Warrington have given new contracts to academy products Ben Harrison, Steve Pickersgill, Chris Riley and Mike Cooper, who have all played in Super League this year.

Second row forward Harrison, 19, has signed a new three-year deal keeping him at the Wolves until the end of the 2010 season.

"I have been part of this club since my schooldays and I never considered going anywhere else," he said.

Prop Pickersgill, 21, has signed a new 12-month deal, while winger Riley, 19, and prop Cooper, 18, have taken up one-year options on their current contracts.

Coach Paul Cullen, who last month secured the futures of two other local youngsters Kevin Penny and Andy Bracek, said: "It's essential as a club we continue to produce talent of this quality.

"Ben, Steve, Chris and Mike have the attributes to go to the very top in this game. The investment in our academy system is now paying dividends for us."
