George Williams requires a new half-back partner as Thomas Leuluai is set to switch to hooker in the absence of Sam Powell due to an ankle injury.
Shorrocks did not play for Wigan at all last season after battling back to fitness from a serious knee injury he suffered in February 2017 and instead played on loan at Salford Red Devils.
However, the 23-year-old has caught the eye of Lam in training and has been included in his 19-man squad for Friday’s game.
“Jake’s been outstanding in pre-season,” Lam said. “He’s been one of the highlights. He’s certainly an option.
“The sad thing about rugby league in this country at the moment is there’s no reserve-grade competition so he hasn’t played any games.”
Wigan have second-rower Joe Greenwood and centre Dan Sarginson back from injury but forward Taulima Tautai starts a three-match ban and wingers Dom Manfredi and Liam Marshall are both sidelined with facial and knee injuries picked up in the defeat by Huddersfield Giants last Friday.
“Dom had his teeth knocked back and one of them broken in half,” Lam said. “He’s also broken the top of his mouth which is not a good thing but it’s an injury that may be only one week.
“Liam Marshall will be out for between two and six weeks and Sam Powell is the same with an ankle sprain.”
Warrington coach Steve Price recalls centre Ryan Atkins in place of Bryson Goodwin, who is facing two weeks out with an ankle injury sustained in the win over Castleford Tigers.
