Serena eyes Aussie return

The 23-times grand slam winner announced her pregnancy in April and will be on maternity leave for the rest of the year. The 35-year-old is engaged to Reddit co-founder Alexis Ohanian.

"It's the most outrageous plan," Williams told Vogue magazine. "I just want to put that out there. That's, like, three months after I give birth. I'm not walking anything back, but I'm just saying it's pretty intense.

"If I lose and I lose again, it's like, 'she's done'. Especially since I'm not 20 years old. I'll tell you this much: I won't win less. Either I win, or I don't play."
