Venus Williams defeated her younger sister Serena Williams in round three of the BNP Paribas Open at Indian Wells, United States of America in the early hours of Tuesday.
Former world number one Serena, who recently had a baby and is just coming back to active tennis, hit four aces but had her serve broken four times in a 6-3 6-4 defeat to Venus in California.
“It wasn’t easy, obviously,” the BBC quoted Serena, who was in her first event since beating Venus in the 2017 Australian Open final.
Venus advanced to the round of 16 where she will face Anastasija Sevastova.
Latvian Sevastova beat German Julia Goerges to advance.
It was the 29th meeting between the Williams sisters – Serena now leads 17-12 – and it lasted 87 minutes in front of a main stadium crowd of more than 10,000 fans, including current world number one Simona Halep.
Serena, 36, has won a mind-boggling 23 Grand Slam singles title, while Venus, 37, has won an impressive 10.
“It was good to play and try to get in the rhythm and get into the swing again,” added Serena, who gave birth just over six months ago.
“I can’t really replicate the situation no matter how much I do in practice. I make those shots 10 times out of 10 in practice.
“It’s just the nerves, the anticipation you feel naturally. It’s a little bit of everything that comes in a match that just doesn’t normally happen.
“It’s good that I don’t have to say that this is the best tennis I have ever played and I lost. My room for improvement is incredible.
“So I have just got to keep saying at each tournament that my goal is just to be better than the last. I don’t want to go backwards.”
