Shane Williams scored a sensational late double in his final club game and Dan Biggar added a touchline conversion to hand the Ospreys the RaboDirect PRO12 title with a 31-30 win over Leinster at the RDS.

Change was afoot from the outset of the competition's 11th season with a new title sponsor in the shape of RaboDirect, a new competition name, and a plethora of young stars from all 12 teams emerging throughout the season.
After a season of upheaval at the Ospreys, new coach Steve Tandy sparked a wave of momentum that the Swansea-based region rode all the way to the final, losing only 2 games from their last 8.
A destruction of Munster followed in the Play-Offs and only Leinster stood between them and victory. The Irish had eliminated Glasgow Warriors before winning the European Cup and came close to securing the double, losing by a single point in the inaugural RaboDirect PRO12 Final.
Ospreys won the competition for the 4th time, winnng 31-30, thanks to a late Shane Williams try, converted by a rejuvenated Dan Biggar.
