What new MLB rules are in place for 2023?

In an effort to accelerate the pace of games, increase offense and add a layer of safety, MLB has instituted three new rules. They were used throughout spring training and will be in effect during postseason play, too. The result during spring play was a reduction of average game times by 25 minutes compared to 2022, according to MLB Network.

Pitch clock: A timer will be used to move games along and cut down on wasted time. There will be 30 seconds between batters, then pitchers must begin their motion 15 seconds after receiving the ball with the bases empty, 20 seconds with runners on base. They will be charged with a ball if the clock expires. Also, with runners on base pitchers will be limited to two pick-off or rubber step-offs per plate appearance. The clock resets each time.

Batters need to be in the box and ready for the pitch with 8 seconds left the clock, or else be charged with a strike. Batters are allowed to step out once per appearance.

End of the overshift: No more team meetings on one side of the playing field. Teams must have at least four players on the infield, and at least two defenders on each side of second base. The thinking is this will increase batting average on balls in play.

Bases are bigger: First, second and third base are now 18 inches on each side, up from 15. The idea is the larger bases might cut down on collisions between fielders and runners, especially at first.
