Major League Baseball and the MLB Players Association agreed to numerous changes that will take effect this season or next, but it sounds like the union was very reluctant on at least one of the new rules.

One major change that will be implemented beginning in 2020 is a three-batter minimum for relief pitchers, which is designed to prevent teams from making excessive pitching changes in the same inning. The only exception to the rule is if a pitcher comes on and finishes the remainder of the half-inning. On Thursday, MLBPA executive director Tony Clark made it clear the union was opposed to that change.
