Tennis may not return until 2021 because of the coronavirus pandemic, All England Lawn Tennis Club (AELTC)\nchief executive Richard Lewis said on Thursday. This summer's Wimbledon Championships were cancelled on Wednesday for the first\ntime since the second World War. Lewis, who is to step down in July, said he hoped the situation will\nstabilise in the coming months to allow the hardcourt season to get underway\nbefore the U.S. Open begins on 24 August. "The optimist in me - and I'm often not optimistic - still hopes that\nthe American hardcourt season will take place," Lewis said. "One hopes that things have settled down a bit and those big 1,000-point\ntournaments -- Montreal, Toronto, Cincinnati -- can happen in the lead-up to\nthe U.S. Open. We all know that's probably tenuous at the moment. "I don't think it's unrealistic to say that there may be no more tennis\nthis year. But let's hope that the U.S. Open and Roland Garros can take\nplace."
