Late in the first quarter, Sun Devils quarterback Taylor Kelly faked a handoff, scrambled toward the line of scrimmage and fired a pass to Strong in the right corner of the end zone.
The redshirt junior leapt and contorted his body as he grabbed the ball with his left hand before tapping his feet in bounds. The touchdown gave the Sun Devils a 10-3 lead.
Strong entered Saturday leading Arizona State with 57 receptions, 821 receiving yards and eight touchdowns.
Arizona State (7-1, 5-1 Pac 12) and Notre Dame are ranked ninth and 10th, respectively, in the latest College Football Playoff rankings.
