DURHAM, N.C. — Thad Lewis threw three touchdown passes to Eron Riley to help Duke beat Navy 41-31 today.

Lewis threw for 317 yards and ran for 41 more, while Riley finished with eight catches for 137 yards for the Blue Devils (2-1). Duke also got a 37-yard fumble return for a touchdown from Vincent Rey and a short scoring run from fullback Tielor Robinson.

Shun White and Tyree Barnes had long touchdowns for the Midshipmen (1-2), who led 24-20 at halftime before the Blue Devils went ahead for good on Riley's 5-yard scoring catch midway through the third quarter.

It was the second straight year in which Lewis and Riley tormented Navy. In last year's 46-43 loss, Lewis found Riley for four touchdowns. Riley finished that game with six catches for 235 yards.

Navy quarterback Kaipo-Noa Kaheaku-Enhada made his first appearance of the season for Navy after missing the first two games with a hamstring strain. The quarterback ran for 28 yards and threw for 45 yards with a touchdown, but left the game late in the first half due to heat exhaustion.

Navy is coached by Ken Niumatalolo, a Radford High and University of Hawai'i alum.
