Halep beats Wang to reach Indian Wells quarter-finals

The turning point after a string of unforced errors left Halep trailing 5-4 in the first set, prompting coach Darren Cahill to tell the defensive specialist to work longer points and reduce the error count.

Halep went on to lose only one more game, easily seeing off the challenge of the world No.55 from China.

The 26-year-old Romanian showed no sign of the foot injury that forced her to withdraw from the Qatar Total Open in Doha last month and appears poised to regain the Indian Wells title she won in 2015.

First she will have to get past unseeded Croatian Martic, who advanced to the last eight with a straight sets win against Marketa Vondrousova on Tuesday.

“She is a very tough opponent because she is serving pretty strong and also the forehand has a lot of top spin ... So I will have to work hard,” Halep told the Tennis Channel.
