Major League Baseball might be facing the prospect of either beginning its season in Arizona or canceling it entirely due to the coronavirus pandemic, according to ESPN’s Jeff Passan.

Appearing on “Get Up” on Monday morning, Passan told host Mike Greenberg that the plan to have all teams report to Arizona to play in relative isolation is the most likely way baseball can begin in the coming months.

“When it’s all said and done, it seems like it’s going to be Arizona or bust for Major League Baseball,” Passan said. “It may have to get to the point where they say to themselves, this is what we are going to try to do even if we can’t ultimately pull it off.”

Last week, Passan was first to report the details of MLB’s “Arizona plan,” which would call for all 30 teams to play the entire schedule at 10 spring training facilities and the Diamondbacks’ Chase Field while remaining in functional isolation. Players would only be allowed to travel between the team hotel and the ballpark and would not be able to interact with people outside the isolation bubble.

The “Arizona plan” also could include some creative rule changes, such as the use of an electronic strike zone or seven-inning doubleheaders to accelerate the season. For the plan to be instituted, MLB would need its players to sign off, which might be difficult considering the proposal may call for them to be separated from their families for months.

According to Passan, playing in Arizona is much more likely than a similar plan to begin the season split between spring training sites in Florida and Arizona. He also ruled out the theory that the MLB season could begin in Japan before moving back to the United States.

As of now, the league and its players are in a holding pattern, with the course of the coronavirus pandemic in the coming weeks likely determining much of the immediate plan moving forward. If baseball does end up starting its season in Arizona, the hope is that the league could get to a point where they’d start gradually returning to normalcy.

“The hope is that this starts off as a biosphere and eventually we get to the point in this country, through testing and through antibody testing and understanding a little better what the coronavirus exactly is, that they can move beyond this biosphere and go back to their cities,” Passan said. “And even though they’ll probably be playing in empty stadiums for the rest of the year, the idea is that this would be a two or three month thing as opposed to a four, five or six month thing that encapsulates the entire season.”
