Novak Djokovic has called the US Open's protocols "extreme", Ashleigh Barty remains hesitant, while Rafael Nadal wants tennis' restart to be "responsible", so what chance is there of two Grand Slams going ahead later this year?
Speaking to Prva TV in his home country, he said "we would not have access to Manhattan, we would have to sleep in hotels at the airport, to be tested two or three times per week".
Nadal said he now has no inclination to travel to events, while Djokovic claimed protocols allowing just one person with him on site were "extreme" as his entourage usually includes a coach, hitting partner, physiotherapist and fitness guru.
"I had a telephone conversation with the leaders of world tennis, there were talks about the continuation of the season, mostly about the US Open due in late August, but it is not known whether it will be held", Djokovic, a 17-time Grand Slam champion, said.
'If the US Open didn't go ahead that would be another grand slam they are missing, ' said 30-year-old Evans.
Earlier in the week, Rafael Nadal, who overcame Daniil Medvedev in last year's men's singles final, said, "If you asked me if I want to travel to NY today to play a tennis tournament, I will say no - I will not".
Both the ATP and WTA tours remain on hiatus through July as dozens of tournaments have been scrapped, including Wimbledon.
"If you asked me if I want to travel to NY today to play a tennis tournament, I will say no - I will not", said Nadal.

Top-ranked Novak Djokovic is thinking of skipping the U.S. Open - if it is played - and instead returning to competition on clay ahead of the rescheduled French Open. "But the question is, how many players are willing to accept those terms?"
I don't think having one person of your team only allowed is such a big deal - the majority of the draw would only travel with one coach.
The Serb suggested economic factors were behind the push to play the tournament.
The U.S. Open organisers are evaluating precaution for the competition set up to start onAug 31 without viewers after the COVID-19 pandemic stalled the season in March.
