Atlanta ? Georgia Tech coach Paul Hewitt was pleased with three of his freshmen. He was not very happy with leading scorer B.J. Elder.

Isma’il Muhammad scored 16 points, and Luke Schenscher added 14 to power No. 9 Georgia Tech to a 90-48 rout of Charleston Southern on Wednesday night.

Jarrett Jack contributed 13 points, Anthony Morrow added 11, and Will Bynum had 10 as the Yellow Jackets (8-1) had their largest blowout of the season. Georgia Tech beat Georgia 87-49 on Dec. 5 for its previous best.

Elder didn’t play in the second half after scoring five points on 2-of-3 shooting, including a three-pointer, in 14 minutes of the first half.

Elder was not injured, and Hewitt did not directly answer why he didn’t play in the second half.

“He didn’t do anything wrong. I just made a decision,” said Hewitt, who apparently was upset with Elder’s effort.

“He has a lot more to give,” he said. “I’ve run out of time to get it out of him. He’s our best all-around talent. I don’t know what to do. Hug him, yell at him. I just want to see B.J. be the best all the time.”

Elder was unavailable for comment after the game.

Hewitt’s three youngsters — Morrow, Ra’Sean Dickey and Zam Fredrick — all had season-highs in minutes. Morrow played 18 minutes and was 4-of-7 shots from the field, including two three-pointers. Dicky played 17 minutes and had nine points and had six rebounds and Fredrick had six points.
