Quarterback Nate Pylant lofted a sideline pass to John Paul Lynn, who beat a defender for a 65-yard touchdown.
"We've got a couple play-makers that, if they're crowding the line, we can hit them up with some one-on-one," Augusta Prep head coach Harry Bacheller said.
The Cavaliers were one of four teams participating in Thursday night's football jamboree, along with host Augusta Christian, Curtis Baptist and Westminster.
All proceeds from the $3 entry fee went to the American Cancer Society. It's a cause that hits home with Bacheller.
"We wanted to be a part of something special," he said. "I just was alerted last week that my sister has breast cancer. I want to thank Augusta Christian and everybody involved."
Bacheller said he saw plenty of "wide eyes" from a squad with only three members with experience. The pass would be the Cavaliers' only score, as they fell 24-6 to Curtis Baptist.
Cole Swanson, Cameron McConnell and Matthew Sammons scored for Curtis Baptist.
Augusta Christian took on Westminster in quarters 2 and 4. The host Lions won the second quarter, 19-3, and Augusta Prep's sense of unfamiliarity was echoed by Westminster.
Head coach Ryan Bowers' focus for the new program was fundamentals Thursday night.
Westminster held Augusta Christian to a scoreless tie in the fourth quarter.
Lions head coach Keith Walton said his players were excited to be hitting other team's players, instead of hitting each other.
"We get to manage the clock ... you get to see if the kids have been paying attention in practice," Walton said.
Curtis Baptist head coach Nathan Duffie said he was thrilled to have the opportunity to bring together all four of Augusta's private schools for a scrimmage.
"It's a fantastic idea," he said. "I hope we can do it annually."
