Ryder Kuhns completed 28 of 41 passes for 361 yards and four touchdowns Saturday night and Saint Louis scored the final 22 unanswered points in the fourth quarter to pull away from Kahuku, 45-24, in an interleague showdown at Hawaiian Airlines Field.
The Crusaders improved to 2-0; it was the season opener for the Red Raiders.
The traditional powerhouses traded touchdowns in an exciting first half before a crucial roughing-the-kicker penalty during a Saint Louis punt helped the Crusaders take a 20-14 lead into the locker room. Trailing 14-13 and backed up on its own 15-yard line, Saint Louis was forced to punt but the roughing penalty kept the series alive, and the Crusaders took advantage by marching 70 yards in just seven plays, capped by Kuhns' 30-yard touchdown strike to Devan Stubblefield.
Matthew Mariota's extra point made it 20-14 with just five seconds remaining.
Saint Louis pushed the lead to 23-14 on Mariota's 30-yard field goal two minutes into the second half, but Kahuku responded with Jacob Samsel's 26-yard field goal with 5:22 left in the third quarter and then took the lead after PJ Liua's 10-yard TD run and Samsel's PAT with 2:36 remaining.
But that would end the scoring for the Red Raiders, who failed to cross midfield thereafter.
The Crusaders took the lead for good on Kuhns' 8-yard touchdown pass to Riccardo Salas III with 7:19 left in the game, then stretched the lead to 38-24 after Adam Noga's 10-yard run to paydirt with 4:45 remaining.
Saint Louis then sealed the victory with Raymond Caayon's 43-yard scoring scamper with 22 seconds left.
Stubblefield finished with six catches for 117 yards.
