Sonny Weems scored 22 points, including a driving basket with 20 seconds remaining that helped Arkansas edge Mississippi 75-69 Saturday.
The Razorbacks blew an early 14-point lead, extended their advantage to double digits again in the second half, then had to hold on amid a barrage of three-pointers by the Rebels' Chris Warren.
Warren scored 11 straight points for Ole Miss late in the second half and his three-pointer cut Arkansas' lead to three with under a minute remaining.
Weems then drove through the middle of the defense and scored on a tough shot near the basket to make it 72-67.
Zach Graham missed at the other end, ending Ole Miss' chance at a comeback.
Patrick Beverley added 17 points and 13 rebounds for Arkansas (17-5, 6-2 SEC).
Warren alone was 6-of-8 from 3-point range for Ole Miss (16-5, 3-5) and he finished with 26 points.
