For once, the 20,000-odd fans on a packed Arthur Ashe Stadium sat quietly engrossed during points.
The sight of the Williams sisters back on court together at the US Open – possibly for the final time – commanded ultimate respect from a chatty crowd known to let their attention wander.
The siblings changed the face of the sport when they emerged as precocious teenagers in the 1990s, going on to dominate the sport with a combined 30 Grand Slam singles titles and 14 doubles victories as a pair.
Three decades later, the sport remains captivated by them.
Serena, a record 23-time Grand Slam women’s singles champion, coming out of retirement this summer sparked excitement among those who saw them in their prime and those too young to have witnessed it.
Seven-time major winner Venus has never “evolved away” from the sport – the words chosen by her younger sister when she last played in 2022 – but instead continued her career with the help of sporadic wildcards.
While that has proved controversial in some quarters, there were few objections about the sisters being invited to play once again at Flushing Meadows.
Their planned return at Wimbledon was scuppered by the knee injury which Serena suffered in her singles match there – ironically a defeat by 20-year-old Joint – before they finally reunited at the WTA event in Cincinnati.
The comeback ended in a match tie-break defeat by Ukraine’s Marta Kostyuk and her American partner Peyton Stearns, with the same fate befalling them in New York.
When the Williams sisters last played on Ashe four years ago, they suffered a straight-set defeat by Czech pair Lucie Hradecka and Linda Noskova in the first round.
It looked like being a similar fate as they meekly surrendered the first set against Chan and Joint, then batted off four break points in the fifth and seventh games of the second set.
But once Serena upped her level to match her impressive sister, they managed to switch the momentum back in their favour and level the match.
An absorbing contest featuring some sensational points saw the Americans fight back again in the decider, only to falter from a commanding lead in the tie-break.
Overall it was a more than credible performance from the veteran pair. Their solid groundstrokes, sharp movement and never-say-die attitude caused problems for their opponents, who deserve huge credit for staying focused in a partisan environment.
“The atmosphere was surreal,” said Joint.
“It was something we’ve never experienced before, and to play against such legends of the game was super special.”
