What will happen from June onwards and what will be the scenarios, from Roger Federer's come back to the French Open in early Autumn. The spread of the Covid-19 pandemic upset the whole season, cancelling and postponing many important tournaments, including Indian Wells, Miami, Monte-Carlo, Madrid, Rome and he Roland Garros.
The season should resume in June with the grass-swing, but there are still many unknowns, related to the duration of the pandemic and its relative peak. The worst-case scenario. The pandemic, initially in France, Germany, Spain, UK and USA and close to the peak in Italy, will last until the summer.
In this case, the on grass-courts tournaments will undoubtedly be cancelled or moved to another date. The same fate, probably for the Tokyo Olympic Games. With Roland Garros rescheduled from 20 September to 4 October, it would be difficult to fit Wimbledon too.
Such a situation would put the whole year at risk, with the not-so-remote possibility of the whole tennis season getting cancelled. The intermediate scenario. The slowdown of the pandemic by the end of June. In this case, Wimbledon would risk cancelling or moving to another date, but the rest of the season should be saved.
Tennis players could come back on the court at the end of July, just for the Tokyo 2020 Olympics. In this case, there could also be the possibility of inserting Wimbledon in early August, even if afterwards there would be only two weeks after the US Open, at in turn two weeks after the French Open.
The best scenario. The pandemic will be under control before June 7th. In this case, the grass-swing and Wimbledon will be saved, as well as the Tokyo Olympics and the rest of the season. For the first time in history, the French Open will become the last Slam of the year, but there will also be the possibility of inserting some cancelled tournaments, like Indian Wells and Miami, perhaps extending the season and postponing the ATP Finals and the Davis Cup Finals in early December.
