Orioles vs. Yankees - Aug 23

[VanStanza]

I was watching sport highlights this morning and saw a replay of a controversial call in yesterday's game. An Oriole (Melvin Mora, I think) struck out on a dropped 3rd strike. He hesitated, and as the Yankee defense was leaving the field, decided to run uncontested to 1st base. Initially, the umpires allowed him to stay, but after a Joe Girardi argument, changed their call.

Did I see the whole incident?

What do you guys think about this?

I'm not sure who the PU was, but, on an unrelated note, was wearing a plate coat with the chest protector showing through, which I have always thought looks unprofessional.
