Starting next season, managers in Japan will be able to request video reviews of calls on the field of play following a decision on Monday by Nippon Professional Baseball.
Until now, video reviews were restricted to three plays, balls caught against an outfield wall or fence, plays at the plate and potential home runs. These reviews were ostensibly only initiated by the umpires.
Under the request system, potential home runs and safe and out calls on the bases may be challenged. Each team will be able to request reviews until two requests through nine innings have failed to overturn rulings. Teams will be allotted an additional request in extra innings.
