Yankees @ Blue Jays

[Larry1953]

Batter for Jays hits a grounder for what could be a 6-3. The throw draws F3 Posada off the bag. B/R oversteps first. Angel Hernandez makes no call. Posada makes a deliberate tag of the bag while looking at Hernandez. Still no call. Posada then jogs down the line to tag B/R who is called out.

Question on the mechanics: I have read some threads that say the B/R "attains" first base when he beats the play - even if he misses the bag - and the umpire is to signal safe so as not to tip off the defense that they need to make the appeal. Secondly, why wasn't the deliberate tag of the bag by F3 enough to make the appeal - it looked like he did it twice. Finally, if there were 2 outs and R3 is this a time play where the run would count or would it be "run does not count when the third out is made on B/R at first?
