There was much delight in the Ospreys camp as they snatched their second RaboDirect PRO12 title in three years thanks to Shane Williams' late converted try in a 31-30 victory over Leinster.
Williams was thrilled to be retiring on a winning note after his 15-year professional career ended with a two-try haul which inspired the Ospreys to a record fourth league success.
"I enjoy success of course like anybody else. The one you remember is the latest one and this for me is a great way for me to finish," admitted the 35-year-old winger.
"I am very proud of the fact that I am associated with the Ospreys. We have worked very hard this season, we have had our ups and downs and there has been a lot of change in the ranks, with a lot of players leaving the region.
"For us to stick at it the way we have this season it's a compliment to the guys. I will never forget this day."
The victory seemed to be getting away from the Ospreys when Heineken Cup champions Leinster took a 17-9 half-time lead and Isa Nacewa's second try then pushed them 30-21 in front.
But the Welsh outfit, who finished second in the table, bounced back superbly to stun the RDS crowd with a 10-point spurt in the final 10 minutes.
They had done the double over both Leinster and Munster during the regular season and beat the Irish pair in the play-offs, coming to the boil at just the right time.
It was young out-half Dan Biggar who took on the mantle of match-winner as having already kicked 14 points, he coolly converted Williams' 78th-minute try to edge the Ospreys home.
Their head coach Steve Tandy praised his players' character and fighting spirit to hold out until the final whistle despite Leinster threatening to hit back in injury-time.
"I think it is testament to the team - the whole group and backroom staff and everyone involved in the organisation, but especially the team," he said afterwards.
"The team have been fantastic since I have taken over and in fairness the boys were relentless.
"We probably thought we were out of the game today, but the guys dug deep. Some things were a bit frantic out there, but we stuck with what we were trying to achieve.
"I think it is great for the Ospreys and what a great way to finish the season."
Leinster head coach Joe Schmidt was understandably disappointed by the manner of the defeat which came just eight days after they retained the Heineken Cup.
Yellow cards for Heinke van der Merwe and Nathan White, along with an early injury to fellow prop Mike Ross, hampered the Irish province as they fell to their third successive league final defeat.
"I am pretty gutted obviously. We knew that it was going to be tough and we had to be in front in the back half of the game," said Schmidt.
"There was going to be a little bit of fatigue, and I think you get more fatigue when you are down to 14 men twice in the half.
"That means you have to overwork a little bit. We fell off a couple of tight tackles and maybe just didn't have things bounce our way.
"I thought it was a superb kick by Dan Biggar from the edge and it was pretty much the same thing he did to us last time to get a one-point win (here back in March)."
