Well at least baseball is trying to make progress regarding replay: MLB GM's vote for some replayThe proposal, approved by a 25-5 vote, was limited to boundary calls -- whether potential home runs are fair or foul, whether balls go over fences or hit the tops and bounce back, and whether fans interfere with possible homers.
I would like to see replay implemented where the head umpire could pick up the phone, ask the replay umpire to make the call. One quick question and answer. I could see it expanded to include out calls (i.e. trapped balls or extremely close plays on the bases) but wouldn't want it to be used on every call. Need some way to regulate it usage.
