The first Thursday's singles match of the WTA Finals was played between Agnieszka Radwanska and Simona Halep, with the Pole marching away as the victor, sending home the top-seeded Romanian.
The first set was a close affair, as Radwanska was coming back twice, from 3-1 down and then in the tiebreak from 5-1 down. Opening the match with 30-0, Radwanska dropped serve in that first game, as Halep won four straight points, and the Romanian kept that lead until the fourth game. Radwanska then leveled to 3-3 and the players held their serves all the way to the tiebreak, which Radwanska edged despite trailing considerably after the first six points played.
