Poly failed to capitalize on Mission Viejo's only turnover, a botched snap from center that was picked up by William Alo and returned 38 yards to the Diablo 17 with 14 seconds left in the half. But the Jackrabbits threw an incomplete pass, then missed a 33-yard field goal attempt as time expired.
In addition to forcing two turnovers, Mission Viejo's defense held the Jackrabbits to 86 total yards in the first half, including only 24 yards rushing.
"To hold Poly to 14 points," said Marty Mikkelsen, Mission Viejo's defensive coordinator, "if somebody had told me that before we had started, I would have taken it."
Poly tried its luck with an on-side kick to open the second half, but Mission Viejo recovered it, then marched 49 yards in seven plays, taking a 21-0 lead on an eight-yard touchdown reception by tight end Konrad Reuland. A pass-interference penalty on Alvarez was also a key to the drive.
The Jackrabbits scored on their next possession, moving the ball 60 yards in eight plays and scoring on a 24-yard pass from Scott to Terrence Austin with three minutes left in the third quarter. Scott, who completed 16 of 25 passes for 164 yards, completed all five of his passes on the drive.
The Diablos quickly answered as Sanchez found Sean Fitzgerald in the end zone with a 15-yard pass on fourth and goal, giving Mission Viejo a 28-7 lead early in the fourth quarter.
"Our offense played great in the second half," said Sanchez, who was nine of 19 for 139 yards with no interceptions. "And our defense played great in the second half."
Cruz Parson, who had been rotating at quarterback with Scott, came in for three plays in the second quarter before injuring his right knee. He did not return.
DeSean Jackson had seven catches for 82 yards and one touchdown, an eight-yarder to make it 28-14 with 7:24 left in the game.

Ontario Christian quarterback Lance Cromer completed eight of 19 passes for 218 yards and, in addition to the touchdown pass to Owens, hit Mike Trabbie for an 80-yard score.
Ontario Christian (4-0) lead 27-7 at halftime, before San Dimas closed the gap to 41-35 with 5:22 left in the game, but the Knights scored on three consecutive possessions to close the door.
