KNOXVILLE, Tennessee (Ticker) -- A journey outside Atlantic Coast Conference play proved to be just what Georgia Tech needed.
Marvin Lewis scored 24 points and B.J. Elder added 20 as the 16th-ranked Yellow Jackets cruised to a 77-62 victory over Tennessee.
It was the final non-conference game of the season for Georgia Tech (17-5), which had lost three of its last four contests, all in the ACC.
"Good teams show up in February. We haven't separated ourselves from the pack yet," Georgia Tech coach Paul Hewitt said. "In the ACC, it's a tough league."
C.J. Watson scored 17 points for Tennessee (11-8), which had won the last eight meetings with Georgia Tech, including a one-point decision last season on a half-court shot at the buzzer.
The Yellow Jackets made sure it would not get that close on Saturday behind Lewis, who made 5-of-6 shots from 3-point range.
"Marvin Lewis is a terrific shooter, maybe one of the best in school history," Hewitt said. "We haven't really sprung him for quality looks."
Tennessee has lost seven of its last nine games.
"Give credit for Georgia Tech coming in here and putting it to us," Tennessee coach Buzz Peterson said.
Tennessee shot just 30 percent (18-for-60) and made only 5-of-23 from 3-point range. Scooter McFadgon had one of the longest days, making just 2-of-13 shots and finished with eight points.
"We seemed to lack energy and our shots weren't falling," Peterson added.
Georgia Tech had three 3-pointers during a 13-2 run that extended its lead to 54-38 with 11:41 left. Elder capped the spurt with a 3-pointer and a short jumper.
The Volunteers moved to within 57-51 with 7:25 left on a pair of free throws by McFadgon. The Yellow Jackets answered with baskets by Isma'il Muhammad and Lewis and Tennessee would get no closer than seven the rest of the way.
