Fayetteville, AR (SportsNetwork.com) - Michael Qualls scored 21 points and hit four 3-pointers in No. 18 Arkansas' 84-69 win over Missouri.

The Razorbacks (21-5, 9-3 SEC) scored 18 points off 20 Missouri turnovers and were 10-for-22 from long distance. Bobby Portis scored 16 with nine rebounds and Anton Beard added 13 points with five assists.

The Tigers (7-19, 1-12) lost their 12th straight game despite getting 13 points and 10 boards from Johnathan Williams III. Tramaine Isabell equaled Williams for the team lead with 13 points, while Montaque Gill-Caesar and Jakeenan Grant each scored 11 in the loss.

Isabell's 3-pointer near the midpoint of the first half gave Missouri a three-point lead, but the Tigers would not score for the next seven minutes, allowing the Razorbacks to build a 12-point lead.

The run was ended by Gant's jumper with 3:25 to play, and he scored five more points to close the half with the Razorbacks leading 37-29.
