CHAPEL HILL, N.C. ? Sean May scored 11 of his career-high 26 points in the first 51/2 minutes of the second half, and No. 10 North Carolina shot 61 percent in a 115-81 victory Sunday over George Mason.

The Tar Heels (5-0) remained one of five undefeated teams in the Atlantic Coast Conference, notching their first 100-point game under new coach Roy Williams. It was the most points for North Carolina since it scored 129 against VMI in 1994.

May, 10-for-12 from the field, had 23 points and 14 rebounds against Illinois Tuesday. Raymond Felton had a school-record 18 assists — 13 in the second half — while ACC scoring leader Jawad Williams and Rashad McCants had 21 points each.

Jeff Lebo had 17 assists in a game for North Carolina in 1988, and Ed Cota matched that mark in 11 years later.

Mark Davis led the Patriots (4-2) with 21 points.

No. 17 Gonzaga 96, George Washington 91

Washington — Ronny Turiaf matched his career-high with 29 points, and Gonzaga’s inside game was too much for George Washington in the championship game of the BB&T Classic.

Backup guard Erroll Knight added 18 points for the Bulldogs (6-1).
