Unstoppable Mason Grady's 'electric' performance has everyone talking

That was the question posed by BBC's Gareth Rhys Owen during Cardiff's dramatic victory over the Stormers. The South African side simply couldn't find an answer. Many others have struggled since the 21-year-old returned from World Cup duty. In the four matches he's played for the Blue and Blacks this season, he's dotted down in every one.

As commentator Sean Holley noted, he's virtually unstoppable right now. "Don't you just love watching Mason Grady play? If we can just harness the talent that boy has got," he said during Friday night's commentary.

"I like the fact he's playing on the wing, he's learning his rugby. Maybe he'll be able to move him to centre. Every time he gets the ball, he's electric. Once you get it to Grady's hands, look at the acceleration on him. They don't want to tackle him."

After the win on Friday night, a team-talk by Tomos Williams in Italy the week before was referenced by both head coach Matt Sherratt and Grady. In it, the Wales scrum-half spoke about the need for the Arms Park side to always have a chip on their shoulder.

For Grady, that doesn't feel like too much of a stretch. At one point midway through the second half, he bounced off two would-be tacklers before the third and fourth Stormer players to the scene managed to bundle him into touch.

However, Grady was well aware that he was causing them more problems than vice versa. A few verbals as he strolled back might just have referenced that.

By that point, his opponents knew all about Grady - although stopping him was another thing.

"We have been underestimated this season," he said afterwards. "As Tomos Williams told us last week, we need to be playing with a chip on our shoulder.

“We showed a lot of character to stick in it after being 14-0 down. We’re a very young team but that showed there is potential to build on this over the next few years – it’s very exciting.

“We’ve lost three, but we could be six from six. It’s always good to be the underdogs and it is a really good environment at the moment."

Cardiff being underestimated is one thing, but there's another axe for Grady to grind. A first World Cup this summer was a valuable learning experience for Grady, but the 92 minutes he managed in France is a slight bone of contention.

The fact he's hit the ground running on his return is seemingly because of that frustration, rather than in spite of it.

“I feel as though I’ve got my mojo back and playing on the wing is giving me a bit more freedom," he added. "When I was younger, I used to hate the fact they played me on the wing, but now I just look at it as an opportunity to have a bit more freedom and do what I’m good at.

“I get involved in more first-phase attack. I’ve been given a licence to get my hands on the ball as much as possible and then do what I want. I’ve always said I’m a centre who can play wing, but I’m happy as to play wherever. Matt (Sherratt) has given me a licence to roam.

“I was frustrated game-time-wise during the World Cup. That motivated me to start well this season. I learned a lot off the senior players, and I improved my rugby knowledge from watching so many games.”

Whether he's a wing or a centre, and it's important to remember he's only on the wing right now due to a spate of injuries at the Arms Park, the thing that has been apparent in recent weeks is how important it is to get the ball in Grady's hands.

Then, it's up to the opposition to work out the answer to that question. Just how do you stop Mason Grady?
