Sydney Roosters have won their maiden National Youth Competition premiership with a stunning come from behind 30-28 victory over Penrith Panthers at ANZ Stadium.

For all intensive purposes the Panthers looked headed towards a third title when they led at half-time 28-6.  It was a solid first half effort led by Corey Waddell and captain Oliver Clark where their side crossed the stripe five times to set up a big lead.

This combined with Victor Radley being in the sheds under the concussion test and a game ending shoulder problem to hooker Grant Garvey made the Roosters comeback even more special.  No other side in the history of Grand Finals in this competition had come back from such a deficit.

The comeback was led by Roosters captain and Jack Gibson Medal winner Nat Butcher who was superb and Radley who fired up after spending time off the field in the first half.

With seven minutes to go the mission was complete as Johnny Tuivasa-Sheck ran down the right hand touchline to score next to the posts and give Jesse Marschke an easy conversion.

Sydney Roosters overcame massive losses to Penrith during the regular season to snatch the game that counted and in doing so making history on the big stage at ANZ Stadium.
