PARIS — It was largely expected. There is no confirmed singles appearance. And still Serena Williams returning to tennis remains nothing short of seismic.The comeback by Williams, 44, one of the biggest stars in sports history, will reverberate way beyond tennis, the sport she dominated before “evolving away” in the summer of 2022.There will be basic curiosity about how she will fare as she plays doubles with Canada’s rising teenager Victoria Mboko at Queen’s, the prestigious grass tournament in west London which starts June 8. Women’s tennis — especially singles — has changed hugely since Williams retired, and should she take to the court solo again, where her game fits in the WTA Tour landscape will be intriguing.Fans hoping that she could win a 24th Grand Slam singles title will surely be disappointed, but even being competitive would add a fascinating dynamic to the WTA Tour. Just Williams’ status as a potential opponent for the stars of today, like Aryna Sabalenka, Iga Świątek and Coco Gauff, would make the draws she plays in — if she gets a wild card — even more of an event.The comeback will also come in stages. Queen’s is not the be-all and end-all, with Wimbledon starting June 30 and the U.S. Open to come this August. Williams’ presence at Wimbledon, which she won seven times, or the U.S. Open, which she more or less owned for a couple of decades, will be tantalizing to organizers, who will be able to see how her time at Queen’s is received and how she plays.
