Instant replay will be used in all ballparks starting Sept. 1 as long as there are no technical difficulties. Replays will only be used for boundary issues for home runs. My question is why now? Why not wait until the start of next season? I am against replay in baseball but if you are going to do it, do it right. Let the problems be worked out during spring training not during the last month of the season when teams are in the middle of a pennant race. More Bud being Bud.
