This discussion brings to mind the story about the famous umpire Bill Klem. The ball and the runner arrived at second base in a cloud of dust. The fielder applied the tag, then jumped up and said to Clem, "Is he safe or is he out?" and Clem replied, "He ain't nuthin' 'till I call it." Whether we use electronics to ensure the call is right is now moot. What if the umpire got the call wrong? What recourse is there for the "injured party"? Well, the umps can conference and maybe put a runner back on the base. But some calls are not reviewable (by rule). What then? Remember, there is no more "playing the game under protest" with hope a higher authority will do something (has a game ever been replayed because of such a situation? I'd guess never.). Protests have been eliminated - one of the rules they slid in under the smoke screen when other rules were implemented this year (e.g.- seven inning games in doubleheaders and runner on second base to start extra innings). It should go back to the umpires getting the call right, and if there's a question about an interpretation of the rules (e.g.- ball hit a wall over or under the home run line, fair or foul), deciding it with a meeting of the umpires. Other plays, where a rule interpretation is not involved (e.g- tag plays), should not be reviewable. BUT, there should be stricter enforcement of umpire evaluations, to make sure the most capable umpires are still there and bad ones culled out. Right now, that is close to impossible, but it is a change that must be made by MLB. Later
