Daniil Medvedev and John McEnroe both grumble about the US Open heat.

McEnroe discussed the conditions with ESPN broadcasters James Blake and Chris McKendry from a remote desk on Wednesday. He called Medvedev and Rublev's playing conditions "not humane in a way."

"These guys looked like they were going to fall over today. Larry Brown Sports said that he said it was inhumane. I'm sorry. Next time, USTA, I think we should close the roof."

The USTA changed the regulation on Tuesday for the rest of the event. The organizers partially closed the retractable Arthur Ashe Stadium roof to protect spectators and competitors from the sun.

A medical emergency in the spectators delayed Madison Keys and Marketa Vondrousova's quarterfinal match on Wednesday night for eight minutes.Purdy, the final 2022 NFL Draft pick, saved San Francisco unexpectedly.

"Obviously not how you want to start a match, but I feel like I can only offer towels and water," Keys said. "It just felt right."

The USTA claimed the fan had a medical issue and the incident was not heat-related. The fan was removed for site inspection and discharged. Keys claimed the fan was considerably better after seeing a doctor.

Medvedev triumphed 6-4, 6-3, 6-4, but even he was bothered by the heat. He anticipated one player would "die" from heat.

"The only dangerous thing is: How far could we go?" He said during the game.

I don't know what to do. Since it's been nasty for three or four days, we can't suspend the tournament for four days because it ruins everything: TV, tickets, everything. He claimed it wrecks everything.

"I doubt this can be done."
