Sherman spoke to a team executive who said closing stadiums to the public will allow for an earlier start: "By a matter of weeks, we will be able to play games without crowds [before we can play games] with them."
Another official speculated playing without fans will be the "only way we play" until the COVID-19 pandemic is contained.
ESPN's Jeff Passan reported Thursday that MLB and the MLB Players Association reached an agreement regarding player salaries and service time with the season on hold. The deal included language about the potential resumption of play.
The parties were hopeful of getting training camps started in mid-May and then beginning games in June.
Sherman added that MLB and the MLBPA agreed to wait until government officials give the green light for large public events again. Commissioner Rob Manfred will also need to feel comfortable there won't be "unreasonable health and safety risk to players, staff, or spectators" by staging games.
A June restart might be too optimistic given the recent rise in coronavirus cases in the United States. The U.S. has more confirmed cases (165,874) than any other country, per CNN.
Toronto Mayor John Tory on Tuesday announced the cancellation of all major events through June 30 to try to limit the spread of COVID-19. That presumably rules out home games for the Toronto Blue Jays until July at the earliest.
Simply prohibiting fans from attending games may not be enough to allow for baseball to return in the near future.
