Williams too strong for Azarenka
Serena Williams will face Agnieszka Radwanska in the Wimbledon final after seeing off Victoria Azarenka 6-3 7-6 in the last four.
Williams won the final three games of the first set to seal a 6-3 victory but second-seed Azarenka managed to take the second set to a tie break, losing 8-6 to the American.
The 30-year-old, who has won four of her 13 Grand Slam titles to date at SW19, was delighted to reach the final and admits she is desperate to secure a fifth Wimbledon crown.
She told the BBC: "I've been working so hard, I really wanted it. She was playing well and I got a little tight in the second set. I was looking too far in the future. I was so close, but I can't do that. I was happy to get through that second set tie-break."
Williams will face third-seed Radwanska in Saturday's final after the Polish star secured a straight sets victory over Angelique Kerber in the first semi-final, and the sixth-seed admits she will have to be at her best again if she is to take the top prize.
On Radwanska, she added: "She's doing unbelievable. She's playing so great. Wow, she's going to get every ball back."
