Dave Woods, BBC Two commentator
Jonathan Davies says the sidestep was "Jason Robinson-esque". Not too sure about that, but that was an unbelievable try for a 37-year-old prop to score.

20:50Quote MessageKeiron Cunningham (St Helens head coach) will be saying it's only 12-4, and given the onslaught from Leeds at the start, it's not a bad return.

39 minsQuote MessageAny kid watching - when you run the ball with two hands, you keep the defenders guessing. Adam Quinlan was brilliant, he kept the defenders away from him and sent Mark Percival over. St Helens have been on the ropes, but back they come. They'll go into half-time with momentum on their side.

Quote MessageIt will be really tight. A drop-goal either way might settle this. They're two fabulous teams. It might be the bounce of the ball, it might be a referee's decision or a bit of ill-discipline that separates these two teams tonight.

Quote MessageIt's been a really vibrant competition. The performances of teams like Leigh Centurions has done that, taking the scalps of two Super League teams. Not just that - the manner of how they did that, playing an attractive brand of rugby.
