Upon Further Review, MLB Weighs Instant Replay

Baseball may begin experimenting with instant replay, starting in the Arizona Fall League and possibly second-guessing big-league umps as soon as next season, a source tells ESPN. But a league official told the AP, "We've made no final decision as to where exactly we're going to try it out, do any test runs or anything yet."

Several recent games have included disputed home run calls, the only play that would be reviewed under the proposed system. Managers favor instant replay. The league official, Jimmie Lee Solomon, notes that fans are "used to seeing the other sports that use these systems to make determinations, and the fans are clamoring for all the sports to look at that."
