The George Mason basketball team made first-year Coach Rick Barnes' home debut a bit special last night, defeating the University of North Carolina-Greensboro, 107-79, to become the first team to score more than 100 points at the three-year-old Patriot Center.

Junior guard Earl Moore set a personal career-high for the second consecutive game as he scored 26 points on 11-of-14 shooting from the floor for the Patriots (1-1).

Junior forward Kenny Sanders had 24 points and point guard Amp Davis had 12 points and 10 assists.

The Spartans, a Division III school that will be moving up to Division II next year and to Division I in 1991-92, were coming off a 77-52 victory over Division I East Tennessee State. After 10 minutes last night, however, they lost control by committing five straight turnovers and trailed by about 20 points most of the night in falling to 3-4.

"What helped us a lot was, after getting beaten by Seton Hall {85-63 in the opener}, we had a long time off," said Barnes, an assistant at George Mason from 1981-85. "Everyone was sitting around stewing . . . After that Seton Hall game, I could see these guys wanted to win. We watched films of that game for four hours the day after we got back. Tonight, we could have played another 40 minutes."

North Carolina-Greensboro stayed close early, trailing, 23-22, after Verdel Ellis' reverse layup with 10:11 left in the first half. Mason then rattled the overmatched Spartans with a fullcourt press that produced five turnovers in the next 86 seconds and took a 32-22 lead.
