Leeds Carnegie 22
Once again Moseley emerged from a strong half-time coffee with their faculties restored to survey the wreckage of the half before.
Once again they came mightily close to clearing up all of the mess and claiming a precious Championship victory. But once again they narrowly missed out. And agony, upon indignity, upon torture, what a way to miss out.
Tommy Bell's last kick of the game, a penalty from head on and 40m, which rescued Leeds' victory was a dagger through the heart for Mose after their resolute comeback from 13-3 down at the break.
As is their way at the moment Kevin Maggs' men put in a dopey opening 40 minutes. They conceded too many penalties, their set-piece creaked and while they defended with grim determination, in truth they should have been further behind at the midway point.
Only Jacob Rowan managed to find a way across the visitors' line, after 35 minutes by which time sloppy Leeds had left at least a couple of other tries on the pitch as their American prop Mike MacDonald butchered two overlaps.
But credit Moseley for showing the resolve and for hauling themselves back into proceedings.
Ollie Thomas started the tidy up with three points, on Moseley's first incursion into the Leeds 22, just before the interval and sustained the momentum soon after the restart.
He and Bell kept trading penalties right until the end but if anything Mose were more superior in the second half than Leeds had been in the first.
That was once their forwards got stuck in and their centre pairing of Andy Reay and Greg King began to unsettle the hosts with their off-loading.
On the hour the excellent Reay scythed through midfield where he sprung Billy Robinson for a breathtaking try from first phase.
Although Thomas missed the conversion, how that would come back to haunt Moseley, it didn't seem to matter when their pack waded into Carnegie's.
David Lyons, Neil Mason, Chevvy Pennycook and the impressive debutant, Drew Harper, dual registered with Bromsgrove, led the charge.
At 16-11 down and with six minutes to go they opted to punt a kickable penalty into the corner. Up went Lyons, whose impressive return was a massive boost to Mose, on came the drive only to be illegally hauled down for the concession of another penalty and a yellow card. Twice.
With Leeds' front row Phils Nilsen and Swainston in the bin the Mose scrum won a penalty try. Thomas converted and at 18-16 Moseley were on their way.
But seonds later Bell tolled again, after Sam Brown was adjudged to have held on after fielding a grubber kick in his own 22, although the scrum half felt he had not been allowed to return to his feet.
No matter, Thomas made it 22-19 with a brilliant touchline penalty with three minutes on the clock. Leeds were still two men down, they will forever wonder if they should have gone for the corner.
Nevertheless, they had done enough but when they claimed the restart instead of putting the ball behind Leeds they fiddled and fidgeted within kicking range and eventually Craig Voisey went off his feet.
Up stepped Bell and down came Moseley's colours in an epic, if deflating finale.
The one consolation Moseley will have, more than the loss bonus, is yet more evidence they can master most teams in the Championship - providing they learn how to play in the first half the way they do in the second.
