Torre said that MLB will not instate expanded replay for the 2013 season BUT in 2014 replay will be expanded to include fair/foul and trapped catches. Plays at the plate may also be included (they should be anyway) as mentioned in the article:
"Torre, who is Selig's point man on the issue, said he understood the commissioner's oft-stated intention to broaden the replay system to include calls of fair balls, foul balls and trapped balls.
However, in the wake of last fall's playoffs, Torre said it became evident that expanded replay should be all-encompassing rather than incremental. He cited one play in particular -- a blown call in the American League championship series, in which Omar Infante of the Detroit Tigers was called safe at second base when replays clearly indicated he had been tagged out.
"We're not going to get caught in the trap of doing something if we don’t feel what we're doing is enough," Torre said."
I think this can be effectively implemented without being time consuming. Only good things can come from this, getting the call right should trump anything else. I am excited to see this take place starting in 2014.
