I'm all for some form of instant replay, but you don't even need it on this play. The other umps need to get theirs heads out of their asses, put their attitudes aside and then help Welke out on this play and get the call correct.
Welke is an ass-clown for not accepting help on this play. AND for lying to Don Mattingly's face. If you watch the video linked here -
