Microphones for umpires?

[Fan10]

Occasional reader; it was this play that made me decide to register and post.

As my screname indicates, I am just a Fan. But, I have always made it a point to try and understand the rules (partially by occasionally reading these boards).

It appears to me that they ruled type A obstruction since they declared the ball dead. I have always understood that type A obstruction is called only when at the time of the obstruction, a play is being directly made on a runner (such as a rundown). At the time of the obstruction in this play, the ball was either in the outfield or in the air from the outfield to the infield. So, how is this type A obstruction when at the time of the obstruction, no play was being directly made on the runner?

And, second, type A obstruction per MLB rules requires a minimum of a one base award. It appeared to me that the obstructed runner was standing on second base when he was obstructed. So, why is he not awarded third (and if you award him third, what do you do with the lead runner who was caught in the rundown between 3B and home)?

I sure wouldn't put my knowledge of the rules up against Joe West, so I'm sure he got this right. But, these were just a few things that didn't seem right based on my knowledge of the rules.

Thanks in advance.
