When it comes to completing the revised ATP calendar, Pablo Carreño Busta hopes for the best, but prepares for the worst.

The 25th-ranked Spaniard said nations' varied responses to the Coronavirus crisis combined with potential future flare-ups of COVID-19 could create a roadblock to resuming the ATP calendar as scheduled.

Today, the Citi Open in Washington DC cancelled.

"The ATP circuit is complicated because there are players from different countries and each one is in a different situation with the COVID-19," Carreño Busta said in comments published by Spanish publication Marca. "In principle, the clay season will begin in September ending with Roland Garros.

"It [looks] better than in the United States, but the COVID-19 is not easily controlled and at any time there may be sprouts and we have to stop. I hope not. Hopefully it can be played, but there are no absolute certainties."



Carreño Busta, a 2017 US Open semifinalist, said he expects most European players to make a final decision on playing the US Open by the end of this month.
