According to ESPN's Jeff Passan there is a plan being developed between MLB and the MLBPA that could see baseball start playing as early as May. The plan would involve all players, coaches and need staff to be sequestered in Arizona.

Passan laid out the plan in his article:

The plan, sources said, would dictate that all 30 teams play games at stadiums with no fans in the Phoenix area, including the Arizona Diamondbacks' Chase Field, 10 spring training facilities and perhaps other nearby fields. Players, coaching staffs and other essential personnel would be sequestered at local hotels, where they would live in relative isolation and travel only to and from the stadium, sources said. Federal officials at the Centers for Disease Control and Prevention as well as the National Institutes of Health have been supportive of a plan that would adhere to strict isolation, promote social distancing and allow MLB to become the first professional sport to return.

I'm a fan of anything that get's baseball back.
