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. Player leaders from across the league were engaged in on-field rules negotiations through the Competition Committee, and they provided specific and actionable feedback on the changes proposed by the Commissioner’s Office. Major League Baseball was unwilling to meaningfully address the areas of concern that Players raised, and as a result, Players on the Competition Committee voted unanimously against the implementation of the rules covering defensive shifts and the use of a pitch timer.
