Significant rule changes are about to come to Major League Baseball.

MLB is expected to approve several changes for the 2023 season in a vote Friday, including a pitch clock and defensive shift bans, sources told Evan Drellich and Ken Rosenthal of The Athletic.

The changes have been recommended by an 11-person competition committee, which was formed earlier this year as part of the new collective bargaining agreement. The committee consists of six members appointed by MLB, four members of the players' association, and one umpire.

Perhaps the most notable change involves the implementation of a pitch clock, which has been tested in the minor leagues. Under the new rule, pitchers would have 20 seconds to begin their throwing motion with runners on base and 15 seconds if the bases are empty, Drellich and Rosenthal report. Automatic balls could be called if pitchers violate the clock, while batters would face an automatic strike if they take too long.
