...I thought of one too. You know how umps have traditionally "given the bag" to the fielder covering 2B on a DP, even though his foot may not have touched the bag while in possession of the ball before relaying the ball to 1B?
...how long, before in a critical point in the game , will a sharp manager demand a replay? This will force the umps to reverse the out call at 2B, and eventually force them to do away with the "phantom" call and scrutinize the play more closely
