GIANTS livewire Sean Penkywicz is looking for a repeat performance against Castleford in tomorrow's big Super League IX opener at the McAlpine (3.00).

The 21-year-old former Halifax hooker was the star of the show as Huddersfield destroyed the Tigers 36-0 in the McAlpine pre-season clash three weeks ago.

He proved almost unstoppable with his numerous darts from dummy half, and matched that with a solid defensive effort in which a big `hit' on Castleford prop Craig Greenhill was the highlight.

But Penkywicz knows tomorrow will be far harder.

"I couldn't have asked for a better start," reflected the pocket battleship.

"You always hope to make a solid start at your new club, but I honestly didn't think it would go as well as it did that night.

"I couldn't believe how much space I was given around the ruck, not that I was complaining!

"I know there's no way I'll be allowed that sort of luxury tomorrow.

"Castleford were clearly in pre-season mode that night and we made them suffer for it.

"They will know what to expect from me when it comes from runs from dummy half, and I'm sure they'll be looking to shut me down as quickly as possible.

"But there's far more to my game than that, and while we know Castleford will have more to offer, we'll also have far more up our sleeves.

"What we see tomorrow will be poles apart from three weeks ago, we'll all fully aware of that fact."

Penkywicz's debut display proved he has wasted little time fitting into his new environment.

The new recruit checked in for pre-season training a week ahead of the rest of the Giants squad, and believes that has been beneficial.

"I felt really at home from day one. The set-up's very professional and the staff are fantastic" he added.

"The training has been exceptionally hard, but very enjoyable. I feel fitter than I ever have.

"The key now is to make sure we transfer all our hard work into a good quality Super League performance.

"There's no reason why that can't be achieved, starting tomorrow."
