Freshman center Aliyah Boston was a game-time decision with a minor injury.
Arkansas wishes the decision had gone the other way.
Boston had 18 points, 15 rebounds and seven blocked shots as the No. 1 Gamecocks beat Arkansas, 86-65, Thursday night in Fayetteville for their 16th straight win.
"We've got to play her," head coach Dawn Staley told SEC Network after the game. "She's just smart. She understands the game plan. She rarely makes mistakes."
The Gamecocks, 22-1, improved to 10-0 in the SEC with a big non-conference matchup against UConn set for Monday night at Colonial Life Arena.
Kiki Herbert Harrigan was also dominant for South Carolina with 25 points and nine rebounds. Zia Cooke added 14 points for the Gamecocks, which shot 46 percent from the field to 36 percent for Arkansas.
South Carolina out-rebounded Arkansas 57-31.
"I liked the toughness of our team," Staley said. "We had to dig deep to get this win."
