Tech (8-1-5, 2-0-4 Atlantic Coast Conference) has not been defeated in 13 matches, posting an 8-0-5 mark since Sept. 2, with its last loss occurring on Aug. 31.
The Hokies' five overall draws equals a school record mark set by the 2005 team. Four draws in the ACC this season is the most for Tech since joining the conference in 2004.
"I give credit to our team to be able to dig deep and go to the bench and that really helped us tonight," head coach Oliver Weiss said. "We just had an off night, but in the end if we get a point on the road, it's a good result for us."
Junior goalkeeper Markus Aigner made six saves in net and is 3-0-5 in nine appearances this season.
Duke (7-5-1, 2-3-1 ACC) opened the scoring when Joshua Medcalf converted a shot from 18 yards out for his first goal of the season early in the match at 6:59. Medcalf received a midfield pass from Spencer Wadsworth to give the Blue Devils the early advantage.
"We played as poorly as we could in the first half," Weiss said. "We got punished for it with only one goal. Duke could have scored two or three goals (in the first half) but we reminded our guys what character, commitment, and attitude is required to play in this league and get anything accomplished, especially on the road."
Dillie scored his second goal of the season just 2:23 after entering the match in the second half. The Pittsburgh, Pa., native got his right foot on a cross from Marcus Reed and booted the ball into the left corner for the equalizer at 71:14. Dillie has five career goals in 38 games. Tech moved to 3-1-3 this season when the opponents score first.
"Our character was good in the second half and the commitment was there to work hard and not get beat to the ball like we were in the first half," Weiss said. "That improvement was positive. (Dillie) substituted and scored a goal for us, because our starters weren't quite sharp up front."
The Hokies have only been held scoreless once this season and have scored multiple goals in eight of 12 matches this season.
Tech now 1-0-5 in overtime this season and are 2-0-3 against nationally ranked opponents. The all-time series is now led by Duke, 4-2-3.
The Hokies remain in third place in the ACC with 10 points and play their final non-conference match of the regular season against Radford on Saturday in Tech Soccer Stadium. Kickoff is set for 2 p.m. Jerry Massey will provide the play-by-play on ACC Select.
