Boston's Chris Sale, out for the season following Tommy John surgery, thought about the prospect of his teammates sequestered in the Phoenix area for an extended period if Major League Baseball and its players adopt an all-Arizona start to the season.

"I don't know if I could look at my kids just through a screen for four or five months. Same thing goes with my wife," the pitcher said Tuesday. "That's a long time. But people have done it in harsh scenarios, I guess. I think there's a lot of figuring out to do."

A plan dictating that all 30 teams play games with no fans at stadiums in the Phoenix area, including the Arizona Diamondbacks' Chase Field, 10 spring training facilities and perhaps other nearby fields, has emerged above other options as the likeliest to work and has been embraced by MLB and MLB Players Association leadership, who are buoyed by the possibility of baseball's return and the backing of federal officials, sources told ESPN's Jeff Passan on Monday.

With the MLB season delayed due to the coronavirus, both sides are searching for ways to get under way. Kansas City manager Mike Matheny said he would feel privileged to help the country return to a semblance of normalcy and provide an escape for fans.

"Just jump in and trust that we may not know when we'll reconnect with our families and trust that when health officials decide it's OK, we'll be able to do that," Matheny said. "But in the meantime, do something that would really help the healing process."

Baseball officials intend to study which options could be viable economically and would gain necessary approvals. The league said it has not yet sought approval of any plan from federal, state and local officials or from the players' association.

"MLB has been actively considering numerous contingency plans that would allow play to commence once the public health situation has improved to the point that it is safe to do so," the commissioner's office said in a statement. "While we have discussed the idea of staging games at one location as one potential option, we have not settled on that option or developed a detailed plan."

Arizona has 10 spring training ballparks plus the Arizona Diamondbacks' Chase Field all within about 50 miles. Phoenix Municipal Stadium -- Oakland's old spring training base and now Arizona State's stadium -- is an option, along with Grand Canyon University's Brazell Field.

Chase Field could host several games each day, following its switch to an artificial surface ahead of the 2019 season.

"We would not have been able to do it with grass, but now with the synthetic grass, absolutely," Diamondbacks president Derrick Hall said.

Baseball's look would be different in empty ballparks. Players from the Orioles and the Chicago White Sox recall playing in a deserted Camden Yards in 2015, when civil unrest caused a closed-doors game. The game sped along in 2 hours, 3 minutes.

"It was a weird feeling having nobody in the stands," said Sale, a member of those White Sox. "But sometimes you got to adapt. Sometimes you got to do some things for the greater good of what's going on around you."

That was a one-off. This would be every day, for about 15 games a day.

"My sense is that it divorces the game from the fans except via television, and that's a mistake," former MLB commissioner Fay Vincent said. "I don't think a televised game without an audience and without fan reaction is a great idea. I think it's born in desperation. I'm a traditionalist and a bit of a romantic. I think we ought to wait until we can present the game in its best light."

Phoenix Mayor Kate Gallego maintained that player and public health would be the top priorities.

"There is not a person on the planet who doesn't want to get back to a time and place marked by familiarity, and there is nothing more familiar than sports, especially the great American pastime of baseball," she said in a statement. "All of our lives post-COVID-19 will look different. At the city we value flexibility and innovation and are willing to work with the many different sports franchises that call Phoenix home, but only if public health leads every single discussion."

Former manager Jim Leyland thinks the game will return to the field at some point this year.

"I do applaud people that are trying to be creative and come up with different ideas," he said. "At the end of the day, they'll come up with some type of a wonderful package. It's just a matter of when that's going to be allowed."

Starting the season in Arizona presents plenty of complications:

SOME LIKE IT HOT

Temperatures average a high of 105 in Phoenix in June, and the thermometer just starts to dip at 5 p.m., when presumably many games would start to be in prime time on the East Coast. Chase Field's retractable roof and air conditioning could make it a site for doubleheaders or even tripleheaders.

EXPANDED ROSTERS

Given the heat and the compacted schedule, active rosters could be expanded from 26. With teams isolated and the status of minor leagues uncertain, extra players could be kept in the group.

MONEY MATTERS

How much would it cost to put teams and the personnel that travel with them in hotels for double the usual time (no true home games, except for the D-Backs)? There presumably would be savings with not needing charter flights for road trips, but what percentage of that cost was committed in advance? In addition, the absence of ticket revenue would be damaging for many teams. Would player salaries be cut? Who gets to sell stadium signage?

HOME-FIELD ADVANTAGE

Would the 15 spring training tenant teams in Arizona always get the home clubhouses? Would they have an advantage from playing in the ballparks during the exhibition season?

THE TUBE

Playing in empty ballparks would keep the money flowing from regional sports networks and the national television contracts with Fox, ESPN and Turner. There might even be expanded national broadcasts.

TESTING

Players, team staff and ballpark, transportation and hotel personnel would have to be tested frequently for the coronavirus.

ISOLATION

What is the rule if a player's wife is giving birth or if he has a sick parent, spouse or child? Would he be allowed to leave? If so, would he be quarantined upon his return?

ROBOTS

Would the automatic ball/strike system being tested in the minors replace home plate umpires calling pitches, thereby allowing them to keep social distance from batters and catchers?

REPLAY

Spring training ballparks are not wired for video review. Would it be worth the cost, or would MLB go back to the pre-2008 human eye standard?

SCHEDULES

With teams in the same area, would three- and four-game series be standard, or would MLB mix it up? During spring training, teams usually switch opponents on a daily basis.
