Major League Baseball has announced a number of rule changes that will be in effect starting with the 2020 season.
- Pitchers must now face a minimum of three batters or complete the half-inning in question before being removed from the game.
- Each team\'s active roster will expand from 25 to 26 spots for the 2020 season, and teams may now carry no more than 13 pitchers on the active roster at any given time.
- Clubs may not reinstate pitchers or two-way players from the injured list until 15 days have elapsed from the date of the initial roster move.
- Under the old rules, managers had 30 seconds to decide whether to challenge a call on the field. Now that time limit has been reduced to 20 seconds.
