Leslie McDonald scored 21 points as one of five North Carolina players in double-figures in an easy 95-49 win over Mississippi State on Monday at the Maui Invitational.

Roquez Johnson led the Bulldogs with 12 points.
The Tar Heels (4-0) scored the game's first nine points and led 29-6 in less than 10 minutes. Mississippi State never came closer than 20 points behind after that. A fade-away 3-pointer from Hairston put UNC up 42 with 5:30 left in the game and the Tar Heels led by at least 40 the rest of the way.
Mississippi State (1-2) made just seven shots in the first half and shot 28.3 percent for the game. The Bulldogs made just two 3-pointers.
With the outcome clear early, the game became little more than a highlight reel for North Carolina fans, with the Tar Heels seemingly able to score at will.
Hairston closed the first half by making a 55-foot bank shot, then put UNC up 42 with 5:30 left with a fade-away 3-pointer.
After scoring its first four points, Mississippi State failed to string together back-to-back field goals until midway through the second half.
North Carolina coach Roy Williams emptied his bench, using 16 players. McAdoo played the most with 23 minutes.
North Carolina's bench outscored Mississippi State by itself with 51 points.
The Tar Heels shot 47.4 percent and 46.9 percent from 3-point range.
North Carolina next faces Butler, which topped Marquette on a buzzer-beater 3-pointer earlier Monday. North Carolina and Butler will play Tuesday in the winner's bracket of the tournament held at the Lahaina Civic Center in Hawaii.
