The Fort Mill Lady Jackets gave the state's top-ranked Class AAA team, Chester, fits for three quarters before the Lady Cyclones squeezed out a 46-40 win.
Chester was led by Raven Feaster's 15 points and Olivia Gains' 10 points.
Fort Mill trailed by two points, 34-32, after three quarters. But the Lady Cyclones' defense took over, holding Fort Mill scoreless in the fourth quarter until only 3:44 remained in the game. Fort Mill started the quarter going 0-8 from the field.
Chester coach Marilyn Milton was surprised her team didn't play better.
"I think we came in too relaxed," she said. "The intensity wasn't built up. I know we didn't play our best."
Fort Mill senior Jenna White led all scorers with 19 points. Sophomore Lauren Wood added 12 for the Lady Jackets.
