NEW ORLEANS - Say what you want about The Tigers not beating anyone. John Calipari's team just keeps winning.

With the shooting of Chris Douglas-Roberts and the inside presence of Joey Dorsey and Robert Dozier, Memphis (31-3) made it 23 straight wins by beating the Mean Green (23-11) in the first round.

Douglas-Roberts had 16 points, Dozier had 11 and seven rebounds, and Dorsey had nine points and 15 rebounds. Andre Allen added 14 points as Memphis overcame a slow start to grab control late in the first half and hardly let up against its Sun Belt opponent.

Memphis will be at it again Sunday, playing a second-round game against Nevada.

Keith Wooden led North Texas with 16 points. Calvin Watson scored 13 and Kendrick Davis scored 12.

The Mean Green put up a good fight early, taking a six-point lead with baskets inside and out. They were up four when Douglas-Roberts, an all- Conference USA pick and Memphis' leading scorer, got his third foul more than nine minutes before halftime.
