Indian Wells: Serena finds inner tiger to advance

Williams has a chance to become the first three-time winner in women's singles at Indian Wells, a feat she failed to achieve last year when she was forced to withdraw from her semi-final match with a knee injury.

World number one Serena Williams stepped up her bid for her first Indian Wells title in 15 years with a straight set victory over Yulia Putintseva 7-6 (7-2), 6-0 on Sunday. The two-time Indian Wells champion Williams had a difficult time with Putintseva in the opening set but then steamrolled through the second to wrap up the win in one hour, 15 minutes.

"The first set was a little tricky, then I had to find my inner tiger, and roar," Williams said.

Williams moves on to the fourth round of the hard court tournament where she will face Kateryna Bondarenko who defeated Lesia Tsurenko 3-6, 6-4, 7-6 (9-7) earlier on Sunday.

Williams has a chance to become the first three-time winner in women's singles at Indian Wells, a feat she failed to achieve last year when she was forced to withdraw from her semi-final match with a knee injury.

Williams, who won the event in 1999 and 2001, returned to the tournament last year, ending a 14-year boycott which began after she beat Kim Clijsters in the 2001 final. That year spectators at Indian Wells booed Serena during the final and jeered her sister and father Richard Williams in the stands.

As the top seed and a 21 Grand Slam title winner, she's the clear favourite this week. Her quest was boosted Saturday with the elimination of two of the top five seeds in the women's draw, Angelique Kerber and Garbine Muguruza.

Although Williams got off to another slow start Sunday but she closed out in style with an ace on match point. She needed a tiebreaker to win the first set, taking the final three points, including the last two on her serve.

"I was just trying to find my rhythm out there. Trying my best to not get off to a slow start," she said. "I was just trying to fight and do what I could."

Radwanska progresses

World number three Agnieszka Radwanska breezed past Romania's Monica Niculescu 6-2, 6-1 to reach the fourth round. The third seed from Poland needed just 87 minutes to eliminate Niculescu following a tough two-hour, 41-minute second round contest which she won 6-3, 3-6, 7-5 over Slovak Dominika Cibulkova.

"I knew I would have to be patient," Radwanska said of playing Niculescu. "I am just very happy to win that match in those two quick sets."

Radwanska is hoping to get back to the Indian Wells final for the first time since losing the championship match to Flavia Pennetta two years ago.
