Beginning May 2, MLB teams will be allowed to keep 26 players on the active roster. When that happens, no more than 13 of those players must be pitchers. In practice, most teams will wind up keeping 13 pitchers and 13 position players.
But through games of May 1, MLB and the MLB Players Association agreed to allow teams to keep 28 players active, largely because of the shortened Spring Training, which will be fewer than four weeks long and with most teams playing 20 or 21 games.
Many have said that the Cubs should keep 15 pitchers during this expanded roster time.
