Dawn of a new era
What’s next? The plan for a dramatically expanded MLB replay system will be put to a vote at the next owners meetings in November. With the expected cooperation of both the Players Association and the umpire’s union, it should be in place by Opening Day next season.

How will it work? Managers can issue one challenge in the first six innings and two from the seventh inning on. If the manager correctly challenges a play in the first six innings, he will retain his option to challenge future plays. If the review upholds the decision on the field, the manager loses his challenge until the seventh inning, when the clock resets.
