The Ottawa defense held the Spires to negative 1-yard rushing, the second best mark by an Ottawa defense in program history.
Luke Lundy finished with a career-best 172 yards rushing, which ranks 10th all-time in the Ottawa record book for single-game rushing. He averaged 6.8 yards per carry on 25 attempts. Lundy also had two rushing touchdowns.
Ottawa finished with 386 yards rushing, which also is one of the top marks for a single-game.
Ottawa earlier this season set the single-game rushing record with 466 yards against Bethel.
DeVontae Corbitt had three interceptions, which ties him for second for a single-game. He returned two of those picks for touchdowns.
“It was the outcome we wanted,” Ottawa coach Kent Kessinger said. “Our guys played extremely hard. We created turnovers.
“We put pressure on their quarterback. Corbitt had a couple of big ones. We had some really good plays.”
“They taught me to get prepared before,” he said. “They knew what routes were coming. It showed on the field.
“I just got it went to the end zone. That is what you taught. I have been working so hard and I wanted it.”
The defense slowed down good offenses the past two weeks. Saint Mary had 362 yards of offense and six turnovers.
“They have scored a lot of points the last couple of weeks,” Kessinger said. “It was a good showing from our D.”
Ottawa defensive coordinator Josh Homolka said he went back to a few things the Braves have done in the past.
“We did a good of executing,” Homolka said. “We played a different set.
“We can mix it up a little more with personnel. When they come to play us, we will be ready.”
Ottawa chewed up the Spires on the ground. Quarterback Mike Behr had 135 yards rushing.
“It was nice to run the football,” Kessinger said. “Mike did a really good job of distributing the ball.”
Ottawa (5-1, 4-0) plays 1:30 p.m. Saturday at Sterling.
