Serena Williams has withdrawn from this week’s BNP Paribas Open and the upcoming Miami Open, so her absence will hand Angelique Kerber a comeback to the top of the WTA rankings on March 20.
Citing a left knee injury, Williams pulled out of Indian Wells without playing a single match and she won’t be ready to play Miami either.
I have not been able to train due to my knees. I am disappointed I cannot be there. I will keep moving forward, continue to be positive. I look forward to being back.
