FORMER Nadroga utility back Aisea Natoga scored a hat-trick to help Ospreys beat Cardiff Blues 34-9 during their RaboDirect PRO12 competition match last Friday.
The Flying Fijian winger's treble and scores by Ashley Beck and Rhys Webb was enough to help his side secure a spot in the play-offs.
It was their 13th win in a row against their fellow Welsh opposition, while the Blues' winless run on the road in the PRO12 continues.
After the win, Ospreys now sit at fourth position on the points table behind Leinster, Ulster and Munster.
Ospreys were well worth their 17-9 half-time lead, running in three tries with the boot of Gareth Davies being the Blues' only source of points.
Centre Beck was first to get his name on the scoresheet with just 10 minutes gone after good work from fellow Wales' internationals Justin Tipuric and Alun Wyn-Jones.
Dan Biggar added the extras with what proved to be his only successful kick of the first half.
Webb stabbed a smart kick down the narrow side for Natoga to run on and score.
Ospreys continued to stretch the Blues by playing with width, Jeff Hassler impressing with his workrate, but two long-range penalties from Davies cut the deficit to just three points.
Natoga grabbed his second from the combination of brothers Lewis and Davies Sam before completing his hat-trick in the corner, shrugging off Wales winger Alex Cuthbert.
