Zia Cooke had 21 points, Aliyah Boston added 19 points and a career-high 25 rebounds and fourth-ranked South Carolina cleared another significant hurdle in its quest for a Southeastern Conference championship by topping No. 21 Arkansas 91-82 on Thursday night.

Mikiah Herbert Harrison and Tyasha Harris added 13 points for South Carolina.

The Gamecocks (15-1, 3-0 SEC) used a stingy defense to slow down Razorbacks star guard Chelsea Dungee, 1 of the SEC's best scorers.

Dungee racked up 63 points in 2 games last season against South Carolina, but was held in check for most of the game. She began the night 0-11 from the field with 3 airballs. She came in averaging nearly 20 points per game but didn't score her 1st field goal until the third quarter and finished with 14 points.

Just as they did in a 99-72 rout of then-No. 13 Kentucky, the Gamecocks came out strong, bolting to a 31-15 lead after the first quarter.

Alexis Tolefree had 22 points and Amber Ramirez added 20 for Arkansas (13-3, 1-2).

South Carolina heads on the road to Nashville, Tenn. to face Vanderbilt at 5 pm Sunday.
