Michael Qualls added 11 points for the Razorbacks (17-5, 6-3 SEC), who held the Gamecocks to 27.9 percent (17 of 61) shooting and scored 21 points off 20 turnovers. Portis' rebound total matched his career best.
Sindarius Thornwell led South Carolina (11-10, 2-7) with 16 points, while Marcus Stroman added 10. The Gamecocks have lost five of their last six games and seven of nine.
