World No. 1 Serena Williams is pregnant and is expecting to give birth this fall, her spokesperson has confirmed.
"I have not been able to train", she said in a statement before Indian Wells.
But after giving birth, the former world number one's mind was made up and she began jogging around a park near her house with a pram to get fit. "From a size change difference, it might take longer for that to be an issue with her, depending on how she carries", said Pivarnik, who has studied the impact of pregnancy on exercise for the past three decades.
She has bestrode tennis like a colossus, and now it looks like she may have won the Australian Open in January while in the early stages of pregnancy. She will miss all the matches in the 2017 season but will probably return to the court next year.
