WASPS boss Dai Young has lauded Joe Simpson after he scored a try that Young believes no other scrum half in England could have scored.

It was a moment that turned a game, calling on Simpson's deadly eye for a gap and the breathtaking pace to exploit it.

London Welsh were leading Wasps 12-9 and looking healthy 49 minutes into their Aviva Premiership match at the Kassam Stadium yesterday.

They'd won a line-out on half-way and their entire backline fanned out across the field.

But the ball went loose and when Simpson pounced he had only one thought in his mind.

Less than 20 seconds later he'd broken past the lot of them and gone over on the opposite side of the field.

It ignited his team and they ran in three more tries to swamp their hosts and win 34-15.

Young said: “That was the turning point in the game. It was scored right at the time that we needed to score. “If they had scored or got another penalty we could have been into a real nail-biter.”

Simpson's try took the score from 12-9 to Welsh to 14-12 to Wasps.

Young said: “It was a fantastic solo effort. I don't see many other scrum halves scoring that. He's got real wheels when you put him into that kind of space and he found a way to score and did really well to get to the line.”

For Simpson, the try continued a superb individual season after his career appeared to stall for a few years as he struggled to influence matches from behind a fragile Wasps pack.

However, he's learned from that experience and on top of the match-winning instincts he has added maturity and control.

Young said: “He's not lacking much as rugby player. He's pretty much got everything in his locker. He hasn't let us down at all this season and has been outstanding.

“His kicking game has been as good if not better than any other scrum half in the Premiership, his service is as good, he's making the right decisions for us week in and week out and if you're looking for somebody that's going to create something out of nothing there's not many better.

“I'm really pleased with him and wouldn't swap him for anyone else. I think he's getting better and better with every game.”
