Umpires in baseball and the 6 letter word!!

Replay... In todays competitive sports world referees and umpires are under more scrutiny everyday. With the recent follies and missed calls in the championship league series in baseball, many have brought up this 6 letter word... REPLAY. I belive video replay in baseball is a must. Games have been won and lost in the wrong ways by umpire errors. I would never agree with replay on balls and strikes. However, replay should be used for situations such as: fair and foul balls, base-running, and homeruns. Your thoughts....
