Major League Baseball passed a sweeping set of rules changes it hopes will fundamentally overhaul the game, voting Friday to implement a pitch clock and ban defensive shifts in 2023 to hasten the game's pace and increase action.

The league's competition committee, composed of six ownership-level representatives, four players and one umpire, approved a pitch clock of 15 seconds with empty bases and 20 seconds with runners on, a defensive alignment that must include two fielders on each side of the second-base bag with both feet on the dirt as well as rules limiting pick-off moves and expanding the size of bases.
