Baseball is doing its best to get things back to normal, restoring the 162-game season and starting the year with fans in the stands of every stadium.

Some policies set by Major League Baseball are locked in at every park, like fans being required to wear masks, but the policies diverge based on the rules in the city or state where the game is being played. Nothing, however, is set in stone, as the rules could be tightened or relaxed based on how things are going in terms of coronavirus infections.

Anthony Fauci, the U.S. government’s top infectious disease expert, said in a recent interview with “Face the Nation” that he expected the restrictions to lessen as the season progressed.

“I would expect that as we get through the summer — late spring, early summer — there’s going to be a relaxation where you’re going to have more and more people allowed into baseball parks, very likely separated with seating, very likely continue to wear masks,” he said.
