DURHAM, N.C. -- Chase Rettig threw two third-quarter touchdown passes and Boston College made a late defensive stand to defeat Duke 21-16 on Saturday.
Rettig completed 12 of 24 passes for 230 yards for the Eagles (5-5, 3-4 Atlantic Coast Conference), who won their third consecutive game.
Duke (3-7, 1-5) drove to the Boston College 4-yard line on its final drive, coming up short in its bid for a second last-minute comeback win in as many weeks. Sean Renfree's fourth-down pass was batted down by defensive end Max Holloway with 46 seconds left.
Montel Harris rushed for 109 yards and a touchdown for Boston College, but he also lost two fumbles in the red zone.
Duke's August Campbell returned Harris' second fumble 95 yards for a touchdown to trim Boston College's lead to 21-16 early in the fourth quarter.
Leading 21-9, Boston College was on the verge of taking a commanding lead when Duke's defense responded. Harris fumbled on third-and-4 from the Duke 9 after a hit by Walt Canty, and Campbell scooped up the loose ball.
He raced toward the left sideline, skipping out of a diving tackle attempt by Rettig before outrunning offensive tackle Emmett Cleary to the end zone for the longest fumble return in school history.
Rettig passed for 95 yards in the third quarter, tossing a 38-yard touchdown pass to Bobby Swigert on Boston College's first possession of the half. After a fumble by Duke's Conner Vernon, Rettig connected with Ifeanyi Momah for a 4-yard touchdown on a fade route.
The Eagles led 7-6 at halftime, scoring just once on three trips inside the Duke 25. Harris lost a fumble on the first of those opportunities, but he responded with a 15-yard touchdown run up the middle midway through the second quarter.
The Blue Devils, who netted minus-8 rushing yards on 17 attempts in the first half, got field goals of 29 yards and 40 yards from Will Snyderwine before halftime.
