"Up front, we're really starting to come together," the 6-foot-3, 260-pound Kerrigan said. "We're gaining confidence with each week."
On 39 carries, Wade, a senior tailback, broke the single-game mark of 243 yards set last year by Jamal Abdur-Rahman, now at Villanova.
"I don't think we were planning to run the ball that much," Kerrigan said. "But when Timmy gets going, it's hard to turn away from him and throw the ball."
Next weekend at Northeast, on a day and time to be determined, La Salle will play the winner of Saturday afternoon's semifinal between Roman Catholic and St. Joseph's Prep.
The Explorers line also included tackles Dan Wasylenko and Matt Maginnis, guards Patrick Hoffman and Tom Spiteri, and tight ends Mike Piscopo and Chris Kane. Luke Persichetti filled in at guard after Spiteri was injured in the second quarter.
Kerrigan, who throws the shot put in track and field, is considering playing football at Lycoming, Susquehanna, or Lafayette. He was a part-time contributor in last year's drive to the PIAA state final.
The Crusaders were without standout two-way lineman Eric Condron, a 6-1, 240-pound senior captain who injured his right knee in last week's regular-season finale against Archbishop Ryan.
Just two plays in, Judge grabbed a 6-0 lead on a 72-yard touchdown jaunt by Raul Quinones.
La Salle answered with a 22-yard field goal from Ryan Winslow and a pair of TDs: a 2-yard dive by Wade and a 19-yard connection between Matt Magarity and Colin Buckley on a right-side fade late in the second quarter.
Wade, who rushed 18 times for 145 yards in the first half, received extra work after Jared Herrmann was lost to an apparent right-ankle injury in the early going.
John Palermo, whose 35-yard TD burst in the third quarter made it 23-9, and Colin O'Hara helped fill the void.
