Pitch clocks and shift limits: MLB adopts sweeping rule changes for 2023

Major League Baseball adopted its first pitch clock, limits on defensive shifts and larger bases for next season in an effort to shorten games and increase offense in a tradition-bound sport.

The decision on the clock and shift restrictions by the sport’s 11-man competition committee was made Friday over the unanimous opposition of the panel’s players, who approved the larger bases. The changes had long been pushed by baseball commissioner Rob Manfred in an effort to combat the increase in dead time over four decades and suffocation of offense in the age of analytics.

“Throughout the extensive testing of recent years, minor league personnel and a wide range of fans – from the most loyal to casual observers – have recognized the collective impact of these changes in making the game even better and more enjoyable,” Manfred said in a statement.

Until last winter, MLB needed one year advance notice to make on-field rules changes without approval of the players’ association. The union agreed in the March lockout settlement to establish the committee, which includes six management representatives, four players and one umpire.

“Players live the game – day in and day out. On-field rules and regulations impact their preparation, performance, and ultimately, the integrity of the game itself,” the union said in a statement. “Major League Baseball was unwilling to meaningfully address the areas of concern that players raised.”The pitch clock will be set at 15 seconds with no runners on base and 20 seconds with runners – up from the 14/19 tested at Triple-A this season and 14/18 at lower minor league levels.

There will be a limit of two of what MLB calls disengagements – pickoff attempts or steps off the rubber – per plate
