BLACKSBURG, Va. -- Duke football took another major step Saturday.
The Blue Devils upset No. 16 Virginia Tech 13-10 at Lane Stadium for their first road win over a ranked team since 1971.
Duke, which has never played in bowls in consecutive seasons, became bowl eligible for the second straight year.
In a mistake-filled game, the Blue Devils (6-2, 2-2 ACC) overcame four interceptions by quarterback Anthony Boone. It helped that Duke's defense intercepted Hokies quarterback Logan Thomas four times.
Duke won for the first time in eight games at Virginia Tech's home stadium and broke the Hokies' 20-game home win streak against non-ranked opponents.
Virginia Tech (6-2, 3-1) out-gained Duke 387-198 and had an almost 20-minute advantage in time of possession, but its offense made mistake after mistake in another poor overall performance.
Hokies kicker Cody Journell missed two field goals -- one from 45 yards that clanged off the left upright and a 40-yarder that sailed wide left.
Journell's second miss came on Virginia Tech's penultimate possession. The Hokies' final drive ended when Thomas' pass intended for Trey Edmunds was tipped in the air and intercepted by linebacker Kelby Brown.
The Hokies trailed 13-0 at the half but finally got on the scoreboard late in the third quarter, capping a 99-yard drive with a 5-yard Thomas rushing touchdown.
Virginia Tech was backed up at its own 1-yard line but Thomas zipped a 56-yard bomb down the left sideline to wide receiver Demitri Knowles. Knowles bobbled the pass before gaining control.
Thomas had a 17-yard run and then completed a 12-yard pass to D.J. Coles before breaking through with his touchdown run. It was his 24th career touchdown run to break the Hokies' record for career rushing touchdowns by a quarterback.
The Hokies then got to within 13-10 on Journell's 42-yard field goal with 9:23 left in the game.
Duke took a 13-0 lead with 6:14 remaining in the third quarter on a 9-yard touchdown run by quarterback Anthony Boone. Boone's score capped a six-play drive that covered 63 yards, 25 of which came on a pass interference penalty against Jack Tyler and a holding flag against safety Kyshoen Jarrett.
Duke overcame three first-half interceptions and led 6-0 at the break. Sophomore kicker Ross Martin kicked field goals of 51 and 53 yards to provide the only offense for either team.
Virginia Tech couldn't get its offense untracked in the first half. Thomas threw two costly interceptions and Journell missed a 45-yard field goal attempt with 42 seconds to go until halftime.
After Journell's field goal miss, Duke drove 37 yards in less than 40 seconds and extended its lead on Martin's career-long 53-yard kick right before halftime.
The Hokies' best possession -- a 16-play, 68-yard drive that ate up 8:27 in the second quarter -- ended with no points. A 2-yard touchdown pass from Thomas to D.J. Coles was nullified by an illegal motion penalty. On the next play, Thomas forced a pass into the end zone that was intercepted by Blue Devils senior cornerback Ross Cockrell.
It was one of five interceptions combined by the teams in an ugly first half. Virginia Tech freshman cornerback Kendall Fuller had two first-half interceptions, and a career-high three for the game, and Hokies defensive end Dadi Nicolas came down with his first career pick on a tipped pass in the second quarter.
Duke senior corner Garett Patterson recorded his first career interception in the first quarter. His pick ended a streak of 116 straight passes without an interception for Thomas.
