In their latest bout on Monday night, it was older sister Venus who walked away victorious in the third round of the Indian Wells Masters tournament (also known as the BNP Paribas Opening), defeating Serena 6-3, 6-4.
This is actually Serena's first Tennis appearance since after the birth of her daughter in September and the match against her sister is the 29th one with Venus losing out in four matches in total.
"This is the earliest the sisters will be playing in a tournament since the 1998 Australian Open, when they met in the second round".
Venus had won just 1 of the pair's last 9 matches, making this 3rd round match 2nd in 10th. She served very consistently.
Now Serena will take on No. 21 seed Anastasija Sevastova in her next match and a spot in the quarterfinals is on the line.
But she recovered from those moments to display stretches of power and precision that left you thinking that she might be back to competitive form later this year. It's good that I don't have to say that this is the best tennis I have ever played and I lost.
The two rode a golf cart together from the players' locker room to the bowels of Stadium 1 at the Indian Wells Tennis Garden without saying a word to each other. But it seems the timing and rhythm on her shots, and her court instincts, are still not where they've been for the better part of two decades. Venus and her father Richard were greeted with boos as they made their way to their seats, with some fans believing Richard had been behind Venus's withdrawal.
'I can't really replicate the situation no matter how much I do in practice.
It is rare for the Williams sisters to play this early in a tournament.
Venus broke Serena at love in the sixth game for a 4-2 lead in the first set.
With the first easy service game, Serena levelled 2-2, 20 points apiece.
Wozniacki said the court conditions were hard but she managed to make adjustments. "I want to continue to go forward".
"It definitely feels like a big deal because I have never gone this far in a tournament", Collins said. So the added elements of the new mother's return would just make it even more challening.
What's interesting about the name Serena has chose is that the Olympic gold victor had chosen the same brand name in the past for her own clothing line, the plans for which seem deferred for now.
