(Reuters) - Czech Denisa Allertova stunned world number two Simona Halep 6-4 6-3 in the quarter-finals of the Guangzhou International Women's Open on Thursday.
The win against the Romanian top seed gave the 22-year-old, ranked 74 in the world, only her second victory against a top 10 player after she defeated Carla Suarez Navarro in the first round of the U.S. Open recently.
After going up 5-4 in the first set, Allertova won six of the next seven games for a 5-1 lead in the second and then closed the match out with a backhand winner.
