FAYETTEVILLE, Ark. (AP) -- Arkansas responded to its only loss in the last 25 days by getting back into the win column.

Freshman Marshawn Powell scored 16 of his game-high 26 points in the first half as the Razorbacks defeated South Carolina 92-79 on Wednesday night. Courtney Fortson added 19 points, nine rebounds and eight assists.

Sam Muldrow scored a career-high 23 points and grabbed eight rebounds for South Carolina, which lost for the third time in four games. Devan Downey scored 28 points for the Gamecocks (14-11, 5-6 Southeastern Conference), but the 5-foot-9 senior needed 28 shots to get them.

The Razorbacks (14-12, 7-4) led 40-33 at halftime after shooting 52.8 percent and used a 17-1 run early in the second half to pull away. The Razorbacks have scored more points in a game only once this season -- in a 97-94 home loss to Morgan State on Nov. 24.
