Brad Thorn's troops had a splendid start. They went up 5-0 after just two minutes of play, loosehead- prop Jean-Piere Smith bulldozed over the line from the back of a line-out drive.
The Lions had a chance to hit back. However, the visitors failed to retain the five-metre line-out ball and was forced to reconstruct the attack from the 10 metre.
They eventually made some valuable metres, but waisted another try-scoring opportunity when Marx's pass swung forward inside the oppositions' five-metre line.
Instead, the Reds, who starved from possession for a short period of time, went up 10-0 after 10 minutes. No.8 Caleb Timu timed an intercept perfectly and dived over in the corner for the five-pointer.
Flyhalf Hamish Stewart failed to slot over both conversion, however, his brilliant break led to a try from Brandon Paenga-Amosam who powered over the line.

Man of the match: The Reds' pack was remarkable. While the Tongan Thor Tanila Tupou delivered a solid performance, our nod goes to Jean-Pierre Smith. The loose-head prop's work rate was magnificent - on the defence he made 10 tackle, while on attack the big guts made 17 metres and scored a try.
