Via Bob Nightengale: MLB is prepared to adopt an expanded replay system that would give managers the opportunity to challenge a disputed play. Managers would get three challenges per game but could only use one in the first six innings (wtf?), and most (but not all) plays would be reviewable. Reviews will be made by a central office that will remain in contact with the crew chief.
Expanding instant replay is great and MLB should be all for it, but the manager challenge system is … questionable. There will be a lot of ways to exploit the system, namely by having someone in the clubhouse watching replays before telling the manager to formally issue the challenge. I suppose you could also see a situation where a challenge is made just to give a reliever more time to warm up. I dunno, we’ll see. There is a phasing plan to implement the system in 2014, but the final vote won’t come until the owners’ meetings in November. The players’ and umpires’ unions must sign off as well. Getting the umps to agree could be a headache.
