SOUTH BEND — Ian Book ran 7 yards for a touchdown with 29 seconds left in the fourth quarter to cap an 18-play, 87-yard drive and No. 16 Notre Dame pulled out a 21-20 victory against Virginia Tech on Saturday.

The Fighting Irish (6-2) had committed three turnovers deep in Virginia Tech territory, including a fumble at the goal line that Divine Deablo returned for a 98-yard touchdown to tie the game at 14 with 9 seconds left in the first half. The Hokies (5-3) added a couple of field goals in the second half and the Irish missed one, leaving Notre Dame trailing by six with 3:19 remaining and the ball at its 13.

Book led a methodical drive, converting two fourth downs, including a fourth-and-10 from the Tech 33 for 26 yards to Chase Claypool that gave the Irish first-and-goal from the 7. After two incomplete passes, Notre Dame caught Virginia Tech in a blitz. Book ran away from it and darted into the end zone. Jonathan Doerer booted through the PAT for the lead, Kyle Hamilton picked off a long pass by Quincy Patterson around midfield to end the Hokies’ final possession and the Irish averted a two-game losing streak.

Book passed for 341 yards and two TDs.
