Ole Miss turned a 13-0 run, including two highlight-type plays by Davis, to build an insurmountable 70-57 lead with 10:22 remaining. Louisiana never got closer than 11 points in the final two minutes.
Marcanvis Hymon had a double-double with 12 points and 13 rebounds in a balanced scoring attack for the Rebels. Deandre Burnett scored 17 points, Devontae Shuler had 14 and Breein Tyree added 10.
“I thought we settled in during the second half after forcing some things and being tight in the first half,” Mississippi coach Andy Kennedy said. “Louisiana had a lot to do with that. For us, Hymon especially, had a really good game against a really good team.”
Louisiana put four players in double figures, led by Johnathan Stove with 16 points. Cedric Russell scored 15 points, while Justin Miller and Marcus Stroman had 12 points each. The Rajin’ Cajuns led by 10 points in the first half and 42-40 at halftime.
“We’re disappointed, because we came here to win; not challenge, but win,” Louisiana coach Bob Marlin said. “We were there for a half, but we couldn’t match their energy and got beat by 20 in the second half.”
Ole Miss shot 33 of 65 (51 percent), including 7 of 21 from 3-point range. The Rebels finished 21 of 31 from the free-throw line, 13 of 15 in the second half.
Louisiana shot 26 of 71 (36 percent) from the field. The Rajin’ Cajuns had 10 second-half turnovers.
