(Reuters) - Polish third seed Agnieska Radwanska fought back from 2-5 down in the second set to reach the semi-finals of the BNP Paribas Open with a 6-2 7-6(3) victory over world number nine Petra Kvitova on Wednesday.
Radwanska, who was a runner-up in the event two years ago, raced into a 4-0 lead in the tiebreak before wrapping up victory after a little more than an hour-and-a-half of action at the Indian Wells Tennis Garden in California.
The 27-year-old from Krakow will next face either top seed Serena Williams or defending champion Simona Halep, who were scheduled to play later on Wednesday.
