Ross Byrne marked his 22nd birthday with one of the sweetest strikes you'll ever see as he drop-kicked Leinster to a huge victory over the Ospreys in Wales.
Byrne's 80th minute drop goal looked set to keep Leinster top, but in a three-minute spell of pulsating PRO12 drama, the young fly-half then conceded a penalty for a high tackle, gifting Ospreys and Wales 10 Dan Biggar with the opportunity to snatch the game at the death.
Biggar, however, sliced a relatively straightforward kick wide right of the posts, leaving the Swansea side to contend with a 20-18 bonus point defeat.
The result provides a significant boost to both Leinster and Munster's chances of home semi-finals, with Leinster moving nine clear of the Welsh side and Munster remaining three clear with this weekend's game in hand.
