ATLANTA (Ticker) -- Jarrett Jack's hot shooting quickly turned a tight contest into a laugher.
Jack made a career-high five 3-pointers and scored 22 points as No. 10 Georgia Tech pulled away for a 92-69 victory over Virginia in an Atlantic Coast Conference matchup.
With the Yellow Jackets (11-2, 2-0 ACC) trailing 32-30 after a 3-pointer by the Cavaliers' Adrian Joseph, Jack sparked a 7-0 run with a three-point play. He added one of his three first-half 3-pointers for a 40-35 lead with 2:21 remaining.
Georgia Tech, playing without second-leading scorer B.J. Elder for a second straight game, led 44-38 at the break behind 46 percent (17-of-37) shooting and 18 points from its reserves.
"At halftime, there were no complicated speeches," Georgia Tech coach Paul Hewitt said. "I just said, 'Guys, you've got a chance to be 2-0 in the ACC. If Virginia comes out in the second half and plays better basketball than us, we'll shake their hands and go home.'
"All we asked them to do was contest every shot, run down every loose ball and run the floor as hard as you can in transition. That's what we're about. This team is built on defense, effort, running the floor hard."
In the second half, Jack hit a pair of 3-pointers as the Yellow Jackets stormed out of the intermission with a 10-2 run, grabbing a 54-40 advantage with 15:03 remaining. Isma'il Muhammad added a pair of layups and Anthony Morrow made four straight free throws to push the lead to 72-47 with 9:07 remaining.
"I thought we played a pretty good first half, down only six, but I thought we missed too many free throws," said Virginia coach Pete Gillen, who fell to 3-11 against Georgia Tech. "We were 12-of-20 in the first half and you've got to make free throws on the road. I thought we missed free throws and couldn't score in the second half and got frustrated and then didn't get back on fast-break defense and they hurt us on the offensive boards."
Morrow, Anthony McHenry and Ra'Sean Dickey scored 13 points apiece and Luke Schenscher added seven along with 13 rebounds and five blocks for Georgia Tech, which improved to 11-0 when holding an opponent under 70 points.
"The guys that really beat us, besides Jack, were the two freshman, Dickey and Morrow," Gillen said. "Dickey had 11 points in the first half which was the difference - we could have been tied or up a couple if it wasn't for him and Morrow. We decided to cheat on Morrow but we let Dickey get the ball too deep. Those two were the difference."
R.J. Reynolds scored 21 points and Elton Brown chipped in 10 and nine rebounds for Virginia (9-3, 0-2), which shot 28 percent (11-of-39) in the second half in its second straight road loss.
The Cavaliers, who played without leading scorer Devin Smith for the third straight game because of an ankle injury, hung tough in the first half despite a slow start by Brown, who entered the contest averaging 15.3 points. He had just four points at the half on 2-of-8 shooting.
"Elton Brown really concerned me, so we put a lot of emphasis on him and doubled him in the post (in the first half)," Hewitt said. "In the second half, we decided not to double him. We just told Luke and Ra'Sean to just guard him and we would try to give help where we can."
Gary Forbes scored 11 points and freshman sensation Sean Singletary had his third sub-par game, scoring just six points on 1-of-7 shooting. After beginning the season with 10.3 points in his first nine games, the 19-year-old has averaged just 6.3 points on 17 percent (4-of-24) shooting in his last three.
