clash brimming with drama which saw a hefty 42 points racked up in an action packed second half.
In all, seven tries were run in. Buccs totally dominated the opening half but only led 8-0 at the turnaround. On the resumption Quins struck back with two marvellously taken tries by Ulster second row Neil McComb before full back Euan Strang got on the end of a sweeping Quins attack off a scrum.
Out half Liam Cambridge converted all three which saw Quins score 21 unanswered points to lead 21-8 after 56 minutes and, seemingly, secure the result.
But there was another twist to the unfolding drama as, three minutes after Cambridge converted Strang's score, Buccs' skipper Alex Hayman crossed near the posts.
Carty's conversion made it 21-15 and Buccs were back in the game which six minutes later saw Connacht player Tiernan O'Halloran also touchdown near the sticks which, again, Carty converted.
Cambridge was wide with a penalty chance in the 67th minute – as he had done so earlier when Quins led 14-8 – and Buccs then racked up their own unanswered 21-point total when late on James Tormey smashed over near the uprights for the bonus point score which Carty, yet again, converted.
Afterwards, Quins coach Adam Larkin was philosophical about a game which had frustratingly slipped away.
"We had the chance to turn the knife and we did exactly the opposite. You can't expect to do that and come away with a win," said Larkin.
Over at Gibson Park, Malone prevailed 20-10 in their Ulster derby with Dungannon in a game which was held up for a lengthy period of time due to a serious ankle injury sustained by Gannon full back Mark O'Shea.
After play resumed, following O'Shea's injury, Michael Barker stormed over to deny the visitors a losing bonus.
