The Major League Baseball Players Association is mulling over a proposal by MLB to delay the start of the 2021 season, according to sources.

If the union does not provide a counteroffer early next week, spring training is likely to start in mid-February as scheduled.

The league's proposal to push back the start of spring training to late March and the beginning of the season to late April includes a 154-game schedule that would pay players their full 162-game salaries, according to sources.
