This came after news that spring training would be suspended. MLB was smart not to put a firm date on starting the season because we don’t know how long this will go on. They can reevaluate the situation as April 9th approaches, which would be the new start date.
For the Yankees and rest of the league, this would mean about 12 games are missed. They could do some things like skip All Star week or schedule double headers to make up those games. Earlier today I dove into what a shorter season might look like and one – lets call it interesting – idea that has been discussed to recoup lost games.
