U.S. Open opponents Taylor Townsend and Jelena Ostapenko got into a face-to-face argument on the Court 11 sideline right after their second-round match ended.

“If it was my knee, that would be more really devastating for me. I feel like my body is actually doing really, really well,” said Williams, who turned 39 on Saturday. Williams took a long pause, clutched at that leg and then took a medical timeout so a trainer could wrap it. I was able to get it somewhat better, but just looking long-term in this tournament, will I be able to get through enough matches? And so, for me, I don’t think I could,” Williams said Wednesday.

But tennis players cannot home-work. And so, as now-rare world travelers, they've also become unwitting first-hand witnesses of how the pandemic is battering the airline industry. But the novelty wore off after near-constant flying became part of her tennis job, until “I really didn't like it, especially long-haul." “The best thing during the lockdown was that I didn’t have to go on the plane.”___More AP tennis: https://apnews.com/apf-Tennis and https://twitter.com/AP_Sports
