Well, that escalated quickly.
Rassie Erasmus' Munster were blown out of the water by a slick Scarlets side that recorded their second victory in Dublin in just over a week having dispatched of Leinster in the semis.
The tone was set early on as Scarlets blitzed into 29-3 lead after just 30 minutes, and there was to be no comeback as the Welsh side kept their foot on the gas throughout. The final score was 22-46, with Irishman Tadhg Beirne even getting himself on the scoresheet.
It must still be said that Munster have had a fantastic season with some incredible moments along the way, but the manner of the defeat, with tries conceded to some very poor defending, left their supporters stunned.
A hard one to take. Certainly not the performance we wanted to give, but thanks for your immense support both today and all season #MUNvSCA

After a phenomenal season it's heartbreaking to see Munster not win any silverware. #MUNvSCA

Scarlets come over to Ireland and beat Leinster and Munster in the space of 8 days. Deserved champions & they did it in style

Nigel hasn't been great today, but far from the reason we're losing. At least this will put the conspiracy talk to bed anyway #MUNvSCA

This performance feeds into the theory that Leinster and Munster mentally checked out after their Champions Cup semi-finals.

Those leaving the stadium right mow aren't real Munster fans.
Stand behind those men on the good days, and on the bad. #SUAF

A really disappointing end to an unbelievably tough season for Munster but they are going in the right direction under Rassie Erasmus.

Magnificent from Scarlets. To beat Leinster and Munster in Dublin is the toughest way to win the Pro12, and they did it in spectacular style

All credit to Scarlets, the fact that both Leinster and Munster believe they played their worst games of the season in the semi-final and indeed the final, suggests that they forced them to do so, rather than it be a co-incidence.
They have had a fantastic turnaround after a poor start, and are fully deserved winners of the Pro 12 title.
