While MLB generated record revenues during the 2018 season, one issue that has continued to hover over commissioner Rob Manfred and the sport as a whole is pace of play. Last year saw sweeping changes in the Minor Leagues, including putting a runner in scoring position for games that reach extra innings.
Such a rule, and others, was discussed between the MLB and MLB Players Association, but ultimately was not implemented at the big league level. There were new rules for non-pitching change mound visits and the replay process.
One change that Manfred ultimately held off on imposing was a pitch clock.
