Doesn't matter. A player doesn't have a right to stand in the ump's face and argue a call. If contact happens while the player is doing that, that's his own fault. I have to disagree. Z has no right to argue and get in the umps face but that is why he gets ejected and potentially suspended if the league rules it necessary. The ump as an, authority figure and one who is supposed to sustain a rule of order, has no right to ensue chaos and bump the player and intensify an already intense situation.
