Chantilly’s defense generated five turnovers, sparking a road upset over previously unbeaten No. 15 Oakton in a Virginia AAA Concorde District game.

Sean Huelskamp took one of the Chantilly’s two interceptions back 86 yards for a touchdown and also caught a scoring pass from Sonny Romine, as the Chargers (5-2, 1-1) snapped a streak of five straight losses to the Cougars (6-1, 1-1).

“Those turnovers got the momentum going in our favor,” Chantilly Coach Mike Lalli said. “Offensively we executed well and were doing things the right way.”

The Chargers jumped out to a 21-7 halftime lead, then responded with three straight scores after the Cougars pulled within 21-14. The first came on a 29-yard run by David Kerns, who went backward and reversed field before slipping the defense.

“It was one where as a coach you’re going. ‘No, no, no; yes, yes, yes — but don’t ever do it again,” Lalli said.

Huelskamp’s interception followed, and Oakton never recovered, despite 175 yards and two touchdowns from Mike Wandey.
