Ocean View, which amassed 543 yards of offense, including 413 on the ground with only two ballcarriers, had first-and-goal on the Mesa three-yard line on its final possession.
But the Mustangs' defense, which was largely abused all night by Ocean View quarterback Timmy Robinson (130 passing yards and 112 rushing yards) and tailback Travis Sparks-Jackson (301 rushing yards and 75 more on his lone reception), came up big on the next three snaps to force the ill-fated field-goal try.
On first down, Mesa defenders Kevin Salyer, Ulices Martinez and Noah JayaRajah combined to stuff Sparks-Jackson for a one-yard loss off right tackle.
After a would-be Sparks-Jackson touchdown run was erased by a holding call that moved the ball to the 12, the 6-foot- 1, 225-pound Robinson barreled to the six-yard line on a scramble.
Robinson's third-down option pitch was errant and Mesa's Jake Comer corralled the Seahawk who picked up the fumble for an eight-yard loss. The subsequent field-goal try, a low liner by Sparks-Jackson, hit the front of the crossbar and caromed harmlessly back into the end zone.
The Mustangs, who had success running and passing, earned a first down on the ensuing possession, enabling them to run out the clock.
Three Mesa scoring drives were set up by either a turnover or a long kickoff return by senior Mario Smith.
Middle linebacker Oronde Crenshaw's interception set up a four-play drive that opened the scoring for Mesa, which led the entire first half, but trained twice after intermission.
Smith, who rushed for 186 yards and a pair of touchdowns, bolted 75 yards with the kickoff that followed Ocean View's first score. The return to the Seahawks' 18, allowed Mesa to score three plays later, when quarterback Nathan Alvis hit Crenshaw for a 14-yard touchdown pass.
