COLUMBUS - Isma'il Muhammad has a year left at Georgia Tech, but teammate Jarrett Jack already has a job lined up for him.

''I asked him if he's trying to get on SportsCenter's Top 10 plays,'' Jack said with a laugh. ''He's making regular-occurring appearances. They need to hire him up there.''

B.J. Elder and Marvin Lewis combined for nine points in a 13-0 first-half run and Muhammad's high-wire dunk shifted the momentum in the second half to lead No. 13 Georgia Tech over Ohio State 73-53 Wednesday night in the ACC/Big Ten Challenge.

It was Ohio State's worst loss in its six years in Value City Arena, where the Buckeyes came in with a 69-13 record, including 13-3 against ranked opponents.

Elder finished with 18 points, Lewis had 15 and Jack 14 for the Yellow Jackets (6-0), who matched their best start since 1994-95. Georgia Tech won the Preseason NIT last week, along the way pounding No. 1 Connecticut 77-61 and Texas Tech 85-65.

The Yellow Jackets' win continued the ACC's domination in the challenge. Georgia Tech came in having won just one of four games in the annual head-to-head meetings with the Big Ten, while Ohio State was 1-1.

The Yellow Jackets' defense forced 20 turnovers and held Ohio State to 32.7 percent shooting from the field.

''We feel like we're a team that can really swarm defensively,'' Tech coach Paul Hewitt said. ''We've got a number of guys who can guard multiple positions. We've been causing people to turn the ball over pretty well in these first six games.''

Ricardo Billings and Velimir Radinovic each scored 12 points and J.J. Sullinger added 10 for the Buckeyes (2-3), whose worst previous loss at Value City Arena was 72-58 to Michigan State last March 8.

''The thing that's disturbing to me, and I take full responsibility for this, is we look like a team that has not been coached a day,'' said Ohio State coach Jim O'Brien, who has been reduced to whispering because of vocal-cord damage sustained during neck surgery. ''That's what's most embarrassing to me with where we are right now. This was our first home game and I got the sense we were not excited to be playing. I don't understand that.''

The Yellow Jackets led 10-8 when the Buckeyes didn't score for 9 1/2 minutes, missing all seven of their shots from the field with four turnovers as the lead expanded to 23-8.

Ohio State, down 34-23 at halftime, drew as close as 44-36 when Tony Stockman hit three free throws after he was fouled by Muhammad.

Muhammad, who finished with nine points, took away the momentum the Buckeyes had gained when he dunked while jumping over Billings, and was fouled on the play. Even a partisan crowd of 13,859 oohed and aahed after Muhammad soared in for the three-point play.

''That was when momentum shifted, definitely,'' Muhammad said. ''Coach Hewitt said anytime I can get a big dunk, go for it because it really deflates the other team.''

Muhammad, averaging 15 points off the bench, then hit a rebound follow to make it 49-36.
