Major League Baseball is prepared to ditch the implementation of a pitch clock until at least 2022, according to sources.

The delay is part of a vast proposal to the MLB Players Association that would include the ability to implement a three-batter-minimum rule for pitchers and roster-size changes in 2020.

According to sources, MLB is also proposing limitations on position players' usage as pitchers, getting rid of the waiver trading period, further cutting mound visits and potentially shortening inning breaks.
