ATLANTA (AP) Devin Oliver and Jordan Sibert each scored 20 points, Vee Sanford added 15 and Dayton beat Georgia Tech 82-72 on Wednesday night.
Dayton (4-0) maximized its chances on Georgia Tech's 19 miscues to outscore the Yellow Jackets 33-6 on turnovers.
Daniel Miller finished with 20 points and Marcus Georges-Hunt had 16 for Georgia Tech (3-1).
Sibert, a junior transfer from Ohio State, began his career at Dayton with a buzzer-beating 3 that gave the Flyers a victory over Indiana-Purdue Fort Wayne in the opener.
Sibert's 3 to score his 15th point put Dayton ahead 34-30 with 3:17 left in the first.
Facing former coach Brian Gregory - now in his third season at Georgia Tech - for the first time, the Flyers got off to a difficult start. They missed seven of their first eight 3-point attempts and trailed by nine points midway through the first half.
But Dayton went on a 13-0 run that ended on Sanford's 3 from the left corner, and the Flyers led 37-30 with 2:39 to go before intermission.
Georgia Tech never seemed to recover.
After Miller's layup cut the lead to six with 7:28 left in the game, the Flyers needed just over 1 minute to take the game's biggest lead at 14.
Sanford and Sibert each hit 3-pointers before Oliver stole the ball on Dayton's end and scored a reverse a layup that made it 68-54.
Georgia Tech point guard Trae Golden, a senior transfer from Tennessee who's in his first season with the Jackets, had all six of his turnovers in the first half. He finished with 13 points, but had just three assists in 31 minutes.
Over the last seven seasons, the Flyers have won 20 of their last 39 games against major conferences. Beating Georgia Tech gave Dayton, which plays in the Atlantic 10, five straight wins over Atlantic Coast Conference opponents.
