All of your questions about the new rules, answered
The 2023 Major League Baseball season brings a wave of rules changes collectively aimed at improving the game’s pace of play and increasing action on the field.
The arrival of the pitch timer, restrictions on defensive shifts and bigger bases makes for one of the more ambitious adaptations to the rule book in the modern era.
So here’s a handy guide to understanding the new rules and why they are being implemented.
What are the new rules?
There are three, and we’ll break them down in detailed sections below.
Pitch timer: The length of games will still be determined by innings, not minutes. But to create a crisper pace, there will be a 30-second timer between batters and then a shorter time limit between pitches. Pitchers will be required to begin their motion 15 seconds after receiving the ball with the bases empty or 20 seconds after receiving the ball with runners on base. If they don’t, they will be charged with an automatic ball.
Shift restrictions: The defensive team must have a minimum of four players on the infield, with at least two infielders completely on either side of second base. These restrictions are intended to increase the batting average on balls in play, and allow infielders to better showcase their athleticism with great defensive plays.
Bigger bases: First, second and third have been expanded from 15 inches on each side to 18 inches on each side, while home plate remains unchanged. The primary reason why the bases are bigger is safety, giving fielders and runners more room to operate without colliding. But the slightly decreased distance between bases could help runners on stolen-base attempts and bang-bang plays.
When do the new rules go into effect?
They will be in effect for all of Spring Training to provide an adjustment period before Opening Day of the 2023 season. Umpires have been instructed to begin calling violations with no grace period.
