SERENA WILLIAMS, 35, won her record breaking 23rd Grand Slam victory at the Australian Open in January roughly eight weeks into her first pregnancy.
Williams, the most successful female player of the Open era, is pregnant – just 12 weeks after winning her record 23rd Grand Slam singles title.
The American, 35, is due to give birth in the autumn, says her representative.
The world number two posted a picture on social media app Snapchat, posing in a mirror with the message: ’20 weeks’, before deleting it.
If accurate, that would mean Williams was around eight weeks pregnant while winning in Melbourne.
Williams will miss the rest of the season, having not played since the Australian Open, citing a knee injury.
She will return to world number one next week, would be eligible to retain her ranking under the WTA special ranking rule if she is ready to play her first tournament within 12 months of giving birth.
Former world number one Victoria Azarenka gave birth to her first child in December and is expected to return to competition at the end of July.
Belgium’s Kim Clijsters, meanwhile, won the US Open in 2009 just 18 months after giving birth to her daughter.
Williams, who announced her engagement to the co-founder of community news and chat site Reddit, Alexis Ohanian, in December, is top of the all-time list of major winners since Grand Slams accepted professional players in 1968.
She is second only to Australian Margaret Court on the list of women’s all-time Grand Slam singles titles leaders – Court won 24 titles between 1960 and 1973.
Court, who won the singles Grand Slam in 1970, gave birth to her first child in March 1972, aged 29, and returned to win three of the four Grand Slam events in 1973.
