DURHAM, N.C. (AP) -- Before Ty Jerome hit the shot that effectively beat No. 4 Duke, the Virginia guard stole the ball.
It figures. For the second-ranked Cavaliers, even their daggers trace back to that punishing defense.
Virginia beat the Blue Devils 65-63 on Saturday after Jerome hit a critical 3-pointer with 37.6 seconds to play.
Kyle Guy scored 17 points and hit two free throws with 6.1 seconds left, Jerome finished with 13 points and Devon Hall had 14 points to help the Cavaliers (20-1, 9-0 Atlantic Coast Conference) win their 12th straight and their first at Cameron Indoor Stadium since 1995.
"They find ways," coach Tony Bennett said. "They're a team that's a joy to coach because they're pretty clear who they are, and it doesn't matter who's hitting the shots."
The nation's stingiest defense held the top offense in Division I to more than 28 points below its average of 91.7 points. Virginia, which entered allowing an average of 51.6 points, held the freshmen-dominated Blue Devils 15 points below their previous season-low point total.
"I was a freshman once, and you're not really prepared for this type of pressure that we put on the ball and our defense," Guy said.
Marvin Bagley III had 30 points and 14 rebounds, while Wendell Carter Jr. had 14 points and 15 rebounds for the Blue Devils (18-3, 6-3).
Jerome started the key sequence by stealing freshman Trevon Duval's long pass in the Duke frontcourt, then ended it with a 3 with the shot clock winding down that put Virginia up 63-58. Both he and Guy made things tense by missing the front ends of one-and-ones in the final minute.
Bagley swished a deep 3 with 7.4 seconds remaining before Duke fouled Guy again, and this time he hit both attempts to make it 65-61 and effectively seal it. Bagley added a layup at the buzzer.
