MLB commissioner Rob Manfred has put an emphasis on improving pace of play in recent years, making changes such as eliminating the need to throw four pitches for an intentional walk and limiting managers to 30 seconds to decide if they want to challenge a play.
Manfred recently came up with a revised proposal that he presented to the Players’ Union in regards to the initiatives that he would like to put in place for the 2018 season. They included a 20-second pitch clock and limiting the number of times a catcher could visit the mound.
