Neither team orchestrated many crisp possessions throughout a first half riddled with errant passes, wild shots and loose balls.

The Gamecocks committed 10 turnovers against just seven assists in the first half and shot just 32.0 percent from the field, while the Hoyas made just 1 of 8 of their 3-point attempts.

Georgetown capitalized on those 10 miscues and held a 16-0 advantage in points off turnovers as South Carolina trailed at the half for the fourth straight game.
