SIOUX FALLS, S.D. - Syracuse coach Quentin Hillsman delivered a direct message to Brianna Butler at halftime. "You've got to hit some shots," he told his star guard, "or we're going home." Butler hit some shots, all right, and Syracuse is staying another couple days in South Dakota after upsetting No. 1 seed South Carolina 80-72 in the Sioux Falls Regional semifinal of the women's NCAA Tournament on Friday night.

SIOUX FALLS, S.D. - Syracuse coach Quentin Hillsman delivered a direct message to Brianna Butler at halftime.

"You've got to hit some shots," he told his star guard, "or we're going home."

Butler hit some shots, all right, and Syracuse is staying another couple days in South Dakota after upsetting No. 1 seed South Carolina 80-72 in the Sioux Falls Regional semifinal of the women's NCAA Tournament on Friday night.

Butler scored 10 of her 18 points in the fourth quarter, including the go-ahead 3-pointer with 3:01 left, to send the fourth-seeded Orange to a regional final for the first time.

They'll play Tennessee on Sunday.

Syracuse trailed by as many as 13 late in the first half and was still down 11 in the middle of the third quarter before coming back to stun a Gamecocks team that looked destined to make another appearance in the Final Four. South Carolina got into early foul trouble and never could finish off the Orange.

Alexis Peterson scored 25 points to lead the Orange (28-7), who won for the 14th time in 15 games. Brittney Sykes added 17 and Briana Day had 13 rebounds.

Alaina Coates had 18 points and 16 rebounds for South Carolina (33-2), whose only other loss was to UConn. A'ja Wilson had 15 points and 10 rebounds, and Tina Roy added 17 points off the bench for the Gamecocks.

"I have to give the credit to my teammates and coaches," Butler said.

"They gave me the confidence to come out in the second half and fire. Lex told me they're going to fall. Even Coach gave me the confidence. Even if I was missing, he wanted me to keep shooting."

The Orange's zone defense sagged on star post players Wilson and Coates, giving Roy, Mitchell and Bianca Cuevas open looks from the perimeter. The Gamecocks attempted a season-high 32 3-pointers, but made only eight.
