Tigers vs Injuns 5-1-09 Laz Diaz? no-call

[UmpTTS43]

I did not see the play or the video, however I would say he used incorrect mechanics based on today's interpretations. If the tag of first was not deemed an "unmistakable appeal" then I can see how it was not upheld. There are still too many differing interps considering missed base appeals. The only ones in print, that I know of are: MLBUM, which seems pretty clear to me, Wendelstedt and J/R, both of which are contradictory. I have always viewed J/R as AN interpretation, not an OFFICIAL interpretation.
