A number of playing rule changes for Major League Baseball games have been previously announced: The universal designated hitter, various roster rules and limits, and the ghost runner in extra innings (popularly known as the Manfred Man).
Morgan Sword, MLB’s Executive Vice President, Baseball Operations, said in a statement: “As part of our discussions with the MLBPA regarding the condensed 162-game schedule, we have agreed to extend the extra-innings rule to the 2022 Championship Season and temporarily expand rosters. We are excited to see the universal designated hitter in action this season with amended rules that will promote the use of two-way players going forward.
